As a result of ubiquitous impermeable surfaces, conventional water management and stormwater infrastructure, and the resultant degradation of natural hydrologic networks, most American urban areas have suffered severely compromised hydrological function and health, particularly related to stormwater and its storage, treatment, and flow. Negative externalities exist at multiple scales: increased disaster vulnerability, climate change, poor water quality, habitat loss, etc. Because upgrading conventional single-purpose infrastructure has become an increasingly cost-prohibitive option, urban areas are finding that reincorporating natural systems can be more effective. In the last 20 years, constructed wetlands have arisen as a promising multi-purpose solution to stormwater problems. Constructed wetlands are artificial systems designed to mimic natural wetlands by using the same physical, biological, and chemical processes to treat water. They are relatively large, but their size gives them high ecological potential and numerous other benefits, such as flooding protection and recreational spaces, while having low life-cycle costs. Since the effectiveness of constructed wetlands comes from mimicking natural wetlands, then the analogy to nature should be extended as far as possible. In nature, wetlands are a system connected to a regional hydrologic network. Therefore, constructed wetlands distributed systemically throughout a watershed have potential to deliver more networked benefits than the current practice of dispersed and disconnected wetlands for individual sites. Yet little research exists examining the implications of urban constructed wetlands in design and planning terms, at multiple scales. In fact, few urban constructed wetland projects for stormwater exist in the first place. This thesis proposes a framework for understanding the potential of systemic constructed wetlands as landscape infrastructure in urban areas. Based on an understanding of science, engineering, and urbanism, this thesis identifies the urban zones of greatest potential for stormwater constructed wetlands and suggests the benefits that could arise out of an urban constructed wetland system, beyond simply water treatment.

Pełny tekst źródłaÖvergödning är ett stort problem som orsakar algblomningar och försämrad vattenkvalitet, särskilt vid kustområden och hav. Övergödningen orsakas av ett för stort utsläpp av näringsämnen såsom fosfor (P), där jordbruket står för den största antropogena näringsbelastningen. Åkermark med lerjord har dessutom visat sig ha bland den högsta utlakningen av P. I denna studie har 10 våtmarker anlagda i jordbruksområden med hög lerhalt undersökts. Syftet var att undersöka hur P-ackumuleringen är relaterad till våtmarksutformningen och abiotiska faktorer i avrinningsområdet. Projektet syftade även till att undersöka ifall det finns en optimal hydraulisk belastning (HL) för P-ackumulering. Studien baserades på P-analyser av sedimentproppar provtagna i mars 2021, beräkningar av avrinningsområdesfaktorer i ArcMap, flödesberäkningar samt statistiska analyser. Den primära reningsprocessen för P i våtmarker är genom sedimentation av partiklar med bundet P. Följaktligen visade resultatet att P-ackumuleringen var positivt korrelerad med partikelretentionen. Den totala P-ackumuleringen varierade mellan 8 och 96 kg ha-1 år-1 och den totala partikelackumuleringen var 7-130 ton ha-1 år-1. Våtmarksutformningen, vilket innefattade våtmarksarea, vattendjup och längd-bredförhållande (L:W), hade ingen signifikant betydelse för P-ackumuleringen. Vattendjup större än 1,5 m hämmade emellertid P-ackumuleringen vilket indikerade att vattendjupet bör begränsas till cirka 1 m för att partiklar ska hinna sedimentera. Andelen jordbruksmark i avrinningsområdet hade ingen korrelation med P-ackumuleringen. Lerhalten i avrinningsområdet var däremot positivt korrelerad till både partikel- och P-ackumuleringen. Detta indikerade att sedimentationen främjats trots att de inflödande partiklarna potentiellt bestod av en stor andel lerpartiklar, vilka har en långsam sedimentationshastighet. Erosionsrisken i avrinningsområdet hade ingen signifikant påverkan på P-ackumuleringen. En hög förväntad partikelbelastning resulterade därmed inte en ökad partikel- och P-ackumulering. Höga HL-värden på 450 och 850 m år-1 motverkade P-ackumulationen, vilket motsvarade våtmarker som utgjorde mindre än 0,1 % av avrinningsområdet. En möjlig brytpunkt där HL hämmar P-ackumulationen kunde urskiljas i intervallet HL 200-300 m år-1. På grund av för få observationer kunde inte en optimal HL för ökad P-ackumulation fastställas. Det kunde dock konstateras att en HL upp till cirka 210 m år-1 hade en positiv inverkan på partikel- och P-ackumulationen och att våtmarker bör utgöra minst 0,1 % av avrinningsområdet för att effektivt ansamla P.

Pełny tekst źródłaDes méthodes à la fois in vivo et in vitro servirent à élucider le devenir et le comportement de trois antibiotiques ionophores (monensin, salinomycine and narasine) dans l'environnement d'un marais artificiel (MA). Des études in vitro en laboratoire établirent le potentiel de sorption et de décomposition de ces composés dans un loam sablo-argileux et un sol sableux, ainsi que celui de photodégradation dans l'eau de marécage. Des études avec MA à l'échelle préindustrielle déterminèrent le potential d'élimination de ces trois produits pharmaceutiques sous trois types d'écoulement: en surface libre (FWS), souterrain horizontal (HSSF) et en circulation verticale (VF). Le système FWS fut évalué avec les deux types de sols, tandis que le système HSSF ne fut évalué que pour le sol sablonneux. Le système de circulation en vertical utilisa de la tourbe mousseuse de sphaignes. In vitro le niveau de sorption des composés présenta une relation inverse au pH pour des valeurs de 4.5, 6.8, and 8.5. À un pH de 6.8, les valeurs de Kd pour tous les composés furent plus élevés pour le loam sablo-argileux que pour le sol sableux. La narasine montra les valeurs les plus élevées de Kd and Koc, tandis que le monensin montra les moins élevées. Trois concentrations (100, 500, et 1000 μg kg-1) de chaque composé, appliqués sur chacun des deux sols, présentèrent tous une cinétique de dégradation de premier ordre, avec des demi-vie d'élimination de 6 à 8 jours. Le potential de photodégradation des trois composés fut évalué dans de l'eau de marécage pré-stérilisé, de l'eau distillé (milli-Q) et de l'eau distillé dopé de nitrates. La photodégradation n'eut lieu que dans l'eau de marécage, où elle suivit une cinétique de dégradation de premier ordre, avec des demi-vies d'élimination de 55, 40, et 37 jours, respectivement, pour le monensin, la salinomycine, and la narasine. Dans une première étude, on évalua l'éfficacité d'élimination de ces composés par les deux systèmes FWS — un avec loam sablo-argileux et un avec sol sableux — et un système VF avec tourbe mousseuse de sphaignes. Le système FWS avec sol sableux comme substrat élimina significativement plus les trois antibiotiques (P< 0.01) que celui avec un loam sablo-argileux. La capacité des composés dissouts de pénétrer le profil sableux permit probablement des conditions plus favorables aux interactions sol-soluté. Ceci aurait ensuite permis une plus ample atténuation, principalement par sorption au sol sablonneux. Le rôle de la biodégradation, particulièrement dans le loam sablo-argileux, fut aussi noté. Cependant, comparé aux systèmes FWS, le système VF avec tourbe permit une élimination significativement plus élevée (P < 0.0001). Dans les trois systèmes, le monensin et la narasine s'avérèrent les composés le plus et le moins mobile, respectivement. Dans une seconde étude on évalua le potentiel d'élimination des trois antibiotiques grâce à un système HSSF pleine échelle avec sol sablonneux. Comparé au système FWS comportant le même substrat, le système HSSF élimina significativement (P < 0.01) plus de monensin (40% vs. 32%), salinomycine (49% vs. 34%) et narasine (49% vs. 38%). Un suivi de la température, du potentiel d'oxydo-réduction et de l'oxygène dissout, ne permirent pas de confirmer une contribution significative de la dégradation microbienne.En une dernière étude, des souches bactériennes compétentes à l'élimination de l'azote furent isolées d'un marécage exposé à des antibiotiques. Ces souches furent identifiées par détermination de la séquence nucléotidique d'ARNr 16s, et leur capacité de résister à ces composés pharmaceutiques fut évaluée. Une souche de Bacillus subtilis (BRAZ2B) s'avéra capable de se développer vigoureusement dans l'environnement du marécage exposé à ces composés.

Pełny tekst źródłaPesticides used to improve the quality of agricultural products are a source of non-point source pollution that affects the quality of water resources and aquatic habitats. Several studies have evidenced that natural (e.g., lakes, ponds, and bogs) or constructed wetlands (e.g., ponds, irrigation reservoirs, and drainage ditches) that intercept agricultural waters can dissipate pesticide contamination. Thus, this thesis aims to study the fate of pesticides in constructed wetlands (ponds). Ponds were originally constructed to store rainwater and agricultural drainage water to provide water for livestock and irrigation. However, several research studies have demonstrated the environmental benefits of ponds. In addition to providing a habitat for living organisms, they can dissipate the concentration of pesticides contained in agricultural waters. When the pesticides remain in the ponds, they undergo a series of physicochemical processes that reduce their concentration. Subsequently, when the ponds are filled, the water is discharged to the surface, and groundwater sources are less pesticide-loaded. Therefore, as a complement to pesticide use regulations, ponds are an effective tool for reducing pesticide transfer to water resources downstream of agricultural plots. Although many studies of the dissipation potential of ponds focus on nitrates and suspended sediments, very little is known about the behavior of pesticides. Furthermore, most studies evaluate a dissipation process individually without focusing on its potential interaction with other processes. Even fewer papers present mathematical formulations for dissipation processes to develop predictive models. The first objective of the thesis is to study and assess the interactions and contribution of multiple physicochemical processes to pesticide dissipation in ponds, as well as their mathematical formulations and main controlling factors. The quantification of the contribution of each process to pesticide dissipation in ponds allowed the construction of primary process hierarchization hypotheses. In the second phase, the findings of this process investigation and the selected mathematical formulations were used to develop a conceptual model of pesticide fate in the ponds. The model integrates the different processes of transport, transfer, and transformation within the main compartments of the ponds (water and sediments) to predict the dynamics of the pesticides. A sensitivity analysis was performed to identify the most involved processes in pesticide dissipation: sorption, transformation by microorganisms, and photolysis. The model was then applied to a typical agricultural pond in a drainage area (Rampillon, France) where pesticides are mostly transported in a dissolved form in the catchment. The application results enabled to display of the temporal distribution of pesticides in the pond and the contribution of each process to the dissipation of pesticides. The model was also applied to another pond (Auradé, France) representing erosive media to characterize pesticides' particle form behavior

Pełny tekst źródłaENGLISH ABSTRACT: Constructed wetlands have been widely used in the treatment of industrial and domestic wastewater to reduce biological and chemical oxygen demand (BOD and COD), to remove nitrate and enteric viruses as well as to generally improve water quality. Distillery wastewater has a complex character due to high concentrations of sugars, lignins, hemicellulose, dextrins, resins, polyphenols and organic acids, leading to a high COD that may exceed 100 000 mg/L. The potential application for the treatment of distillery wastewater by means of constructed wetlands is relatively unexplored. In 1999 a study was initiated at Distell Goudini distillery, Western Cape, South Africa, to explore the possibility of using constructed wetlands to treat distillery wastewater. It was found that constructed wetlands do have the ability to treat distillery wastewater providing that the influent COD does not exceed 15 000 mg/L for extended periods and the correct substrate material is used. The present study expanded on the above-mentioned study and specifically aimed to provide information on the microbiological controls in wetland systems in an applied sense that may contribute to improved treatment efficiency. Furthermore, this project aimed to contribute to our fundamental understanding of the microbial ecology of constructed wetlands used for the treatment of distillery wastewater. This study revealed that a highly dynamic microbial composition exists within wetlands. Furthermore it was found that wetlands can efficiently remove COD even though a low degree of similarity exists between microbial communities in various zones of the same wetland and those between different wetlands, as well as low similarity between communities sampled from the same zone over time. This demonstrates that it will be difficult to define the ‘ideal’ degradative community in terms of microbiological criteria and serves as a reminder that various indicators should be considered for monitoring system health. Furthermore the shifts in microbial community composition illustrate the ability of microbial communities to adapt to changes in the environment without compromising their functional efficacy. When studying the attached microbial communities within wetland systems it was found that different morphotypes are detected at certain stages of biofilm development while some organisms are present at most phases of biofilm formation. Measurement of CO2 production and dissolved organic carbon (DOC) removal in laboratory scale columns showed that grazing protists had a notable effect on overall microbial activity and that organic loading influenced these predator-prey interactions. Interestingly, increased clogging of pores occurred in the presence of protists, resulting in reduced flow through the porous matrix. Terminalrestriction fragment length polymorphism (T-RFLP) analysis of biofilms on gravel in experimental wetlands indicated that the presence of protists and algae had an effect on the microbial community composition. Scanning electron microscopy (SEM) showed that the presence of algae also had an influence on biofilm structure suggesting that the algae provided labile nutrients that were utilized by the bacterial and yeast members of the community. Finally, augmentation with a commercial mixture or microbial populations isolated from distillery effluent demonstrated that the concentration at which supplements are applied influence degradative efficiency.
AFRIKAANSE OPSOMMING: Kunsmatige vleilande word wêreldwyd gebruik in die behandeling van indusriële en huishoudelike afvalwater om biologiese en chemiese suurstof aanvraag (BSA en CSA) te verminder, om nitrate en ingewandsvirusse te verwyder asook om waterkwaliteit in die algemeen te verbeter. Distilleerafvalwater het komplekse eienskappe as gevolg van hoë konsentrasies suiker, lignien, hemisellulose, dekstrien, harpuis, polifenole en organiese sure, wat lei tot ‘n hoë CSA wat 100 000 mg/L kan oorskry. Daar is tot op hede relatief min studies gedoen oor die potensiële gebruik van kunsmatige vleilande vir die behandeling van distilleerafvalwater. In 1999 is ‘n studie by Distell Goudini distilleeraanleg in die Wes Kaap van Suid Afrika onderneem om die moontlikheid van kunsmatige vleilande vir die behandeling van distilleerafvalwater te bestudeer. Daar was bevind dat kunsmatige vleilande die vermoë het om distilleerafvalwater te behandel gegewe dat die invloeiende CSA nie 15 000 mg/L oorskry nie en dat die regte substraat materiaal gebruik word. Die huidige studie het by die bogenoemde studie aangesluit met die doel om informasie oor die mikrobiologiese kontroles in vleilandsisteme op ‘n toegepaste wyse te voorsien, wat tot verbeterde behandeling doeltreffendheid kan lei. Hierdie studie het verder beoog om by te dra tot ons fundementele kennis van die mikrobiese ekologie van kunsmatige vleilande wat gebruik word vir die behandeling van distilleerafvalwater. Dié studie het bevind dat daar ‘n hoogs dinamiese mikrobiese samestelling binne vleilande bestaan. Daar was verder bevind dat CSA steeds effektief deur vleilande verwyder kan word alhoewel daar ‘n lae graad van ooreenstemming is tussen mikrobiese gemeenskappe in verskeie sones van dieselfde vleiland en verskillende vleilande, asook ‘n lae graad van ooreenstemming tussen gemeenskappe wat in dieselfde sone oor tyd gemonster is. Dit demonstreer dat dit moeilik sal wees om die ‘ideale’ degraderende gemeenskap te vind in terme van mikrobiologiese kriteria en dien as ‘n herinnering dat verkeie indikatore in ag geneem moet word om die welstand van ‘n ekologiese sisteem te monitor. Die verskuiwings in mikrobiese gemeenskapsamestelling illustreer verder die vermoë van natuurlike sisteme om aan te pas by veranderinge in die omgewing sonder om funksionele doeltreffendheid te verminder. Die studie van aangehegte mikobiese gemeenskappe het aangedui dat veskillende morfotipes bespeur kan word tydens sekere fases van biofilm formasie terwyl sekere organismes tydens meeste van die fases teenwoordig is. Die bepaling van CO2 produksie en die verwydering van opgeloste organiese koolstof in laboratoriumskaal kolomme het geïlustreer dat voedende protiste ‘n waarneembare effek gehad op die algehele mikrobiese aktiwiteit en dat die organiese lading hierdie predator-prooi interaksie beïnvloed het. Dit was interessant om te vind dat die teenwoordigheid van protiste die verstopping van porieë aangehelp het en dus tot verlaagde vloei deur die poreuse matriks gelei het. Terminale-restriksie fragment lengte polimorfisme (T-RFLP) analiese van biolfilm op klipgruis in eksperimentele vleilande het aangedui dat die teenwoordigheid van protiste en alge ‘n effek gehad het op die mikrobiese gemeenskapsamestelling. Skandeerelektronmikroskopie (SEM) het bewys dat die teenwoordigheid van alge ook ‘n invloed op biofilm struktuur gehad het wat daarop dui dat alge maklik afbreekbare voedingstowwe aan die bakterieë en giste van die mikrobiese gemeenskap beskikbaar gestel het. Laastens was bewys dat die konsentrasie van toevoeging van ‘n kommersiële mikrobiese mengsel of mikrobiese populasies wat uit afvoer geïsoleer was, die effektiwiteit van degradering kan beïnvloed.
