Texte intégralThe treatment of sludge produced by wastewater treatment plants (WWTP) represents a major challenge for the optimization of energy consumption and material flows. Among emerging processes, thermal treatments have many interests: increased methane production in anaerobic digestion, improved dewaterability by centrifugation and hygienization of sludges. However, they produce biorefractory organic compounds, also called melanoidins, through Maillard reactions. Those very diversified compounds are characterized by a high molecular weight, a polymeric and unsaturated structure, and a high nitrogen content. Their refractoriness prevents their biodegradation in common WWTP biological processes, leading to an increase of COD and TKN in the plant discharge.This thesis aimed to answer two main questions:- How to quantify and qualify biorefractory compounds formed by thermal processes?- How to degrade or to enhance the biodegradability of biorefractory compounds formed by thermal processes?First, an analytical method has been developed to characterize melanoidins, based on size exclusion liquid chromatography with UV and fluorescence detection (UPLC-SEC-UV-Fluo). Statistical treatment of the data by artificial neural network and principal component analysis led to an innovative characterization of melanoidins.Centrates of thermaly treated sludge from two WWTP (110,000 and 950,000p.e.) were studied. The method displayed a good ability to differentiate refractory compounds from each other and from biodegradable compounds.Our study exhibited that biological sludge produces twice as much refractory compounds than primary sludge. Moreover, the structure of refractory compound is linked to the process’ temperature and the sludge’s origin from, but it does not depend on the type of sludge thermally treated.Then, the degradation or biodegradability enhancement of refractory compounds by both ozonation and electro-oxidation was investigated.The ozonation was studied through an experimental plan to evaluate the impact of pH and concentrations of refractory COD, biodegradable COD and N-NH4+, on refractory molecules. Our results showed that ozonation can increase the biodegradability; its performances are influenced by pH and concentration of refractory COD. Optimal conditions can reduce the dose of ozone needed by two to three times. The UPLC-SEC-UV/Fluo method was then used to identify the chemical structures and the parameters predicting the biodegradability of refractory compounds during ozonation.The feasibility of electro-oxidation of refractory compounds was first assessed with a boron doped diamond anode. As a result, a complete mineralization was achieved for both organic nitrogen and COD. Therefore, active anodes were tested and highlighted a biodegradability enhancement when adding chlorine as electrolyte.Both technologies demonstrated up to 70% of refractory COD and organic nitrogen removal, decreasing substantially their recycling to the head of the plant.In the last part, the whole UPLC-SEC-UV/Fluo characterization method has been discussed in its potential and with respect to the literature. Finally, the benefits and possible drawbacks of each oxidation technology and their implementation at industrial scale were discussed

Texte intégralMånga av Sveriges små avloppssystem är gamla och saknar tillräcklig rening av fosfor, kväve och organiskt material. Följden är förorenat grundvatten samt övergödning i hav, sjöar och vattendrag. Lösningar för att förbättra fosfor- och kvävereningen finns på marknaden men många har visat brister i rening och robusthet. Biokol är ett material som har föreslagits som ersättare till jord eller sand i mark och infiltrationsbäddar. Denna studie syftade till att i skak- och kolonnfilterexperiment jämföra fosforreduktion mellan tre modifierade biokol och ett obehandlat biokol. Modifieringen av biokolet innebar impregnering med järnklorid (FeCl3), kalciumoxid (CaO) samt blandning med Polonite som är en kommersiell produkt för fosforrening. För att undersöka förbättring av kväverening installerades även ett filter med obehandlat biokol där en vertikal aerob modul kombinerades med en efterföljande horisontell anaerob modul. Skakstudien där biokolen skakades i 3.3 mg/L fosforlösning visade att adsorptionen var högst i det CaO-impregnerade biokolet, 0.3 ± 0.03 mg/g. Den maximala potentiella fosforadsorptionen beräknades dock vara högst för biokolet som impregnerats med FeCl3, 3.21 ± 0.01 mg/g. Skakförsöket visade också att fosforadsorptionen var främst kemisk då adsorptionen passade bättre med pseudo andra ordningens modell än pseudo första. Adsorption av fosfor på obehandlat biokol och FeCl3 impregnerat biokol modellerades bäst med Langmuir modellen, vilket tyder på en homogen adsorption. Det Polonite-blandade biokolet och CaO-impregnerade biokolet modellerades bäst med Freundlich modellen vilket är en indikation på en heterogen adsorptionsprocess. Biokol impregnerat med CaO och FeCl3 gav de högsta totalfosforreduktionerna på 90 ± 8 % respektive 92 ± 4 %. Biokolet som var blandat med Polonite hade en reduktion på 65 ± 14 % och det obehandlade biokolet 43 ± 24 %. Ett problem med filtratet från CaO-filtret var att det fick en rödbrun färg samt en fällning vilket kan ha berott på ofullständig pyrolysering och impregnering. Filtratet från det FeCl3 impregnerade biokolet hade mycket lågt pH vilket kan vara problematiskt om mikrobiologisk tillväxt i filtret för rening av kväve och organiskt material vill uppnås. Filtret för kväverening gav en total kvävereduktion på 62 ± 16 % vilket är högre än kommersiella system. Resultaten från skak och filterstudien visade på att impregnerade biokol kan ge en förbättrad fosforrening om de skulle användas i små avloppssystem. Rening av organiskt material, kemisk syreförbrukning (COD), var dock låg i alla filter och behöver studeras ytterligare för att avgöra om dessa biokol är lämpliga för småskalig avloppsvattenrening.

Texte intégralMặc dù có những đóng góp tích cực cho sự phát triển kinh tế - xã hội, việc phát triển chăn nuôi lợn đã gây ô nhiễm môi trường nghiêm trọng. Hiện nay, nước thải chăn nuôi lợn từ các cơ sở chăn nuôi sau xử lý vẫn chưa đáp ứng được các tiêu chuẩn thải của quốc gia và tiêu chuẩn ngành. Bài báo này trình bày kết quả nghiên cứu về khả năng loại bỏ COD, nitơ (N) và phôtpho (P) trong nước thải chăn nuôi lợn đã qua xử lý bằng hầm biogas của hệ thống phối hợp cây Sậy, Thủy Trúc, cỏ Vetiver và Bèo Tây ở qui mô pilot. Kết quả thực nghiệm ở tải lượng 47,35 l/m2.ngày, với COD, tổng nitơ (TN) và tổng phôtpho (TP) đầu vào trung bình là 203,24 mg/l, 111,94 mg/l và 13,61 mg/l, tương ứng, thì hiệu suất xử lý lần lượt là 71,66 %; 79,26 % và 69,65 %. Như vậy lượng TN và TP loại bỏ là 4201,35 mgN/m2.ngày và 448,76 mgP/m2.ngày. Kết quả nhận được cho thấy hệ thống sử dụng cây Sậy, Thủy Trúc, cỏ Vetiver và Bèo Tây có hiệu quả loại bỏ COD, TN và TP khá cao trong khi vận hành đơn giản nên có triển vọng áp dụng trong điều kiện thực tế để xử lý nước thải chăn nuôi lợn. Tuy nhiên để đánh giá tính ổn định, hệ thống cần được hoạt động với thời gian lâu dài hơn.
