The thesis is a contribution for the methodology to be applied for the treatment of polycyclic aromatic hydrocarbons (PAHs) contaminated soils. The aspects covered are the soil bulk handling, analysis for monitoring the cleanup, the treatability study, the conduct of laboratory testing ant the mathematical modeling of the treatment

In order to clean up polycyclic aromatic hydrocarbon (PAH) contaminated soils, various techniques have been developed during the last decades, but their impact on soil functions was rarely considered. The objective of this study was to assess the impact of chemical oxidation treatments on different physico-chemical and biological parameters of PAH contaminated soil and to propose solutions to improve the biological functioning of oxidized soil. Various laboratory and field experiments have shown that the efficiency of chemical oxidation reactions (Fenton reaction and activated persulfate) on PAH concentrations depended on pollutant availability and soil physico-chemical properties. Besides, intense acidification processes have been observed on uncarbonated soil with a strong impact on soil physico-chemical and biological parameters. Moreover, this alteration was higher with activated persulfate treatment, leading to the loss of trace metals in water percolation. In the strongly acidified soil, the input of materials, suitable for pH increase, resulted in the restoration of biological activities and soil capacity to support vegetation. The association of chemical oxidation treatment and restoration techniques could present a good mean for soil rehabilitation. Finally, an index, which aimed to represent soil conditions based on the weight given to different parameters, was proposed and was used to evaluate changes induced by oxidation treatments and restoration techniques

Wu, Yingxin. "Surfactant-Assisted Zerovalent Iron Dechlorination Of Polychlorinated Biphenyl In Contaminated Sediment." Electronic Thesis or Diss., Université de Lorraine, 2016. http://www.theses.fr/2016LORR0066.
Soil and sediment contamination by polychlorinated biphenyls (PCBs) is a global health and environmental concern, since PCBs are toxic and recalcitrant. The aim of this thesis is to find a remediation process to PCBs contaminated sediments by using zerovalent iron (ZVI). To begin the studies on remediation, a survey was conducted on sites contaminated by e-waste recycling activities in south China. PCBs contamination was not as severe as previously, whereas the co-existence of PCBs and heavy metals increases the difficulty of remediation. Afterwards, the feasibility PCBs degradation by ZVI in aqueous solutions was investigated. Results confirmed the stepwise dechlorination of PCBs by ZVI and the major pathway with congener specifity and regiospecifity. The relative importance of the influential factors to ZVI degradation of PCBs was in the order of surfactants > humic acid > pH > Ni2+. Sediment decontamination was studied by 1) washing with an aqueous solution of surfactant followed by ZVI dechlorination of PCBs and 2) direct mixing with ZVI and surfactant solution. The second approach gave promising results for remediation

The bauxite residue commonly called ‘red mud’ is an industrial waste generated during the production of alumina. The storage of this waste is considered as a major environmental problem, especially because of its caustic nature (pH> 10) and the huge produced quantities (about 1.5 t per tonne of alumina produced). The production of Venezuelan alumina (CVG Bauxilum) has generated more than 15 million m3 of bauxite residue. Moreover, no research has yet been conducted on the properties of these residues and their utilization in the environmental field. The main goals of this study focus on the physical and chemical characterization of Venezuelan bauxite residue (solid fraction) and in an evaluation of its applications as an agent for remediation of polluted systems. An integrated approach coupling chemical composition and adsorption properties, mineralogical phases, particle size, surface area and radionuclide content with studies of chemical speciation and bioavailability, yielded significant constraints including: 1) a high content of U and Th, and their respective isotopes Th232 and U238, as well as lanthanides 2) the potential risk of residue chemotoxicity towards a very labile fraction of elements such as aluminum and uranium 3) high sorption properties with respect to toxic elements, Pb, Zn and As, due to the large surface area of the residue, especially under acidic conditions (case of acid mine drainage). These results have shown the potential use of Venezuelan bauxite residue in key areas such as remediation of polluted systems (as amendment or sorbent agent) and in the recovery of metals of economic interest
