With the increasing world-wide demand for and pressure on water resources, new technologies and more cost effective solutions are needed for conservation and management of water resources. Under this theme and in accordance with the established on-going research program of the applicant, the principal objective of the proposed research is to develop cost effective advanced treatment technologies for micropollutant removal from water and wastewater sludge (biosolids) for water reuse and resource recovery from biosolids. The research will involve the application of advanced oxidation processes (AOP) such as UV,UV/H2O2 , and UV/O3, which produce hydroxyl radicals in-situ for the removal of model micropollutants from water and sludge, develop effective and rapid procedures based on bioassay tests to determine toxicological effects of micropollutants and their degradation products at various stages of advanced oxidative treatment. The scientific approach will involve analysis of micropollutants and their degradation products, determination of kinetics and mechanism of degradation of the micropollutants, establish the performance of various AOP pretreated sludge in anaerobic digestion, and application of the bioassay tests such as estrogenicity and mutagenicity for various effluents. A thorough economic analysis will be conducted to determine the suitable treatment option for a target compound. The proposed research will train 3 Ph D and 2 Masters students, and will share the common analytical facilities and protocols for target micropollutants developed in the laboratory of the applicant enhancing the productivity of the group. As an output of the proposed research, cost effective treatment technologies for the removal of micropollutants for water reuse and resource recovery from biosolids can be expected for potential commercialization. HQP trained in this project will be exposed to sophisticated chemical and analytical methods, kinetic modeling, and microbiological procedures.

随着世界范围内对水资源的需求和压力的增加，需要新技术和更具成本效益的解决方案来保护和管理水资源。根据这一主题，并根据申请人已建立的正在进行的研究计划，拟议研究的主要目标是开发具有成本效益的先进处理技术，用于从水和废水污泥（生物固体）中去除微污染物，用于水的再利用和生物固体的资源回收。该研究将涉及高级氧化工艺（AOP），如UV，UV/H2 O2和UV/O3的应用，这些高级氧化工艺原位产生羟基自由基用于去除水和污泥中的模型微污染物，开发基于生物测定试验的有效和快速程序，以确定微污染物及其降解产物在高级氧化处理的各个阶段的毒理学效应。科学方法将涉及分析微污染物及其降解产物，确定微污染物降解的动力学和机理，确定各种AOP预处理污泥在厌氧消化中的性能，以及应用生物测定试验，如各种流出物的雌激素和致突变性。将进行全面的经济分析，以确定目标化合物的适当治疗方案。拟议的研究将培训3名博士和2名硕士生，并将共享申请人实验室开发的目标微污染物的通用分析设施和协议，以提高小组的生产力。作为拟议研究的一项产出，可以预期用于去除微污染物以进行水再利用和从生物固体中回收资源的具有成本效益的处理技术具有潜在的商业化潜力。在本项目中接受培训的HQP将接触复杂的化学和分析方法、动力学建模和微生物程序。
