随着世界范围内对水资源的需求和压力不断增加，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。在这一主题下，根据申请人正在进行的既定研究计划，拟议研究的主要目标是开发具有成本效益的深度处理技术，用于从水和废水污泥(生物固体)中去除微污染物，用于水的再利用和从生物固体中回收资源。这项研究将涉及应用高级氧化工艺(AOP)，如UV、UV/H_2O_2和UV/O_3，它们会在现场产生羟基自由基，用于从水和污泥中去除模型微污染物，开发基于生物测试的有效和快速的程序，以确定在高级氧化处理的不同阶段微污染物及其降解产物的毒理效应。科学方法将包括分析微污染物及其降解产物，确定微污染物的降解动力学和机理，确定各种AOP预处理污泥在厌氧消化中的性能，以及应用生物测试，如对各种流出物的雌激素活性和诱变性。将进行彻底的经济分析，以确定目标化合物的合适处理方案。拟议的研究将培训3名博士生和2名硕士研究生，并将分享申请者实验室为目标微污染物开发的通用分析设施和方案，以提高小组的生产力。作为拟议研究的成果，从生物固体中去除微污染物用于水再利用和资源回收的具有成本效益的处理技术有望实现商业化。在该项目中培训的HQP将接触到复杂的化学和分析方法、动力学建模和微生物程序。

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.
