针对UV/H2O2工艺出水残留大量H2O2，且可能导致消毒副产物(DBPs)前驱物增多等特点，拟采用生物活性炭（BAC）作为UV/H2O2的后续工艺，猝灭出水残余H2O2的同时，控制DBPs的生成。根据微生物的生长状况，将BAC划分为催化区与生物区，研究其对DBPs的控制机制，主要内容包括：考查残余H2O2与催化区活性炭对DBPs的联合控制机制，以及各因素对催化区DBPs控制效果和吸附容量的影响机制；研究催化区对生物区的影响机制，催化区与生物区对DBPs的联合控制机制，以及各因素对生物区DBPs控制的影响机制；探讨特征污染物在催化区和生物区的转化特性，阐明BAC工艺对DBPs前驱物的转化机制，为该工艺对DBPs的控制提供理论基础；以实际水样为对象，评估UV/H2O2-BAC对DBPs的控制作用及经济成本，找到主控因子并提出相应的防控策略。本项目将对UV/H2O2工艺实践起到积极推动作用。

Effluent from UV/H2O2 process contains abundant residual H2O2 and it may increase the precursor contents of disinfection by-products (DBPs). In this research, biological activated carbon (BAC) would be applied following UV/H2O2 process to quench the residual H2O2 and control the DBPs formation. According to the living status of microorganisms, BAC would be divided into two parts: the catalysis and biota part, and the mechanism of DBP control for these two pars would be studied. The main contents were as followed: the combined control mechanism of DBPs by residual H2O2 and activated carbon in the catalysis part, and the influencing mechanism of different factors on the control effect of DBPs and adsorption capacity would be examined; The influencing mechanism of the catalysis part on the biota part, the combined control mechanism of DBPs by the catalysis and biota part, and the influencing mechanism of different factors on the control effect of DBPs by the catalysis and biota part would be studied; The transformation characteristics of selected pollutants in the catalysis and biota part would be discussed, and the transformation mechanism of DBP precursors in the BAC process would be researched, providing a fundamental basis for the DBPs control by BAC; A practical water sample would be applied to assess the control effect of DBPs by UV/H2O2-BAC and its economic cost. Based on these studies, the main control factor would be demonstrated, and a strategy for the DBP control would be suggested. This study would promote the practice in UV/H2O2 area.
