【摘要】 针对目前生化尾水处理中内分泌干扰毒性（EDCs）深度削减技术较少，常规氯消毒会增加生物毒性、提高运行成本且操作复杂，将生化处理和催化臭氧氧化处理技术结合，提出用于生化尾水EDCs深度削减及安全回用的方法，结合小试试验结果和示范工程，构建“功能菌强化膜生物反应器（MBR）+臭氧催化氧化”工艺用于生化尾水EDCs的深度削减。结果表明，出水中EDCs削减率为84.51%,EDCs平均质量浓度为0.8 ng/L（以雌二醇计），出水满足EDCs安全阈值的要求和生化尾水的安全排放与回用要求，可为今后市政污水的安全排放与回用提供参考。更多还原

【Abstract】 At present,there are few deep reduction technologies for endocrine disrupting toxicity(EDCs) in biochemical tailwater treatment,and conventional chlorine disinfection will cause increased biological toxicity,high operating cost and complex operation.In this paper,combining biochemical treatment with catalytic ozone oxidation treatment technology,a method for deep reduction and safe reuse of biochemical tail water endocrine disruption toxicity was proposed.Combined with pilot test results and demonstration projects,a process of“functional bacteria enhanced MBR+ozone catalytic oxidation”was constructed for deep reduction of endocrine disruption toxicity of biochemical tail water.The experimental results showed that the reduction rate of endocrine disruption toxicity in effluent water was 84.51%,and the average concentration was 0.8 ng/L,and the effluent met the requirements of the safety threshold of endocrine disruption toxicity and the safe discharge and reuse of biochemical tail water,it provides reference for the safe discharge and reuse of municipal sewage in the future.更多还原
