摘　　要：以湖北省某生活污水和制药废水混合进水污水处理厂为例,结合生产实践,分析该污水处理厂生化工艺运行存在的主要问题与原因,并提出针对性建议。通过流程采样分析和活性污泥耗氧速率测试,发现该污水处理厂水解酸化池存在过度降解可生化性有机物、氧化沟污染物去除效率低、污泥活性低等问题。通过深入调研与分析,提出缩短水解酸化池水力停留时间、增加生物处理系统排泥等优化措施。研究成果可为污水处理厂优化工艺运行管理、挖潜和提质增效提供决策依据。The major problems and causes of the biological treatment in a wastewater treatment plant(WWTP)in Hubei Province are analyzed as a case study,and targeted suggestions are put forward.The influent of the WWTP is composed of domestic sewage and pharmaceutical wastewater.Through process sampling analysis and activated sludge oxygen consumption rate test,we found excessive degradation of biodegradable organic matter in the hydrolysis acidification tank and low pollutant removal efficiency as well as low sludge activity in the oxidation ditch.We propose to shorten the hydraulic retention of hydrolysis acidification tank and increase the sludge discharge of biological treatment system.The research is expected to provide decision-making basis for optimizing process operation management and improving efficiency.
