摘　　要：针对西安市第四污水处理厂倒置A2/O工艺实际运行除磷效果差、出水TP不能达标排放的问题,通过监测污水处理厂实际进出水水质和生化反应池运行参数,分析除磷效果差的主要原因,并研究其解决措施,寻求最优的运行参数和工程改造措施,提出优化厌氧区水力停留时间、强化污泥处理系统污泥水的处理,以及启动污水处理厂已建成的化学除磷系统等措施。According to the problems in the practical operation of reversed A2/O process in Xi＇an the Forth Wastewater Treatment Plant,such as low phosphorus removal effect,effluent TP not meeting the discharge standards,and so on,based on the monitoring of practical influent water quality and bio-chemical reaction tank operation parameters in wastewater treatment plant,the authors analyzed the main reasons for the low phosphorus removal effect and studied the measures,investigated the optimized operation parameters and process reconstruction measures,brought forward the measures,such as optimized anaerobic zone water residence time,enhanced sludge water treatment in sludge treatment system,and inactivation of the built chemical phosphorus removal system in the wastewater treatment plant,which could offer references for the optimized design and operation of the similar wastewater treatment plants in the future.
