某区域集中污水处理厂在运行过程中出现出水水质不稳定，活性污泥中毒，处理效率下降等现象。首先阐述了该污水处理厂以及收集区内重点污染源的基本情况，从在线监测设备和工艺设施的配备以及实际水质与设计水质的偏差等方面分析了造成出水不达标的原因。并从源头控制、过程监控、末端处理3个方面提出改进措施，重点强调了水质在线监控在污水处理厂日常运行中的重要性以及相关监测设备的选用，同时指出水质毒性监测应成为在线监测的重点。

There was activated sludge poisoning, efficiency decreasing, water quality instability in operation of a regional centralized sewage plant. The basic situation of the plant and major pollution sources in collection area were introduced at the beginning. The reasons why water quality could not meet relative standard were analyzed from online monitoring equipment, process facilities and the deviation of actual and designed water quality. This article also put forward the improvement measures from inlet control,process monitoring and terminal treatment,among which the function of water quality monitoring in the operation of sewage plant and the selection of related equipment were especially emphasized.The water toxicity detection was considered as the focus of online monitoring.
