摘　　要：主要介绍化学生物絮凝工艺的自动控制系统,以TP为目标通过对控制加药系统中药剂和磷酸盐反应摩尔数MR和廊道曝气量这两个参数的优化,使自动控制系统针对不同水质及时采取相应的措施,优化系统的污染物去除能力。实验表明在MR=2.0时,化学生物絮凝工艺处理上海市城市污水能够保证处理后出水的TP平稳达标排放。设置各廊道DO上下浓度为:第一格DO,2～3mg/L;第二格DO,2～4mg/L;第三格DO,0～1.0mg/L,不仅实现对污染物的稳定去除,而且提供生物絮凝所需的水力条件,使出水SS得到良好控制。Chemical biological flocculation auto-control system was introduced in this paper. MR （mole number of reaction） of reagent adding process in TP control system and channel aeration quantity are two important parameters, through the optimization of which auto-control system can take proper measurement to optimize the ability of treating contaminants according to different wastewater. When MR=2.0, sewage of Shanghai can meet the discharge standard stably after the chemical biological flocculation process. Setting DO at the range of 2-3 mg/L, 2-4 mg/L and 0-1.0 mg/L respectively in three galleries can not only reach the stable removal of contaminants but also guarantee the hydrodynamic condition for biological flocculation to ensure the effluent SS under control.
