初期雨水水质水量在线监测系统优化及初步应用

Optimization and Preliminary Application of Initial Rainwater On-line Monitoring System

以苏州河沿岸修建了调蓄池的合流制和分流制两个排水系统为研究对象,构建了自动化水质水量在线监测及远程控制系统。针对该系统在运行过程中存在的不足,从进水单元、监测指标、分析仪表、采样模式、系统安全、统计分析等方面进行了优化,并扩展运用到污水输送干线调蓄池所在系统。优化的初期雨水水质、水量在线监测系统在排水系统背景水质、降雨初期径流水质、降雨径流过程监测及初雨调蓄减排环境效应统计等方面均得到了较好的应用效果。

Based on deficiencies of the automatic on-line water quality monitoring and remote con- trol systems for combined sewerage system and separate sewerage system with storage tanks along Suzhou Creek, the systems were optimized in aspects of the water inlet unit, the monitoring indexes, the analysis instruments, the sampling mode, the system security, the statistical analysis and so on, and applied to the sewerage system with storage tanks in the main sewer. The results of application showed that the opti- mized systems could be well used in several fields such as monitoring of dry weather flow quality, initial rainwater quality and rainfall runoff process and assessment of discharge reduction and environmental ben- efits.
