摘要
探讨了城市排水监测方法及在线监测系统开发的必要性.介绍了镇江市排水管网和污水泵站的分布情况和监测要求,以及镇江市实时监测和自动控制系统的组成、数据处理情况;介绍了监测数据的无线传输方式,即GPRS无线传输系统的特点;介绍了在线监测仪器仪表等设备的选用情况.介绍了监测系统数据的实时显示原理.通过分析表明,GPRS尤其适用于各监测点所采集的数据与中心主机的通信.该市实时监测和自动控制系统可以实现全天候观测污水排放数据,了解pH值、流量、水位等数据的实时变化.通过该系统对部分重点排污企业监控点进行的观测结果表明,强酸强碱污水的偷排,不仅对城市排水管网、泵站以及污水处理厂的设施产生腐蚀危害,还会影响污水处理微生物的活性,降低污水处理能力.
The urban drainage monitoring method and the online monitoring system are discussed. The distributing status and monitoring request of draining water pipe network in Zhenjiang are introduced, including sewage pumping station, system composition, data processing of real-time monitor and automatic control system. The wireless transmission mode of monitoring data, the characteristics of GPRS wireless transmission system, the selection of equipment online monitoring instruments, and the real-time display principle of the monitoring system data are also introduced. Through the analysis, it shows that GPRS is particularly well suited to the communication between those data collected in monitoring points and center computer. The system of real-time monitor and the automatic control may realize the observation for sewage disposal data all day and find out the real-time changes el. The observation result indicate that the illegal of data, for example, pH value, the flux, and water levdischarge of sewage with strong acid and alkali into the urban sewage pipe network, the pumping station, as well as sewage treatment plant＇s facility will affect the sewage treatment micro-organism activeness and reduce the sewage treatment ability.
