The d is2tributing status and monitoring request of dra in ingwater pipe network in Zhenjiang are introduced, inclu2d ing sewage pump ing station, system composition, data processing of rea l2timemon itor and automatic con2trol system. Thewire less transmission mode ofmon itoring data, the characteristics ofGPRS wireless trans2mission system, the selection of equ ipment on linemonitoring instruments, and the real2time d isplay princi2p le of themon itoring system data are a lso introduced. Through the analysis, it shows thatGPRS is particu2larlywell suited to the communication between those data collected inmonitoring points and center comput2er. The system of rea l2timemon itor and the automatic controlmay realize the observation for sewage dispos2al data all day and find out the real2time changes of data, for examp le, pH value, the flux, andwater lev2e.l The observation result ind icate that the illegal d ischarge of sewage with strong acid and alkali into theurban sewage pipe network, the pump ing station, as we ll as sewage treatment plants fac ilitywill affect thesewage treatmentmicro2organism activeness and reduce the sewage treatme
