摘要
通过对山东省某县级市城区污水总干管流量检测和分析表明:实测总变化系数Kz=1.255,与《室外排水设计规范》(GB 50014—2006)计算的污水总变化系数Kz′=1.301相差不大.进一步对10,5,1 min的污水峰值流量进行了调查分析,发现污水流量在峰值的最大小时内,有较大的波动,这样的波动对于污水管渠和污水厂的运行有较大的影响.
Through measuring the flow in the main sewage pipe of a county-level city in Shandong Province and analyzing the data,the test shows that the measured total changing factor Kz= 1.255 is not too different from the values of sewage total changing factor K′z=1.301 calculated according to the Outdoor Drainage Design Specifications（GB 50014—2006）.This paper further investigates and analyzes the 10,5 and 1 min peaking flow.It finds out that sewage flow has the greatest fluctuation in the peaking value of the largest period of time.This fluctuation has great effect on the running of sewage drainage pipes and sewage treatment plants.
