武汉汉口地区污水系统流量调查分析及对策研究

Investigation of Sewage System Quantity in Hankou District of Wuhan City and Its Countermeasures

为解决武汉汉口地区污水处理厂进水浓度偏低、泵站运行负荷不均衡、部分污水溢流到排水明渠导致水体黑臭等问题,对汉口地区污水收集及处理系统现状进行全面调研,考察污水量的分布特点及其成因。调研发现,汉口地区各污水系统间存在多个连通点,进一步对子系统边界的连通点进行测流并重新划分汇水范围线,修正污水量计算后提出了污水调配和排水系统规划调整的建议。另外,对地下水渗入量和施工排水量也进行了探讨,提出了施工排水的解决方法。

A comprehensive investigation on present situation of sewage collection and treatment system was conducted in Hankou District of Wuhan City, and the distribution characteristics of sewage and the causes were analyzed, which desired to solve the problems such as low influent concentration in wastewater treatment plants in Hankou District, unbalanced loads of pumping stations, black and odorous water body induced by sewage overflow discharges, and so on. It was found that there were multiple connectivity points between the sewage subsystems in Hankou District. The boundary points flow rate of the sewage subsystems was further measured,and new catchment boundaries were divided. Based on these results, the sewage quantity was recalculated, and suggestions of sewage distribution adjustment and drain- age system planning adjustment were proposed. Moreover, capacity of groundwater infiltration and construction drainage was also investigated, and the solution of construction drainage was put forward.
