大中型污水处理厂建设过程应用海绵设施的设计研究

Study on the Design of Sponge Facilities Used in the Construction of Large and Medium-sized Sewage Treatment Plants

在一些大型污水处理厂中易出现污水排放不合规,污水处理不及时形成积水的现象。因此,对某市的功能区域进行污染度分析,从工厂内和工厂外两方面分析污水中污染物来源。根据地面高度、道路坡度、总体平面布局、道路高度以及厂区场地控制和管线布局,将其分为十九个区域。对区域内调蓄容积进行计算,在计算前所有准备工作均按照城市排水规划施工标准来进行。最后根据实际降水情况和具体调蓄容积进行合理海绵排水。通过工程实施,对该工程内各区域污染控制和分区污染物去除率进行记录,结果均效果良好且符合海绵城市规划标准。

In some large sewage treatment plants,it is easy to appear sewage discharge is not compliant,sewage treatment is not timely formation of water phenomenon.Therefore,the pollution degree analysis of the functional area of a city is carried out to analyze the sources of pollutants in sewage from both inside and outside the factory.According to the ground height,road slope,overall layout,road height,site control and pipeline layout of the plant,it is divided into 19 areas.The storage capacity in the area is calculated,and all the preparatory work before calculation is carried out in accordance with the urban drainage planning and construction standards.Finally,sponge drainage is carried out reasonably according to the actual precipitation situation and the specific storage volume.Through the implementation of the project,the pollution control and the removal rate of regional pollutants in the project were recorded,and the results were good and in line with the sponge city planning standards.
