海绵城市污水处理措施及对城市环境的改善研究

Sponge City Sewage Treatment Measures and Urban Environment Improvement

海绵城市合流制溢流污是污水处理最严重的问题,直接影响城市水环境,为人们生活与生产带来威胁,为此提出海绵城市污水处理措施及对城市环境的改善研究。海绵城市污水处理措施为:一是合流制管道改造。利用推理公式法确定截流倍数,以此为基础,控制污水溢流量;二是调蓄池建设。为降低污水溢流量,在合流管截流井处与污水厂溢流井前建设调蓄池。选取某生态城作为实验区域进行仿真模拟实验。仿真实验结果表明,提出措施调蓄池进水量与污水溢流量更低,具备更好的应用效果。

Sponge city combined overflow sewage is the most serious problem of sewage treatment,which directly affects the urban water environment and threatens people’s life and production.Therefore,sponge city sewage treatment measures and research on the improvement of urban environment are proposed.Sponge city sewage treatment measures are as follows:One is the transformation of combined pipelines.Use the reasoning formula method to determine the interception multiple,and control the overflow of sewage based on this;the second is the construction of the storage tank.In order to reduce the overflow of sewage,a storage tank shall be constructed at the junction interception well and in front of the overflow well of the sewage treatment plant.Select an eco-city as the experimental area for simulation experiments.The simulation experiment results show that the proposed measures have lower water intake and sewage overflow in the storage tank,and have better application effects.
