苏州市古城区初雨治理方法探索

Exploration of initial rainwater treatment in old town district of Suzhou

对于古城区,构筑物密度高,道路窄,地下管线密集,绿地面积少等情况造成常规的海绵设施缺乏足够的建设用地进行大面积建设。结合苏州古城区的特点,通过在古城区现状零星合流制区域设置截留设施,改造现状雨水泵站两种方式来治理初雨。

In old town district,there is no sufficient construction land for conventional sponge facilities because of high structure density,narrow roads,dense underground pipelines,less green space.In this paper,combined with the characteristics of Suzhou old town district,the interception facilities will be set up in the sporadic combined system area,and the rainwater pumping station will be modified to carry out regional initial rain treatment.Preliminary study on the initial rainwater pollution control in Suzhou old town district is to prepare for the further project.
