| 摘 要： | 城市降雨径流污染对水环境造成严重危害，市政雨水口作为收集雨水的构筑物，可以改造为源头截污设施。试验采取雨水口增设截污网篮的形式，对雨水口进、出水进行了采样检测，分析结果表明:径流雨水中污染物成分复杂，在雨季初期及降雨间隔时间较长的情况下，径流污染负荷尤为明显。截污装置以物理截留功能为主，对SS去除效果较好，场降雨平均去除率为54.5%，对COD、可滤残渣等污染物的去除效果相对较差。截污装置作为一种简易净化措施，可以应用于新建、改建及扩建地区的市政雨水口，起到控制径流污染、缓解黑臭水体的功能。

| Abstract: | Urban runoff pollution has caused serious problems to the water environment. As a structure for collecting runoff, municipal inlet can be transformed into pollution interception facilities at the source. The test added a pollution interception net basket to the grate inlet, and sampled the influent and effluent of grate inlet from rainfall events. The results showed that the composition of runoff pollutant was complex. In the beginning of rainy season and when the interval was long, the pollution load of runoff was particularly serious. The removal device was mainly based on physical interception, the removal efficiency of SS was better,the average removal efficiency was 54.5%, and the removal efficiency of COD and other pollutants was relatively lower. As a simple purification measure, the decontamination device could be applied to the municipal water outlet in the newly built, rebuilt and expanded areas, and play a role in management of runoff pollution and black and odor water bodies. |
