摘　　要：根据地区污水处理设施旱季是否有余量,分析了改造截流设施(增大堰高、槽深或截流管管後)直接提高截流倍数和增加调蓄设施间接提高截流倍数两种截流方案的优劣。同时,提出了溢流频次与溢流控制率分析计算流程,为截流设施建设、改造提供指导和建议。针对混接问题.分析了各地区混接现状与混接问题治理方案,对比了源头截流与末端截流的优劣,提出了治理混接问题的建议。According to the local sewage treatment facilities remaining treatment capacity of the dry season,this paper analyzes the advantages and disadvantages of the two intercepting schemes, including increasing the height of the weir, the depth of the trough or the diameter of the intercep ting pipe to directly increasing the interception ratio, and increase the storage facilities to indirectly increase the intercepting ratio. Meanwhile, we propose the analysis and calculation process of over flow frequency and overflow control rate, and provide guidance and suggestions for the construction and reconstruction of the intercepting facilities. In view of non-stormwater entries into storm drain age problem, we analyzes the current situation and treatment plan of each region, compares the merit and demerit of source interception and end interception, and puts forward some suggestions for governance the problems.
