雨污分流排水体制是一种比较合理的排水体制,但该体制中雨水系统的污染仍然非常严重。提出了分散调蓄截流方案和分散独立截流方案,介绍了各方案的主要内容、分类及适用条件,探讨了各方案的运行控制思路及参数选取。两方案在设计合理、施工达标及管理到位的情况下,均可有效地控制雨水排放系统的污染。 Rainwater and sewage diversion drainage system is a more reasonable drainage system, but the system of pollution of the rainwater system is still very serious. Proposed a decentralized storage and interception plan and decentralized independent interception plan. The main contents, classification and applicable conditions of each plan were introduced. The operational control ideas and parameter selection of each plan were discussed. The two schemes can effectively control the pollution of the stormwater discharge system under the conditions of reasonable design, construction compliance and management.
