AI Technical Summary
Technical Problem
值得注意的是，初期雨水中含有大量污染物，其污染程度有时甚至超过一般的城市污水，这无疑对水环境造成了不容忽视的污染
Benefits of technology
[0015]本实用新型提供的一种雨水截留系统的有益效果在于：与现有技术相比，本实用新型一种雨水截留系统，采用了“液位联动阀门”的机械控制逻辑，无需复杂电气设备，大幅简化了设计流程、降低了多专业协同的难度，减少了设计与施工成本；针对传统截流井“无法区分初期与后期雨水、导致初期雨水污染水环境”的问题，通过雨水收集池的“存储-满溢”机制，自动实现初期雨水（进雨水收集池）与后期清洁雨水（进市政水管网）的分离，初期雨水含大量污染物，被收集后可集中处理利用，避免直接排放污染水体，后期清洁雨水直接排入市政管网，既保障了水环境质量，又符合“初期截污、后期排涝”的雨水管理需求；同时减少了初期雨水的地表径流，降低了城市内涝风险，满足海绵城市的建设需求。
