Multi-stage sewage interception rainwater discharge outlet for controlling urban rainwater surface source pollution
The invention discloses a multi-stage sewage interception rainwater discharge outlet for controlling urban rainwater surface source pollution. The multi-stage sewage interception rainwater discharge outlet comprises a box culvert, first-stage filter walls, second-stage filter walls, longitudinal guide walls and transverse guide walls; a water inlet hole is formed in the front face of the box culvert and connected with a discharge outlet of a rainwater pipe; the longitudinal guide walls and the transverse guide walls which are through in top are arranged in the box culvert and arranged in a T shape; the distance between the transverse guide walls and the inner walls of the two sides of the box culvert is one time of the pipe diameter, and the thickness of the transverse guide walls ranges from 100mm to 200mm; and the first-stage filter walls with the width equal to that of the overflowing section are additionally arranged at the two ends of the transverse guide walls. The multi-stage sewage interception rainwater discharge outlet has the advantages that impact pollution caused by urban rainwater runoff to receiving water is reduced, and water resources are effectively supplemented; the occupied area is small, the outflow capacity is high, and the concealment is good; and no power is consumed in the running process, and therefore the comprehensive project investment is small, the operation cost is low, the water quality impact load resistance of a system is high, operation is easy, and maintenance is easy.
本发明公开了一种控制城市雨水面源污染的多级截污雨水排放口，包括箱涵、一级滤墙、二级滤墙、纵向导流墙、横向导流墙，所述箱涵前面开设进水孔，并与雨水管的排口连接；所述箱涵内设置通顶的纵向导流墙和横向导流墙，横向导流墙和纵向导流墙互呈T形排布，其中横向导流墙距箱涵两侧内壁均为1倍管径，厚度100~200mm；在横向导流墙两端，加设与过流断面等宽的一级滤墙。本发明的技术效果和优点：削减城市雨水径流对受纳水体造成的冲击性污染，也是水资源的有效补充。占地面积小、出流能力强、隐蔽性好。运行无动力消耗，因此综合工程投资较少，操作成本低，系统抗水质冲击负荷强、操作简单，容易维护。
