Rainwater collecting and purifying facility
The invention relates to the technical field of urban rainwater treatment, and in particular relates to a rainwater collecting and purifying facility. The facility comprises a rainwater collection pipe, a filter tank, a water outlet pipe and a surface flow wetland, wherein the rainwater collection pipe, the filter tank and the water outlet pipe are arranged under the road surface of a waterfront area, and the surface flow wetland is arranged on the river channel edge of a waterfront area; the filter tank is provided with an inlet connected with the rainwater collection pipe, an outlet connected with the water outlet pipe and a filter part arranged between the inlet and the outlet; the rainwater collection pipe introduces surface rainwater into the filter tank, and the surface rainwater isfiltered by the filter part and then conveyed to the surface layer of the surface flow wetland through the water outlet pipe. Surface rainwater can be led into the filter tank through the rainwater collection pipe, particles and pollutants with large granularity are filtered out and then conveyed to the surface layer of the surface flow wetland through the water outlet pipe, the surface rainwaterflows through the surface layer of the surface flow wetland and then enters riverway water flow, the surface flow wetland can play a role in biological purification of the surface rainwater, and meanwhile the surface flow wetland has the water seepage and storage functions. Therefore, the rainwater collecting and purifying facility realizes purification of rainwater entering a river and a sponge function.
本发明涉及城市雨水处理技术领域，尤其涉及一种雨水收集净化设施，包括设于滨水区路面下的雨水收集管、过滤池和出水管以及设于滨水区河道边缘的表流湿地，过滤池设有与雨水收集管相连接的入口、与出水管相连接的出口以及设于入口与出口之间的过滤件；雨水收集管将地表雨水引入过滤池中，地表雨水经过过滤件过滤后通过出水管输送至表流湿地的表层。地表雨水可由雨水收集管引入过滤池中，过滤掉颗粒度较大的颗粒物和污染物后通过出水管输送至表流湿地的表层，流经表流湿地表层后再进入河道水流中，表流湿地能够对地表雨水起到生物净化的作用，同时还具有渗水蓄水功能。由此，该雨水收集净化设施实现了入河雨水的净化以及海绵功能。
