specific Embodiment

[0044] A specific embodiment of the present invention is as follows:

[0045] According to the terrain of the lakeside area, the integrated system of rainwater collection, diversion and ecological purification with a slope of 1% is arranged to collect the rainstorm runoff in the polluted area of ​​1.86 hectares without energy consumption. and then into the rainwater distribution well 4. The rainwater collecting pipe 2 is provided with water inlet holes with a diameter of 25mm at 45° from the center of the pipe on both sides of the lower part every 200mm, and the interception ditch outside the rainwater collecting pipe 2 is filled with gravel with a particle size of 30-50mm.

[0046] The length, width and height of the rainwater diversion well 4 are 1.0m*1.0m*1.2m, the length, width and height of the rainwater adjustment pond 8 are 60.0m*5.0m*1.0m, and the effective volume is 150m 3 , used to store the initial 20-minute storm runoff from the contaminated area.

[0047] The sm...

Abstract

The invention relates to an early stage rain-water collecting and diverting ecological purification integrated system used for lakesides, laying rain-water collecting pipe and filling ecological gravels in the rain-water entrapment trench, The water collected by the collecting pipe is transported into rain-water diverting well, diverting the water by the inlet pipe and outlet diverting pipe with the same height and diameter, and than transferred to four grade artificial wetland of 'coarse gravel-zeolite-functional stuffing-fine gravel' for stage ecological purification by adjusting the cloth water pipe laid on the bottom, and transported into lake again after purification. The invention can purify the heavily polluted early stage hard rain without effecting the ecological landscape.

Description

technical field [0001] The invention relates to an integrated system for collecting, diverting and ecological purification of initial rainwater in the lakeside area, which collects the rainstorm runoff generated in the polluted area of ​​the lakeside area, and separates the more seriously polluted initial rainstorm runoff from the later less polluted rainstorm runoff, and adopts four methods The first-grade constructed wetlands purify the collected initial rainwater. The invention belongs to the technical field of artificial wetland sewage treatment. Background technique [0002] In recent years, frequent human activities and high-intensity development have brought huge economic benefits to the city around the urban lakeside area, but also brought negative effects to the ecological environment of the lake. The non-point source pollutants produced in the watershed around the lake will be directly brought into the water body along with the rainstorm runoff, causing the nitrog...
