Municipal road initial rainwater collecting device

Abstract

The invention relates to a municipal road initial rainwater collecting device, and relates to the field of municipal rainwater treatment devices, the municipal road initial rainwater collecting device comprises a drainage ditch and a water collection pool, a primary filtering device and a secondary filtering device are arranged in the drainage ditch, the secondary filtering device is located below the primary filtering device, and a rainwater purification device is arranged in the water collection pool. A water purifying tank is dug between the drainage ditch and the water collection pool, a cleaning turntable is rotatably connected in the water purifying tank, the surface of the cleaning turntable faces the pipe orifice of a water outlet pipeline, and a flocculation device and a sediment removing device are arranged on the cleaning turntable. The device has the effects of reducing the pollution degree of rainwater to rivers and reducing the damage to the environment.

Description

technical field [0001] The present application relates to the field of municipal rainwater treatment devices, in particular to an initial rainwater collection device for municipal roads. Background technique [0002] The initial rainwater often dissolves the acid gas in the air, factory exhaust gas, automobile exhaust and other polluting gases. After it falls to the ground, it will wash away the roof and asphalt concrete roads, etc., so that the initial rainwater contains many organic pollutants and heavy metals, etc., and Rainwater will carry a large amount of road garbage, which is directly discharged into the river, causing a certain degree of pollution to the river. Therefore, it is necessary to collect and treat the initial rainwater before discharging it into the river. [0003] In related technologies, refer to figure 1 The initial rainwater collection device of the political road includes a drainage ditch 1 dug on the road surface, a grid plate 2 laid on the drainag...

AI Technical Summary

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that although the above-mentioned collection device can intercept the pollutants in the rainwater to a certain extent, there are various types of impurities in the rainwater, and the decontamination effect of the rainwater is very poor only by the filter screen interception. , resulting in more rainwater impurities collected in the sump. At this time, such sewage discharged into the river will still pollute the river and damage the environment.
