Municipal drainage system

Abstract

The invention relates to a municipal drainage system. The municipal drainage system comprises a municipal pipeline for drainage, and further comprises a rainwater collecting tank built below a lawn, wherein the rainwater collecting tank is formed by enclosing concrete partition walls around the rainwater collecting tank; an opening is formed in the upper portion of the rainwater collecting tank, and a plurality of groups of cross beams and longitudinal beams which are used for supporting are arranged at the opening end of the rainwater collecting tank; a filtering layer, a soil layer and a planting layer are arranged above the cross beams and the longitudinal beams; a drainage pipeline which communicates with the upstream of the municipal pipeline is arranged below one side of the rainwater collecting tank; a valve for opening and closing the drainage pipeline is arranged in the rainwater collecting tank; and a driving piece for opening and closing the valve according to the water level is further arranged in the rainwater collecting tank. The municipal drainage system has effects of collecting rainwater for flushing the municipal pipeline, reducing sediment in the municipal pipeline, thus reducing pollution discharge treatment work of municipal workers and effectively saving the cost.

Description

technical field [0001] The invention relates to the technical field of municipal facilities, in particular to a municipal drainage system. Background technique [0002] As we all know, the municipal drainage system is a system dedicated to the discharge and cleaning of rainwater, domestic sewage and industrial wastewater, which is widely used in municipal work; , Domestic sewage and industrial wastewater are collected in a centralized manner, and sedimentation and purification are carried out through sedimentation tanks; in the use of this municipal drainage system, it is found that industrial sewage is more harmful, so it is mixed with rainwater and domestic sewage and discharged into the river. cause deeper pollution. [0003] The existing authorized announcement number is a Chinese patent of CN205975900U, which opens a municipal drainage system, including a rainwater collection tank, a first pipeline, a second pipeline, a domestic sewage collection tank, a third pipeline...

AI Technical Summary

Problems solved by technology

[0005] The above-mentioned existing technical solutions have the following defects: although the separate treatment of rainwater, domestic sewage and industrial wastewater helps to protect the environment; but in the process of rainwater discharge, after the rainwater is purified by the activated carbon box, it is directly It is undoubtedly a waste to discharge into the river

In the usual municipal drainage process, since the rainwater or sewage contains particulate matter or other sediments, the water flow of the municipal drainage is not enough to discharge the sediment directly, resulting in staying in the municipal pipes, causing the possibility of blockage; therefore, frequent municipal Workers, sewage treatment of municipal pipelines, resulting in a certain loss of manpower and material resources
