Municipal engineering drainage system

Abstract

The invention relates to the technical field of municipal drainage, in particular to a municipal engineering drainage system. The municipal engineering drainage system comprises a sewage collection pipeline, a rainwater collection pipeline and a sewage disposal pool; domestic sewage in each house is collected through the sewage collection pipeline and is intensively discharged into a sewage confluence pipeline; road rainwater drainage openings are formed in the two sides of an urban road, accumulated water on the road surface flows into the rainwater collecting pipeline through the road rainwater drainage openings, and road surface sundries are prevented from entering the pipeline through filtering baffles to cause pipeline blockage; the sewage confluence pipeline and the rainwater confluence pipeline are integrated into an integrated structure through the pipeline support, the construction range is narrowed, meanwhile, rainwater and sewage can be separated, and the energy-saving and environment-friendly effects are achieved; and after sewage in the sewage confluence pipeline is treated by the sewage disposal pool, purified discharge water is obtained, and the purified discharge water enters the rainwater confluence pipeline again and is discharged after detection reaches the standard, so that pipeline arrangement is saved, and meanwhile, the water source environment is not polluted.

Description

technical field [0001] The invention relates to the technical field of municipal drainage, in particular to a municipal engineering drainage system. Background technique [0002] In my country, municipal facilities refer to various buildings, structures, equipment, etc. that are set up within the planning and construction scope of urban areas, towns (townships), and provide residents with paid or unpaid public products and services based on government responsibilities and obligations. The construction of various public infrastructure supporting urban life belongs to the category of municipal engineering, such as common urban roads, bridges, subways, and various pipelines closely related to life: rainwater, sewage, water supply, reclaimed water, electricity (outside the red line) Partial), telecommunications, heat, gas, etc., as well as the construction of squares, urban greening, etc., all belong to the category of municipal engineering. [0003] Among them, the drainage sy...

Problems solved by technology

[0003] Among them, the drainage system is particularly important for urban and rural construction. The domestic sewage mainly comes from the waste water generated in people's daily life and eating and living, which is discharged through sewer pipes or sewage pipes; in urban rainwater drainage design, most of the domestic sewage is discharged to the users Draining rainwater into the rainwater drainage channel of the river. Although this method brings convenience in architectural design and construction, it does have certain defects in terms of environmental protection. The existing sewage mixes with rainwater and flows into the river. , and the untreated sewage has caused great damage to the river and the surrounding ecological environment; not only that, because domestic sewage is mixed with different impurities, many domestic sewage impurities have been deposited in the rainwater drainage channel without being washed by rainwater, accumulating over time , reducing the drainage area and water flow of the rainwater drainage channel
