Urban sewage irrigation station and self-irrigation drainage system

Abstract

The invention discloses an urban sewage irrigation station which comprises a sewage input pool, a sewage irrigation pool, an overflow well and a drainage pipe. The drainage pipe comprises a first vertical pipe body, a middle pipe body and a second vertical pipe body which are sequentially communicated and arranged in a sealed mode. The first vertical pipe body is vertically arranged in the sewage irrigation pool, and the water inlet end of the first vertical pipe body is located below the water level of the sewage irrigation pool. The second vertical pipe body is vertically arranged in the overflow well, and the water outlet end of the second vertical pipe body is located below the water level of the overflow well. An overflow opening for allowing sewage to be drained is further formed in the overflow well, and the position of the overflow opening is lower than a lower opening of a water inlet sewage pipe and higher than the water inlet end of the first vertical pipe body. Due to the fact that the overflow opening is lower than a water inlet pipe of a sewage inlet pool, a siphonic effect is formed, after the drainage pipe is filled with air after air is completely exhausted, sewage in the sewage irrigation pool can be naturally drained into the overflow well from the drainage pipe and drained out through the overflow opening formed in the overflow well, and natural drainage can be achieved without exogenic action.

Description

technical field [0001] The invention relates to the technical field of urban sewage drainage, in particular to an urban sewage lifting and irrigation station and a self-lifting irrigation and drainage system. Background technique [0002] The impact of sewage discharged from various types of production and living in cities on the social environment and the natural environment is an obvious and common problem. At present, the representative urban sewage discharge method is: except for a few more harmful sewage sources, most of the pollution sources formed by sewage are directly discharged into the main sewage pipeline network of the city, and then, after a large sewage treatment plant passes through After centralized treatment, it is discharged externally. [0003] When the existing urban sewage pipeline network is installed, there is a slope of five thousandths. When the urban sewage pipeline is installed to a certain depth, a sewage lifting and irrigation station needs to ...

AI Technical Summary

Problems solved by technology

In many large cities, there are multi-level irrigation stations from the starting point to the end point of the sewage treatment plant, and each level of irrigation station needs to be equipped with several pumps. This kind of irrigation station not only wastes electricity, but also increases government investment. Special personnel are needed for management and maintenance, which increases labor costs, and the noise of the lift-irrigation pump is relatively loud during operation, forming a certain amount of noise pollution, which affects the life and rest of nearby residents; especially for pump stations without dual power supplies, power outages or line maintenance. The pumping station uses a diesel generator set, which produces louder noise and smoky gas emissions, often causing complaints from surrounding residents
