Description

Technical Field

[0001] The utility model relates to a riverside domestic sewage collection system. Background Art

[0002] The new negative pressure sewage collection technology developed in recent years overcomes the difficulties of traditional gravity flow sewage collection due to the small diameter of the sewage collection pipe. It first collects the scattered sewage nearby and enters the negative pressure collector, and then uses the negative pressure to suck the sewage in the negative pressure collector into the pipeline at high speed and transport it to the liquid storage tank of the negative pressure power center station. However, it also has problems such as cumbersome maintenance of the negative pressure collector, difficulty in locating when a fault occurs, and the failure of some negative pressure collectors will lead to the reduction of the negative pressure extraction function of the total system. Therefore, the negative pressure sewage collection technology also has obvious defects in the collection of domestic sewage near the river in front of and behind houses; in addition, the traditional sewage collection pipelines along the river and the sewage siphons across the river are silted up all year round, but because the pipeline dredging vehicles cannot enter the site, the pipeline sedimentation and siltation cannot be cleared in time, affecting the service life of the sewage collection pipeline system along the river. The water bodies near the river in front of and behind houses are the focus of rural water environment governance, and it is urgent to develop new methods suitable for the collection of domestic sewage near the river in front of and behind houses in villages and towns.
