An urban underground pipeline wastewater treatment device

Abstract

The invention relates to the field of sewage treatment devices, in particular to a waste water treatment device for urban underground pipelines, comprising a connecting pipe, a well barrel, a driving structure, a sealing structure, an anti-blocking structure, a storage structure, a filtering structure and a drainage hole; the storage structure is designed In the inside of the well barrel, it is convenient to store the film waste filtered by the filter structure through the storage structure. The storage structure and the well barrel can be slidably connected, so that the storage structure can be lifted by lifting equipment when cleaning the film waste, so that the storage structure Sliding with the well barrel, the storage structure slides out of the well barrel, making the garbage cleaning inside the storage structure more convenient and quick; the driving structure is located inside the well barrel, and the driving structure is connected to the storage structure through the drainage hole, and the sewage enters the driving structure , the potential energy of the water flow is converted into the kinetic energy of the driving structure, so that the driving structure drives the sealing structure to prevent blocking, and the filtering structure is driven to salvage the plastic film in the sewage, so that the filtering performance is better, and the pressure on the connecting pipe is reduced at the same time.

Description

technical field [0001] The invention relates to the field of sewage treatment devices, in particular to a sewage treatment device for urban underground pipelines. Background technique [0002] With the rapid development of society and the improvement of municipal drainage system, it also has good flexibility in adapting to environmental changes and dealing with natural disasters caused by rainwater. The adaptation of filtering devices in pipelines can improve the functions of urban ecosystems and reduce urban floods. The occurrence of disasters can also reduce the impact of waste-carrying liquid or garbage in water discharged from residences, institutions, commercial or industrial areas mixed with groundwater, surface water, snowstorms, etc. on water bodies. [0003] However, most of the sewage filtering devices in existing municipal pipelines are grid-shaped filters, and the plastic film garbage in urban underground pipelines is easy to block the grid-shaped filter screen, ...

AI Technical Summary

Problems solved by technology

[0003] However, most of the sewage filtering devices in existing municipal pipelines are grid-shaped filters, and the plastic film garbage in urban underground pipelines is easy to block the grid-shaped filter screen, which makes the filter performance of the filter screen worse and affects the drainage capacity of the pipeline. It makes the flood resistance ability worse, which is not conducive to use in areas with heavy rain in the south, and the plastic film is bonded to the filter net, which is not easy to dredge and clean up. The filtered waste is in the sewage filter well, which needs to be salvaged by the staff. Garbage and debris on the road can easily block the manhole cover and affect the drainage capacity of the manhole cover
