Urban underground pipeline wastewater treatment device

Abstract

The invention relates to the field of sewage treatment devices, in particular to an urban underground pipeline wastewater treatment device, which comprises connecting pipes, a well barrel, a driving structure, a seal structure, an anti-blocking structure, a storage structure, a filtering structure and a drainage hole. The storage structure is arranged in the well barrel, and is convenient for storage of film scraps filtered by the filtering structure, the storage structure and the well barrel are slidably connected, so that the storage structure can be lifted by lifting equipment during cleaning of film scraps, and the storage structure and the well barrel can achieve sliding, the storage structure can slide out of the well barrel, and garbage cleaning in the storage structure can be moreconvenient and efficient. The driving structure is disposed in the well barrel, and is communicated with the storage structure through the drainage hole, sewage enters the driving structure and transforms the potential energy of water flow into the kinetic energy of the driving structure, so that the driving structure can drive the seal structure to prevent blocking and drive the filtering structure to fish plastic films out of the sewage, therefore, the filtering performance can be better, and meanwhile the pressure on the connecting pipes is reduced.

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, ...

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 wors
