Split-flow purification device for urban domestic sewage and rainwater treatment

Abstract

The invention discloses a split-flow purification device for urban domestic sewage and rainwater treatment. The split-flow purification device comprises a device shell, a rainwater pipeline, a first rectangular sliding groove, a treatment barrel, an internal threaded pipe and an alloy screw rod, a first sealing cover plate is fixed to the outer side of the device shell through bolts, and a liquidstorage box body is welded and fixed to the upper portion of the device shell; and first sewer pipelines are arranged on the left side and the right side of the liquid storage box body, a drainage connecting pipe is fixedly welded to the bottom of the device shell, a second sewer pipeline is fixedly welded to the outer side of the drainage connecting pipe, a sealing rubber ring is fixedly bonded to the outer side of the rainwater pipeline, and a first equipment box body is arranged under the rainwater pipeline. The split-flow purification device for urban domestic sewage and rainwater treatment is provided with the internal threaded pipe and the rectangular sliding groove; and the treatment barrel is driven by the internal threaded pipe to vertically ascend and descend, the height of the treatment barrel is adjusted according to the depth of accumulated water and the height of a road surface, and the rainwater treatment and extraction efficiency in the treatment barrel is improved.

Description

technical field [0001] The invention relates to the technical field of domestic sewage treatment, in particular to a split purification device for urban domestic sewage and rainwater treatment. Background technique [0002] When the continuous precipitation exceeds the urban drainage capacity, resulting in waterlogging disasters in the city, the drainage pipe network in some domestic cities has a lot of debts, the pipes are aging, and the drainage standard is relatively low. The rainwater cannot be transported and discharged to the nearby sewage treatment plant in a short time. In some places, the drainage facilities are not perfect, and domestic sewage and rainwater are generally collected and discharged in a centralized manner. Large-scale waterlogging and pollution. [0003] The current urban sewage treatment usually adopts a split structure. In the process of collecting rainwater, it is generally necessary to collect the road surface water through the sewer on the roads...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to provide a diversion purification device for urban domestic sewage and rainwater treatment, to solve the above-mentioned background technology, the automation degree of the diversion purification device is low, and it is difficult to adjust the collection structure according to the length of the road and the depth of the accumulated water. Highly adjustable, a single treatment structure is difficult to effectively classify rainwater and domestic sewage, which in turn affects the effect of sewage diversion and treatment.
