A river sewage treatment process

Abstract

The invention discloses a river channel sewage treatment technology. The technology utilizes sewage treatment equipment; the sewage treatment equipment comprises a reaction tank, a flange, a water feeding hopper, a bottom support, a base, a discharging pipe, a motor, a retractable device, a bracket, a belt wheel, a transmission rod, a spiral unit, a filtering screen, a controller, a clamping block, a protection box and the like. The river channel sewage treatment technology disclosed by the invention has the beneficial effects that freshwater in sludge can be effectively extracted through a squeezing manner, so that people can utilize water resources to the greatest extent; meanwhile, the river channel sewage treatment technology can be used for sufficiently and effectively removing aquatic organisms, which possibly exist in some sewage pumped from the nature, and a condition that the aquatic organisms die in a sewage treatment process so that sewage is polluted again is avoided.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a river sewage treatment process. Background technique [0002] Sewage usually refers to some polluted discharge water from domestic and production, mainly domestic sewage, industrial sewage and initial rainwater. The main pollutants of sewage include pathogen pollutants, oxygen-consuming pollutants, plant nutrients and toxic pollutants, etc. . Sewage is accompanied by sludge, which also contains a large amount of fresh water, which is discharged along with the discharge of sludge, causing great waste, and the existing devices cannot effectively extract the fresh water in the sludge out, so that the protection and utilization of water resources have not been carried out to the extreme; at the same time, for the river sewage in some cities or villages, there may be aquatic organisms in the sewage, if these aquatic organisms are not effectively removed, the These aquatic organisms...

AI Technical Summary

Problems solved by technology

Sewage is accompanied by sludge, which also contains a large amount of fresh water, which is discharged along with the sludge, causing great waste, and the existing devices cannot effectively extract the fresh water in the sludge out, so that people's protection and utilization of water resources have not been carried out to the extreme; at the same time, for river sewage in some cities or villages, there may be aquatic organisms in the sewage, if these aquatic organisms are not effectively removed, the These aquatic organisms are treated together with the sewage treatment equipment, which may cause the death of these aquatic organisms during the sewage treatment process, resulting in re-pollution of the sewage
