Sewage treatment device

Abstract

The invention discloses a sewage treatment device. The sewage treatment device comprises a sewage lifting pump, a debris filter mesh, a precipitation treatment tank and a sewage purification tank, wherein the sewage lifting pump is arranged in a tower type sewage tank, the debris filter mesh is movably arranged in the sewage tank in a circulating manner through a conveyor belt device, the precipitation treatment tank is connected with a water outlet of the sewage lifting pump, and the sewage purification tank is connected with the precipitation treatment tank. By arranging a crushing device, impurities in sewage can be fully crushed and refined, so that damages to the lifting pump device are reduced; by designing a turnover type filter hopper, the crushed impurities in the sewage can be well cleared and filtered; and by arranging a vibration device, the impurities adhered on the filter hopper can be vibrated to drop, so that the filtration working efficiency of the filter hopper is improved.

Description

technical field [0001] The invention relates to a sewage treatment device, in particular to a sewage treatment device used in the rear section of sewage lifting pump equipment. technical background [0002] At present, with the rapid development of industry and life, the types and quantities of wastewater have increased rapidly, and the pollution of water bodies has become increasingly widespread and serious, seriously threatening human health and safety. [0003] At present, although there are many measures in the treatment of wastewater, especially the preliminary filtration of sewage in the early stage is a key step that affects the entire treatment and subsequent treatment. , the fewer steps are used, the lower the cost of manpower and material resources, the higher the use value of the entire sewage equipment, and the higher the efficiency of general use. [0004] According to the classification of sewage sources, sewage treatment is generally divided into production s...

Problems solved by technology

[0006] Sewage treatment plants: Someone surveyed more than 100 large treatment plants, half of them are in the sun, and there are still insufficient funds, high costs, and low efficiency. The general efficiency is less than 70%, and the low one is only 40%

When the sewage lift pump is lifting the sewage, if the various impurities contained in the sewage are not treated, it will cause great damage to the equipment during the treatment process.
