A sewage recycling treatment device

Abstract

The invention discloses a circulating sewage treatment device. The circulating sewage treatment device comprises a filter tank, a squeezing dewatering device, a water inlet pipe and a water outlet pipe, wherein a first water inlet is formed in the upper end of the filter tank; a first water outlet is formed in the lower end of the filter tank; the water outlet pipe communicates with the first water outlet; a filter plate is arranged at the middle part of the filter tank; a first rotating screw is arranged in a sewage chamber; a sewage outlet is formed in the lower side of the sewage chamber; the squeezing dewatering device comprises a machine frame, a first motor, a sewage inlet, a sludge outlet, a second rotating screw and a movable-ring and fixed-ring filtering mechanism; the sewage outlet communicates with the sewage inlet; a water receiving tank is arranged below the movable-ring and fixed-ring filtering mechanism; the lower end of the water receiving tank communicates with the filter tank. The first rotating screw can improve the fluidity and the pressure intensity of water in the sewage chamber, so that the filtration efficiency is improved; the squeezing dewatering device opens a gate in time to discharge the accumulated high-concentration sewage, so that the filtration efficiency is prevented from decreasing, and the squeezed water is filtered again.

Description

technical field [0001] The invention relates to the technical field of sewage treatment equipment, in particular to a sewage circulation treatment device. Background technique [0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements of a certain water body for drainage or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and it has also increasingly entered the daily life of ordinary people, and there will be many problems in life. Sewage, so sewage treatment equipment is also used in life. At present, the existing domestic sewage treatment equipment on the market has a poor filtering effect when it is used. Basically, it is discharged after a simple filtration. This kind of filtration basically does not meet the discharge standard. It also affects the quality of the environ...

Problems solved by technology

At present, the existing domestic sewage treatment equipment on the market has a poor filtering effect when it is used. Basically, it is discharged after a simple filtration. This kind of filtration basically does not meet the discharge standard. also affect the quality of the environment

During the sewage treatment process, a large amount of sewage will gradually accumulate in front of the filter membrane of the filter tank. If it is not cleaned up in time, the filtering effect will be affected.
