Problems solved by technology

Sewage contains a lot of impurities (such as suspended particles and sediment), if these sewage directly flows into the sewage treatment equipment, it will cause damage
[0003] Generally, sewage needs to be pretreated before microbial purification treatment. The main purpose of sewage pretreatment is to remove impurities and sediment. Sewage treatment plants generally use pretreatment tanks to pretreat sewage. Remove the floating matter, and then naturally settle the sewage to make the sediment sink to the bottom of the pool, then discharge the water from the upper part of the pool, and finally clean up the sediment at the bottom of the pool. The whole process has many procedures and takes a long time. Pretreatment less efficient

Abstract

The invention provides a sewage pretreatment tank, and belongs to the technical field of sewage treatment equipment. The sewage pretreatment tank comprises a water tank body, a water outlet pipe, two fixing blocks, a connecting plate and a cleaning mechanism, a sewage cavity is formed in the water tank body, the water outlet pipe is fixedly connected with the top of the left side wall of the water tank body, the two fixing blocks are fixedly arranged on the two sides of the water tank body in the length direction, the connecting plate is horizontally arranged on the two fixing blocks located above the water tank body through a driving structure, the length direction of the connecting plate is consistent with the width direction of the water tank body, the driving structure can drive the connecting plate to move back and forth in the length direction of the water tank body, and when the connecting plate moves rightwards, the cleaning mechanism can be used for simultaneously removing impurities floating on the water surface of the sewage cavity and sludge deposited to the bottom of the sewage cavity. The sewage pretreatment tank can quickly remove impurities floating on the water surface and sludge precipitated to the bottom in sewage, and is simple and efficient.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment equipment and relates to a sewage pretreatment pool. Background technique [0002] As the country continues to promote green environmental protection, sewage is an important part of environmental pollution, and sewage treatment is also receiving more and more attention. Sewage contains a lot of impurities (such as suspended particles and silt), and if the sewage flows directly into the sewage treatment equipment, it will cause damage to it. [0003] Generally, sewage needs to be pretreated before microbial purification treatment. The main purpose of sewage pretreatment is to remove impurities and sediment. Sewage treatment plants generally use pretreatment tanks to pretreat sewage. Remove the floating matter, and then naturally settle the sewage to make the sediment sink to the bottom of the pool, then discharge the water from the upper part of the pool, and finally clean up the sediment...
