Precipitation pool for sewage treatment

Abstract

The invention relates to the technical field of environmental protection equipment, particularly to a precipitation pool for sewage treatment. According to the invention, with the precipitation pool,precipitates and floaters in sewage are automatically cleaned so as to improve s sewage quality, save physical strength and time, improve working efficiency, reduce impurity residues, reduce the riskof falling of people into water and improve practicability and safety; and the precipitation pool comprises a box body, a collecting box, supporting legs, a water inlet pipe, a first water discharge pipe, two sets of mounting plates, two sets of guide rails, two sets of tooth rows, two sets of sliding blocks, four sets of connecting columns, two sets of connecting plates, two sets of gears and a first motor, wherein a first cavity is formed in the box body, the top end of the first cavity is communicated to a first through opening, and the left side of the bottom end of the first cavity is communicated to a collecting groove.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to a sedimentation tank for sewage treatment. Background technique [0002] As we all know, sewage is extremely harmful to the environment, and the sewage treatment process has been widely used in the field of environmental protection. Generally, there are many granular impurities in sewage, and the density of impurities is higher than that of water. The precipitation method is generally used to treat such impurities. Separation, the sedimentation method is mainly to keep the sewage still in the sedimentation tank, so that the impurities are naturally precipitated, so that the impurities are separated from the water, and the upper layer of water can be extracted. When the traditional sedimentation tank is used, a large amount of silt is generated at the bottom of the sedimentation tank. Manual cleaning is often performed to prevent excessive accumulation o...

[0002] As we all know, sewage is extremely harmful to the environment, and the sewage treatment process has been widely used in the field of environmental protection. Generally, there are many granular impurities in sewage, and the density of impurities is higher than that of water. The precipitation method is generally used to treat such impurities. Separation, the sedimentation method is mainly to keep the sewage still in the sedimentation tank, so that the impurities are naturally precipitated, so that the impurities are separated from the water, and the upper layer of water can be extracted. When the traditional sedimentation tank is used, a large amount of silt is generated at the bottom of the sedimentation tank. Manual cleaning is often performed to prevent excessive accumulation of silt. At the same time, the surface of the sewage is prone to produce more floating objects, which need to be salvaged manually. Manual operation requires a lot of physical strength, long working hours, and low work efficiency. Manual cleaning Incomplete, there are still many such impurities in the sewage, and at the same time, the safety of people is poor, and it is easy to fall into the water
