Description

Technical Field

[0001] The utility model relates to a sedimentation tank for sewage treatment, in particular to a sedimentation tank for sewage treatment with a material injection mechanism. Background Art

[0002] Sedimentation tank is a kind of equipment used to treat wastewater, which is used to remove impurities such as suspended particles, silt, biological pollutants, etc. in sewage. Sedimentation tank is an important part of the wastewater treatment system, which can precipitate pollutants in wastewater into sludge. This can effectively purify wastewater and protect the environment. Sedimentation tank mud often needs to be treated by adding flocculants. Flocculant is a chemical treatment agent in sedimentation tank. With the help of flocculant, fine particles in wastewater can be aggregated into large particles. In this way, the large particles aggregated are easily precipitated to the bottom of the sedimentation tank by gravity, thereby achieving the purification of wastewater. Due to the complex internal environment of the sedimentation tank and the presence of many pollutants, fine particles can easily block the pores in the sedimentation tank and interfere with the normal operation of the sedimentation tank. After adding flocculants, the aggregation speed and aggregation rate of particles can be effectively increased, making it easier for impurities in wastewater to be precipitated. Therefore, flocculants must be added to the sedimentation tank to better remove pollutants in wastewater.

[0003] When sedimentation is carried out in a sedimentation tank for sewage treatment, flocculants are generally added to assist the sedimentation. Multiple motors are installed above the sedimentation tank to drive the stirring shaft to rotate and stir and mix the flocculant and sewage. The stirring rod of the stirring shaft can mostly only stir in a single horizontal direction, and the stirring effect is not good. Utility Model Content
