Technical Field

[0001] The utility model belongs to the technical field of sedimentation tanks, and in particular relates to an improved sedimentation tank for industrial wastewater treatment. Background Art

[0002] Industrial wastewater includes production wastewater, production sewage and cooling water, which refers to wastewater and waste liquid generated in the industrial production process, which contains industrial production materials, intermediate products, by-products and pollutants generated in the production process that are lost with water. In the early stage of industrial wastewater treatment, in order to remove impurities in the water, the wastewater is often transported to a sedimentation tank for flocculation and sedimentation treatment;

[0003] After the sewage enters the sedimentation tank, a certain amount of flocculant needs to be sprinkled into the sedimentation tank. The flocculant then diffuses and contacts with impurities in the water to form flocculated sediments, thereby effectively removing impurities in the water. However, the natural diffusion time of the flocculant is relatively long, which will affect the processing efficiency of the sewage. In addition, the common sedimentation tanks currently require manual cleaning during use, and the cleaning of the flocculated sediments requires manual entry into the tank body, which is relatively cumbersome and inconvenient. Based on this, the utility model provides an improved sedimentation tank for industrial wastewater treatment. Utility Model Content
