Abstract

The invention belongs to the technical field of sewage disposal technology and particularly relates to a concentrated and integrated sand and water separation device. The concentrated and integrated sand and water separation device aims at separating sand and water in sand and water mixed liquid discharged from a grit chamber of a sewage disposal plant, reinforcing removal of fine sand and reducing organic content on sand surfaces to further release a carbon resource. According to the technical scheme, the concentrated and integrated sand and water separation device comprises a sand concentrator and a sand and water separator; the sand and water separator comprises a collection hopper water tank and a spiral sand washing device; the sand concentrator is connected to the collection hopper water tank. The concentrated and integrated sand and water separation device is used for separating the sand and the water in the sewage disposal plant, reinforcing the removal of the sand, reducing the organic content on the sand surfaces and promoting organic entrapment.

Description

technical field

[0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a concentration and integrated sand-water separation device. Background technique

[0002] In the prior art, the sand-water separator used in conjunction with the cyclone grit chamber only has a certain dehydration ability for the sand-water mixture lifted up from the grit chamber, and can separate sand particles with a particle size greater than 0.2mm, while a large amount of The fine sand will flow back to the sewage treatment system along with the water outlet on the sand-water separator. According to research, the concentration of inorganic particles in the sewage plants in southern cities and mountainous cities in my country is high and the particle size is small. Affected by the poor sedimentation of inorganic particles in the grit chamber, the concentration of particles in the water-solid mixture lifted to the sand-water separator is low. , the separat...
