Description

Technical Field

[0001] The utility model specifically relates to an improved rapid separation biochemical sewage treatment device, belonging to the technical field of sewage treatment. Background Art

[0002] The rapid biochemical sewage treatment combines the "displacement" principle in fluid mechanics with the O / A biofilm technology of microbial immobilization. It is a method that makes the suspended solid particles in the sewage gather outside the rapid biochemical ball, forms a complete biological chain along the water flow direction of the rapid biochemical pool, and repeatedly performs the "aerobic-anaerobic-aerobic" coupled biological treatment process. The rapid biochemical sewage treatment device is widely used in industrial sewage treatment, domestic sewage treatment, community water reuse treatment, landscape environment water body comprehensive management and other fields. When the existing rapid biochemical sewage treatment device is in use, the solid impurities in the sewage are easily attached to the inner wall of the treatment pool, affecting the overall treatment effect of the sewage. At the same time, after long-term use of the rapid biochemical ball, it is easy to cause blockage, and it is inconvenient to clean and replace it. When it is necessary to add flocculants to the sewage to combine with dissolved impurities, the flocculants are not fully combined with the dissolved impurities in the sewage, affecting the sewage treatment effect. When adding a stirring structure to make the flocculants mix evenly in the sewage, it is not energy-saving enough, increasing the sewage treatment cost, and there are certain disadvantages in the use process.

[0003] In view of this, the present utility model is proposed. Utility Model Content
