Sewage treatment equipment

Abstract

The invention discloses sewage treatment equipment and belongs to the field of water treatment. The equipment comprises an anaerobic tank, an aerobic tank, a sedimentation tank, insertion hole, biochemical plug-in units and a hoisting structure; the plurality of plug-in holes are distributed at equal intervals and are transversely formed in the upper tank walls of the anaerobic tank and the aerobic tank; the plurality of biochemical plug-in units are inserted into the plug-in holes in a sliding manner and extend into the anaerobic tank or the aerobic tank; and the hoisting structure is arranged above the aerobic tank and the anaerobic tank. According to the sewage treatment equipment of the invention, treatment and precipitation of organic matters in sewage are realized through the anaerobic tank, the aerobic tank and the precipitation tank; and by means of the modularly plug-in biological plug-in units on the anaerobic tank and the aerobic tank, when microorganisms on biological carriers of the biological plug-in units die and need to be replaced, the biological plug-in units are hoisted through the hoisting structure, and then the microorganisms in the biological plug-in units can be supplemented conveniently, and the biological plug-in units can be maintained and replaced conveniently.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to sewage treatment equipment. Background technique [0002] In sewage (waste) water treatment, biochemical processes are more common; in order to improve the treatment effect of biochemical processes, microbial carriers will be added to biochemical pools. At present, the common ones are contact oxidation tank, MBBR (moving bed biofilm reactor) and so on. However, the microbial carrier of the contact oxidation tank process is evenly fixed on the bottom of the pool, but it is difficult to repair the microbial carrier after it is damaged. The microbial carrier (MBBR filler) of MBBR process is easy to gather at the water outlet with the water flow, and the microbial carrier (MBBR filler) is unevenly distributed in the pool, and it is easy to cause the outlet to be blocked. [0003] The patent application whose patent publication number is CN111268790A discloses a technical scheme, a fi...

Problems solved by technology

[0004] The above-mentioned technical solution solves the problems raised in the above-mentioned background technology to a certain extent, but it uses multiple cage structures as storage platforms for biological carriers, and fixes them on the body of the biochemical pool, but in actual use, the biological carrier After long-term use, the bacteria on it will die, which will lead to the failure of the biological carrier. At present, the entire biochemical pool is usually dismantled and rebuilt after the death of the bacteria, which greatly wastes the cost. Therefore, a A kind of sewage treatment equipment that solves the above problems
