Combined-type advective biochemical sewage treatment device

Abstract

The invention relates to a combined-type advective biochemical sewage treatment device, which comprises a plurality of standardized advective reaction boxes that are in parallel to each other. The box body of the advective reaction box is rectangle, and two ends thereof are provided with three identical connection short pipes with identical flanges, namely, an upper connection short pipe, a middle connection short pipe and a lower connection short pipe; a plurality of advective baffles which are in parallel to each other are mounted in the box body of the advective reaction box; the advective baffles have two kinds; wherein, one kind is located in the central part of the box body, and a gap is arranged between the two sides of the baffle and the side walls of the box body to form a current passage, while the other kind is formed by two plates on the same plane, outside ends of the two plates are connected with the two side walls of the box body separately, and a gap is arranged between the two plates to form a current passage; the two baffles are alternately distributed; the baffle which is next to the inlet and the outlet uses the one which is mounted in the central part of the box body. The invention can be assembled with treatment devices of other box bodies in other specifications at will, thus reducing cost, simplifying installation, and ensuring treatment effect of sewage. The reaction tank in the invention can be used as an activated sludge tank, a baffled precipitation tank, a flocculation reaction tank after flocculation mixing and the like.

Description

technical field [0001] The invention relates to sewage treatment equipment, in particular to a combined advection sewage biochemical treatment device, which belongs to the technical field of environmental protection. Background technique [0002] For small-scale sewage discharges that often occur in life or production, especially in places far away from municipal pipes, it is necessary to set up a small sewage treatment system for sewage treatment to make it meet the discharge standards for on-site discharge. This type of small-scale sewage Due to the small processing capacity of the treatment system, the investment that can be borne is not large. Therefore, a finished product with wide adaptability and relatively low cost is required to produce a unified finished product in the factory without independent design for various specific sewage properties. and engineering construction. In view of the fact that such pollutants usually exist in sewage: floating substances such as...

AI Technical Summary

Problems solved by technology

[0003] However, due to the different amounts of sewage discharged from different sewage sources, a single sewage treatment system cannot be adapted to the sewage treatment of various sewage discharge sources, and the pre-production of various sewage treatment systems with different specifications not only requires more cost in design and production Large, and the treatment process for different sewage may also be different, so the adaptability of the pre-designed and produced treatment equipment will be problematic
