Sewage treatment system combined by standard box bodies

Abstract

The invention relates to a sewage treatment system combined by standard box bodies, which is formed by the connection of a plurality of treating boxes with different treating processes while the treating boxes with different treating processes use the box bodies in standard structure and size; wherein, two ends of the box body are separately provided with standard connection short pipes with standard flanges, which are often an upper connection short pipe, a middle connection short pipe and a lower connection short pipe with flanges; the box bodies are connected with each other by connection hoses; the connection end of the connection hose is provided with a standard flange which has the same specification with the flange mounted on the box body; the flange mounted on the connection hose is connected with the flange mounted on the box body by a bolt; the cross section of the standard box body is rectangle; fiberglass reinforced plastic material or anti-corrosive paint is used for preservation in the box body; each box body is applicable to various sewage treatment processes such as aerobic biochemical treatment, anaerobic biochemical treatment, precipitation, filtration, floatation and the like. The box body in the invention is suitable for mass production in factories and is favor for reducing manufacturing cost while the site layout and installation are convenient.

Description

technical field [0001] The invention relates to a sewage treatment system combined with standard boxes, which belongs to the technical field of environmental protection and is suitable for medium and small sewage treatment systems with different displacements. 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 ...

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
