Bio-contact oxidizing treatment device using standard box

Abstract

The invention relates to a biological contact oxidation treatment device which adopts a standardizing box body, comprising the standardizing box body which takes a shape of a rectangle; both ends of the box body are respectively provided with three identical junction pipes which are arranged at the upper, middle and lower parts and are provided with flanges, the interior of the box body is fixedly provided with a packed bed which is located between the upper and the lower junction pipes, and the bottom of the box body is provided with an aerator. Cuboid or cylindrical plastic frame type filler or honeycomb filler, or the cuboid or cylindrical plastic frame type filler with soft packing is adopted as filler, thus expanding effective specific surface and enhancing sludge concentration and biochemical effect. The box body is made of corrosion resistant steel or is provided with an erosion resistant coating, and the erosion resistant coating can be made of glass fiber reinforced plastic material or anti-corrosive paint. The biological contact oxidation treatment device of the invention can be assembled with other treatment equipment with the same specification at will to build different treatment systems, thus reducing cost, simplifying installation and guaranteeing wastewater treatment effect.

Description

technical field [0001] The invention relates to sewage treatment equipment, in particular to a biological contact oxidation treatment device using a standard box body, 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 s...

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
