Apparatus for and method for filtering, treating and recycling seprobia

Abstract

The invention relates to a sewage biofiltration treatment, reusing equipment and a method thereof, comprising a biochemical treatment unit and a depth filtering treatment unit. The biological treatment area in the biochemical treatment unit is located on the internal layer or the external layer of the equipment, and is filled with filling materials. The filtering area is located on the internal layer or the external layer of the equipment. The top surface of the biological treatment area is provided with a water intake and distribution area which is connected with a sewage intake pipe and the undersurface is provided with a distribution system. The interior of the biological area is divided into at least one treatment area which comprises an aerobic zone through an aeration system and an entire biochemical treatment unit is formed. The upper part of the intake and distribution areas is provided with a clear water area. A sand washer which is connected with the water intake area is arranged in the clear water area. The sewage biofiltration treatment has the advantages of integrity and flexibility, low investment, operation expenditure and cost, high automation level and so on. The processing effect can reach the reused water quality standard of the relevant sewage treatment. The reused water can be used for road sprinkling, greening and irrigating, car washing, floor cleaning, industrial utilization and so on.

Description

technical field [0001] The invention relates to a sewage environmental protection treatment equipment and method, in particular to a sewage biological filtration and recycling equipment and method. Background technique [0002] Sewage treatment and reuse technology is actually basically divided into two parts, one is sewage treatment technology and method, sewage treatment can be divided into physical treatment technology, physical and chemical treatment technology, biochemical treatment technology and chemical treatment technology, among them The biochemical treatment technology of sewage is the most commonly used, and there are many kinds of biochemical treatment technologies, which are mainly classified according to the different conditions of microbial growth conditions and oxygen supply methods; the second is sewage reuse treatment technology, which can also be called advanced treatment technology. Coagulation dosing and filtration technologies are mostly used, and typi...

AI Technical Summary

Problems solved by technology

At present, the main treatment processes include biological contact oxidation method, biological aerated filter, etc., but they need to combine multiple pool structures or equipment, occupy a large area, and have high operating costs.
