High concentration domestic sewage treating system

Abstract

The present invention relates to a high-concentration domestic sewage processing system which mainly comprises a primary filtering device, an oxygen-deficient biochemical treatment fluid bed, an anaerobic biochemical treatment fluid bed and an aerobic biochemical treatment fluid bed that are connected in series, the primary filtering device is composed of a plurality of filtering modules, the oxygen-deficient biochemical treatment fluid bed is arranged with a plurality of oxygen-deficient biochemical processing modules, the anaerobic biochemical treatment fluid bed is arranged with a plurality of anaerobic biochemical treating modules, and the aerobic biochemical treatment fluid bed is arranged with a plurality of aerobic biochemical treating modules. The system is suitable for executing the procession of the small-scale high-concentration domestic sewage and has the advantages of excellent processing effect, compact structure, flexible installation and small accommodation area. The system of the invention is suitable for the sewage processing of the resident living area.

Description

technical field [0001] The invention relates to a high-concentration domestic sewage treatment system, which belongs to the technical field of environmental protection. Background technique [0002] With the application of separate collection and discharge of domestic sewage sources, domestic sewage will be divided into two categories, one is general biochemical sewage, which is characterized by low pollution concentration, and can reach the reuse standard of reclaimed water after simple treatment. The second category is the high-concentration domestic sewage from toilets. The main source of pollutants is the toilet. The amount of discharge is small, and it is not suitable for centralized treatment, so it is necessary to develop suitable small-scale and efficient treatment facilities. Contents of the invention [0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a high-concentration domestic sewage treatment system, wh...

Problems solved by technology

[0002] With the application of separate collection and discharge of domestic sewage sources, domestic sewage will be divided into two categories, one is general biochemical sewage, which is characterized by low pollution concentration, and can reach the reuse standard of reclaimed water after simple treatment. The second category is high-concentration domestic sewage from toilets, whose main source of pollutants is toilets. The concentration of this kind of sewage is very high, and the existing domestic sewage treatment technology cannot meet the discharge or reuse standards at all, but due to its The emission is small, and it is not suitable for centralized treatment, so it is necessary to develop suitable small and efficient treatment facilities
