Embodiment Construction

[0031] Such as Figure 1 to Figure 3 As shown, a buried integrated domestic sewage treatment device includes grid pool 1, regulating pool 2, anaerobic digester 3, anaerobic biofilter 4, aerobic biofilter I5, and aerobic biofilter II 6. Aerobic biological filter III 7, vertical flow sedimentation tank 8 and control room 9. The control room 9 includes an upper part and a lower part. The upper part is equipped with an electric control box 10 and an ultraviolet device 20. The lower part Blower fan 23 and medicine box 24 are installed, can go up and down two floors by climbing ladder 12. The vertical flow sedimentation tank 8 is provided with a slant plate 11, and the vertical flow sedimentation tank 8 is equipped with a slant plate 11, which is beneficial to increase the sedimentation rate and improve the quality of the effluent.

[0032] The domestic sewage enters the grid tank 1 through the water inlet pipe 13 and then enters the adjustment tank 2 after being filtered. The bott...

Abstract

The invention discloses an underground integrated domestic sewage treatment device and a method thereof, and belongs to the field of purification of the domestic sewage. The underground integrated domestic sewage treatment device comprises a grilling tank, an adjusting tank, an anaerobic digestion tank, an anaerobic biological filtration tank, an aerobiotic biological filtration tank I, an aerobiotic biological filtration tank II, an aerobiotic biological filtration tank III, a vertical flow sedimentation tank and a control chamber, wherein the underground integrated domestic sewage treatment device is an underground stereoscopic integrated device; the control chamber comprises an upper layer part and a lower layer part; the upper layer part is arranged at the upper part of the control chamber; an electric control box and an ultraviolet device are arranged in the upper layer part; a fan and a chemical adding device are mounted at the lower layer part. The underground integrated domestic sewage treatment device is small in occupied area, convenient in drainage and low in energy consumption; the energy conservation and environment protection are facilitated; by virtue of the auxiliary adoption of the chemical treatment process on the main basis of biological degradation, the emission of the water with the up-to-standard water quality is ensured.

Description

technical field [0001] The invention relates to the field of domestic sewage purification, and specifically designs an underground integrated domestic sewage treatment device and method. Background technique [0002] At present, my country's sewage treatment is mainly for cities. In rural areas, due to scattered areas, large quantities, and difficulty in centralized collection and treatment of sewage, rural sewage in my country has always been neglected, and sewage is directly discharged without treatment. With the development of social economy and the scale of livestock breeding in rural areas, the pollution of rural domestic sewage to the environment is increasing year by year, and the problem of rural domestic sewage needs to be solved urgently. Contents of the invention [0003] The present invention aims at the above-mentioned problems of scattered rural domestic sewage, large quantity and difficulty in centralized treatment, and researches and designs an underground ...
