Integrated rural domestic sewage treatment equipment and sewage treatment method

Abstract

The invention relates to integrated rural domestic sewage treatment equipment and a sewage treatment method, the integrated rural domestic sewage treatment equipment comprises a domestic sewage treatment integrated tank body, and the domestic sewage treatment integrated tank body comprises in turn an anoxic tank a first aerobic tank, a second aerobic tank, a chemical phosphorus removal sedimentation tank, a sand filtration tank and an equipment room; 1), the chemical phosphorus removal sedimentation tank is arranged between the equipment room and the sand filtration tank; 2) a compound fillercomprising 30%-40% of polyurethane and 60%-70% of a carbon fiber filler is arranged in the anoxic tank; 3) the first aerobic tank and the second aerobic tank are respectively provided with a compoundfiller comprising 60-64% of porous gel and 36-40% of a carbon fiber filler according to the filling rats of greater than 28% and less than 35%; and 4) the chemical phosphorus removal sedimentation tank comprises a flocculation reaction area and an inclined pipe sedimentation area, aerobic tank effluent is fully mixed with an iron salt phosphorus removal agent in a reaction zone, and is precipitated through the inclined pipe sedimentation area, supernate is discharged from an upper part overflow weir, and sludge is precipitated at the bottom of the sludge sedimentation tank, and is regularly pumped into a sludge tank.

Description

technical field [0001] The present invention relates to a microbial carrier that can provide good "moving bed" and "fixed bed" for microbial strains. It not only makes full use of microorganisms to purify water quality, but also avoids sludge contamination of clean water while cleaning sludge. The utility model relates to an integrated rural domestic sewage treatment equipment and a sewage treatment method which can effectively improve the aeration efficiency of the aeration tube while stirring the mud twice, and belongs to the field of sewage treatment equipment manufacturing. Background technique [0002] CN106007216A, titled "a horizontal integrated device suitable for rural domestic sewage treatment", including anaerobic and anoxic areas, aerobic areas, sludge reduction areas, sedimentation areas, equipment areas and solar photovoltaic panels, the anaerobic anoxic Fillers are placed in both the aerobic zone and the aerobic zone; the anaerobic anoxic zone, the aerobic zon...

AI Technical Summary

Problems solved by technology

[0004] The deficiencies of the above-mentioned background technology: the one is that because there is no good "moving bed" and "fixed bed" microbial carrier for microbial strains, the effect of biological water purification is not good; the other is that the sludge sedimentation treatment directly uses pump Not only can it not be cleaned, but also the treated water will be turbid and discharged directly during cleaning, polluting the environment; third, because the aeration pipe is designed to blow directly upward or downward, the aeration volume Small size, poor fluidity of water body, poor effect, did not achieve full utilization of air volume
