Embodiment Construction

[0032] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0033] figure 1 , figure 2 , image 3 A first embodiment of the invention is shown.

[0034] see figure 1 , figure 2 , image 3 As shown, the sewage treatment facility includes a housing 10 and an aerator 11 arranged on the inner wall of the bottom of the housing 10, and also includes a first deflector 12, a sludge bucket 13, a water distribution channel 14, and a second deflector 15 , settling area 16, overflow tank 17 and clean water tank 18; two first deflectors 12 perpendicular to the bottom surface of the housing 10 are arranged in the middle of the housing 10, and the inner cavity of the housing 10 is divided into the first aerobic reaction zone in turn 19. The anoxic reaction zone 20 and the second aerobic reaction zone 21, and the upper and lower ends of the first deflector 12 are spaced apart from the housing 10; the first aerobic reaction zone 19 and...

Abstract

The invention relates to a sewage treatment device and a sewage treatment method. The device comprises a housing, aerators arranged at the bottom of the housing, first deflectors, sludge hoppers, a water distribution channel, second deflectors, precipitate inclined plates, overflow tanks and clear water tanks. The two first deflectors perpendicular to the bottom of the housing sequentially divide the inner cavity of the housing into a first aerobic reaction zone, an anoxic reaction zone and a second aerobic reaction zone. When the device is working, sewage flows from a water outlet from the wall surface of the water distribution channel to the anoxic reaction zone, and then flows to the first and second aerobic reaction zones through the gaps between the first deflectors and the bottom of the housing; the sewage is aerated by the aerators; one part of the sewage is refluxed to the anoxic reaction zone from the upper parts of the first deflectors, and the other part flows into the sludge hoppers through deflector holes; after reaction precipitation, sewage is discharged from through holes at the tips of the sludge hoppers, and is circulated again; clear water flows through the precipitate inclined plates and is gradually overflown; the clear water is discharged to the clear water tanks through the overflow tanks, and is discharged to the outside. The device provided by the invention has the advantages of simple structure, convenient operation, regular flow pattern, high sludge concentration, high oxygen dissolution efficiency, low energy consumption, low construction cost, and low operation cost.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment equipment, in particular to a sewage treatment facility and a sewage treatment method thereof. Background technique [0002] At present, activated sludge is mainly used in the treatment of sewage and wastewater. The complex microorganisms in the activated sludge and the organic nutrients in the wastewater form a complex food chain, which has the advantages of complete degradation, easy operation, and low cost. [0003] The currently used bioreactor has a very high feeding rate. When treating sewage and wastewater, the sludge concentration can reach more than 6000mg / L, which is twice that of the general bioreactor. An existing combined alternating flow integrated bioreactor includes an activated sludge aeration tank, a biological contact oxidation tank and a biological aerated filter, and is composed of an activated sludge aeration tank, a biological contact oxidation tank and a biological...
