Embodiment
Embodiment 1
As shown in Figure 1, Fig. 1 is a structural representation of the present utility model.
The utility model is a kind of deep water combination biochemical treatment facility, and it is in darker sewage lagoon body 1, with the anaerobic biochemical reactor A that disperses to be provided with, aerobic biochemical reactor O, settling tank S, BAF is combined together, and by diaphragm 6 it is split up into several segmentations respectively.Specifically be successively it to be divided into anaerobic biochemical reactor A by dividing plate 10 and dividing plate 11, aerobic biochemical reactor O, three segmentations of settling tank S; The one side of pond body 1 is provided with water inlet pipe 2, and another side is provided with water shoot 3, and body 1 bottom in pond is provided with one or more shore pipes 5; Anaerobic biochemical reactor A can be divided into multistage with traverse baffle 7,8,9; Aerobic biochemical reactor O adopt to promote aeration mode, in be provided with diaphragm 6, monolateral lifting aeration mode forms vertical water circulation, regulates to adapt to deep water, saves energy.Settling tank S can adopt upward flow settling tank structure, also can establish swash plate.The water level of described pond body 1 is to be advisable between the 6-12m, anaerobic biochemical reactor A wherein, and aerobic biochemical reactor O, three segmentation water levels of settling tank S are equal substantially.
During concrete enforcement, the utility model by reducing anaerobic biochemical reactor A section height, drops in the 12m its water level for adopting multistage anaerobic reactor; Improve aerobic biochemical reactor O section water level depth and anaerobic biochemical reactor A section coupling; Adopt upflowing settling tank S, make its water level and aerobic biochemical reactor O section coupling.Settling tank S can be the underlying upflowing, adapts to the big depth of water.By above measure, biochemical flow process is unified in the integrated rectangle reaction tank body 1 of a basic water level such as grade.
Sewage enters first segmentation anaerobic biochemical reactor A from water inlet pipe 2, and the traverse baffle 7,8,9 of flowing through successively that flows automatically enters among next segmentation aerobic biochemical reactor O, and aerobic biochemical reactor O section air-lift unit aeration is saved the energy; And provide aeration wind through aerated conduit 4, again through settling tank S, by upward flow sewage through suspended layer upwards through swash plate S1 secondary sedimentation, discharge pond bodies 1 via the water shoot 3 of settling tank S section at last, surplus mud is discharged by shore pipe 5.Pass through anaerobic biochemical reactor A, aerobic biochemical reactor O, settling tank S therebetween ...
