Owing to have employed technique scheme, this utility model compared with prior art, method of the present utility model for
The deficiency of existing denitrification reactor, it is proposed that improvement project, effectively solves four existing for existing denitrification reactor big
Shortcoming.Tests prove that, this utility model can greatly reduce the investment of technique, and can be effectively improved nitrogen in sewage go decapacitation
Power.Structure of the present utility model is integrated, the advantage effectively incorporating three class reactors, and is greatly saved occupation of land
Area.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Being labeled as in figure: 1-water inlet, 2-waste mouth, 3-swash plate inhalant region, 4-hydrolyze contact area, the distribution of 5-gas
Plate, 6-grid, 7-carrier, 8-aerobic aeration district, 9-aerator, 10-limited aeration valve, 11-de-bubble Fen Qi district, 12-baffling
Anaerobic denitrification district, 13-aeration pump, 14-outlet, the micro-aeration opening of 15-, 16-microwell plate, 17-row bubble mouth, 18-swash plate.
Detailed description of the invention
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings, but not as new to this practicality
Any restriction of type.
This utility model is that the improved method according to following a kind of denitrogenation biological filter is constituted, as it is shown in figure 1, should
Denitrogenation biological filter described in method uses micro-biological aerated filter mode, to improve the biodegradability of sewage and to reduce mud
Discharge capacity；Use deflection plate to realize efficiently separating of muddy water in anaerobic zone；The deflection plate of anaerobic zone uses long deflection plate to carry
The biological denitrificaion ability of high whole device, it is achieved the optimization of whole device and high efficiency；The water inlet of denitrogenation biological filter uses
Swash plate is intake and arranges waste mouth, with effective inorganic matter got rid of in water inlet and bulky grain thing, reduces in sewage with stabilizing water quality
The impact to reactor of the not biodegradable inorganic matter；In the middle of aerobic aeration district and deflector anaerobic denitrogenation district, arrange de-bubble divide
Gas district, effectively to reduce the dissolved oxygen in muddy water and to separate the bubble of floating so that enter the sewage energy in deflector anaerobic denitrogenation district
It is rapidly achieved the degree for the treatment of of anoxia and anaerobism.
According to the improved structure of of the present utility model a kind of denitrogenation biological filter that said method is constituted, as it is shown in figure 1, bag
