[embodiment]
The defect existing for prior art, is described in further detail of the present invention for the ease of it will be appreciated by those skilled in the art that below in conjunction with accompanying drawing:
As shown in Figure 1, the novel ammonia nitrogen biological processor that the present embodiment discloses has very high removal effect for suspended substance, ammonia nitrogen, reduction CODcr that trade effluent, sanitary sewage are produced, be provided with the two-layer filtering layer with difference in functionality of packing layer and aerobic layer, in the time of former water process packing layer, can remove suspended substance, thereby turbidity is reduced, when removals such as nitrated, the lower ammonia nitrogen of denitrification by absorption, ion-exchange, microorganism, reduction CODcr after aerobic layer.And, after microbiological degradation, carrying out metabolism, recycling backwashing water carries out back flushing, and microorganism is regenerated.
In order to realize above-mentioned functions, the novel ammonia nitrogen biological processor that this programme discloses comprises raw water box 1, strumbox 2 and clear water tanks 3, between three casings, pass through pipeline connection, raw water box 1 is communicated with strumbox 3 tops by pipeline, in strumbox 3, be disposed with from top to down packing layer 21 and aerobic layer 22, the filler of this packing layer 21 is for the benefit of removed the natural zeolite that the particle diameter of particle in water and suspended substance is 4～6mm, and this bed stuffing height is 0.5～1.5m; Clinoptilolite that the particle diameter that described aerobic layer 22 is nitrated for having, denitrification is removed ammonia nitrogen microorganism is 3～5mm (aluminium silicate mineral of moisture sodium, potassium, calcium in zeolite family), this aerobic layer 22 is highly 2.5～3.5m, and be furnished with for removing ammonia nitrogen, reducing gas distribution pipeline 4 and the gas blower 5 of CODcr, gas blower 5 is blown into air by aerobic layer 22 belows to aerobic layer 22 by gas distribution pipeline 4, reaches the object of microorganism in regeneration aerobic layer 22.
The gas distribution pipeline 4 that this programme adopts is provided with multiple air outlets 41, and each air outlet 41 is uniformly distributed in aerobic layer 22 belows, and air outlet 22 arranges for being tilted to down 45 degree.41 apertures, air outlet of this gas-distribution pipe 4 are 2～3mm, between air outlet 41, are 200～300mm along pipe range direction spacing.In detail as shown in Figure 2.Occur corrosion for fear of gas-distribution pipe 4 after long-time use, gas-distribution pipe 4 tubing are manufactured with plastics.And the quantity of gas-distribution pipe 4 and large I are determined according to whole treater gas consumption, can be two parallel or many parallel installations.
