Preferred: described sour import, alkali import, nitrogenous source import, the import of phosphorus source are all higher than the height of water inlet.
Preferred: described microbe stuffing is spherical hollow polymer.
Preferred: described PH on-line detector comprises pH value display, this pH value display leads to the outside of described filtering ponds by connecting line.
The beneficial effects of the utility model are: this biofilter, compared with the structure of existing filter, adds a set of microbe stuffing streaming architecture, namely by pressure water pump, the import of fluidisation liquid, fluidisation liquid distributor.After biofilter runs a period of time, when treatment effeciency reduces, can opening pressure water pump, liquid bottom filtering ponds sprays in microbe stuffing fast through pressure water pump supercharging, make microbe stuffing fluidisation and redistribute, nutriment, moisture is made to be assigned in microbe stuffing equably, subregion biomembrane in filler can be removed and accumulate excessive problem, in final promotion filler microbial film homoepitaxial, upgrade fast, improve the treatment effeciency of organic exhaust gas substantially.
Accompanying drawing explanation
Fig. 1, structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing and preferred scheme, detailed description of the invention of the present utility model is described in further detail.
As shown in Figure 1, for structural representation of the present utility model, specifically a kind of biofilter processing organic exhaust gas, this biofilter comprises: the bulk filter pond 20 of filter, filter the fluidisation liquid import 1 of offering on 20, clean gas outlet 6, exhaust gas inlet 7, water inlet 8, liquid-circulating outlet 9, acid import 10, alkali import 11, nitrogenous source import 12, phosphorus source import 13, the fluidisation liquid distributor 2 that filtering ponds 20 inside is arranged, waste gas distributor 3, microbe stuffing 4, liquid distribution trough 5, PH electrode 14, PH on-line detector 15, the circulating pump 16 of filtering ponds 20 external peripheral and pressure water pump 17.Described clean gas outlet 6 is located at the top of filtering ponds 20 outside; The bottom of filtering ponds 20 outside is located in described liquid-circulating outlet 9; Described fluidisation liquid distributor 2 is located at the bottom of microbe stuffing 4, and fluidisation liquid distributor 2 is connected with fluidisation liquid import 1; The below of fluidisation liquid distributor 2 is located at by described waste gas distributor 3, and waste gas distributor 3 is connected with exhaust gas inlet 7; Described liquid distribution trough 5 is arranged at the top of filtering ponds 20 inside, and liquid distribution trough 5 is by the external circulating pump 16 of pipeline, and the other end of circulating pump 16 and liquid-circulating export 9; Import and the liquid-circulating of described pressure water pump 17 export 9, and its outlet is connected with fluidisation liquid import 1; Described PH electrode 14 and PH on-line detector 15 are arranged at the bottom of filtering ponds 20, and PH on-line detector 15 is connected with PH electrode 14.
Embodiment: the present embodiment illustrates in conjunction with preferred version, the sour import 10 in the present embodiment, alkali import 11, nitrogenous source import 12, phosphorus source import 13 are all higher than the height of water inlet 8; Described pH on-line detector 15 comprises a pH value display 18, and this pH value display 18 leads to the outside of described filtering ponds 20, to observe registration by connecting line.
Filter process: first organic exhaust gas enters into filtering ponds 20 by exhaust gas inlet 7 through waste gas distributor 3, the superficial growth of the microbe stuffing 4 of spherical hollow polymer simultaneously has a large amount of degrading microorganisms; Then according to organic contamination substrate concentration in waste gas, add nitrogen, phosphorus nutrition material by nitrogenous source import 12 and phosphorus source import 13, add than the ratio for C:N:P=100:10:1 according to nutriment; Then in filtering ponds 20, liquid is injected by water inlet 8, the liquid generally injected from water inlet 8 is water, the acid-base value of liquid is monitored again by pH on-line detector 15 and PH electrode 14, here liquid refers to the mixing material of water and the nutriment entered by water inlet 8, if on pH value display 18 display numerical value not in the scope of 6.5-7.5, by sour import 10, alkali import 11 adds acid or alkali control ph is 6.5-7.5; Then open circulating pump 16, the liquid-circulating of filtering ponds 20 bottom is evacuated to the top of filter 20, be evenly sprayed on microbe stuffing 4 by liquid distribution trough 2; Organic exhaust gas is up to be contacted with the degrading microorganism of apposition growth on microbe stuffing 4, and is absorbed by biomembrane, and be finally degraded to water and carbon dioxide, the gas processed is got rid of from the clean gas outlet 6 on filtering ponds 20 top.After biofilter runs a period of time, when treatment effeciency is reduced to original about 80%, opening pressure water pump 17, liquid bottom filtering ponds 20, through pressure water pump 17 supercharging, enters fluidisation liquid distributor 2 by fluidisation liquid import 1, and is sprayed in microbe stuffing 4 rapidly, redistribute after making microbe stuffing 4 fluidisation, in final promotion filler microbial film homoepitaxial, upgrade fast, maximize its treatment effeciency, to reach the object of qualified discharge.
