Description
Technical field
The utility model relates to a kind of sewage disposal device, specifically relates to a kind of device of preposition anoxic biological aerated filter.
Technical background
Abroad study since 20 beginnings of the century, in basic forming at the end of the eighties, after update, and develop various ways.On stream, fully used for reference the mentality of designing of sewage disposal contact oxidation method and feedwater rapid filter, its maximum characteristics are to integrate bio-oxidation and hold back the suspended solids function, have saved follow-up second pond.But its ability of removing ammonia nitrogen mainly relies on biofilm surface and inner oxygen-starved area and the aerobic zone that forms, this removal ammonia nitrogen limited in one's ability, and can not be shock-resistant, use range is confined to handle the sanitary sewage of low-concentration organic and ammonia nitrogen, for being restricted in high concentrated organic wastewater and the high-concentration ammonia nitrogenous wastewater use, especially in circulating water system, seem particularly outstanding at industrial effluent reusing, the trade effluent variation water quality is big, the water-quality constituents complexity, the ammonia nitrogen concentration height, and ammonia nitrogen is had relatively high expectations in the recirculated water.The present invention adopts preposition anoxic denitrogenation, is intended to remove the organic while, improves the removal ability of ammonia nitrogen.Be a kind of improved form of biological aerated filter, its range of application is enlarged.
Summary of the invention
The utility model technology is primarily aimed at and improves the ammonia nitrogen removal effect, overcome the defective of traditional anoxic-aerobic process and biological aerated filter process, anoxic-aerobic process and biological aerated filter process are organically combined, have complementary advantages, oxygen-starved area and aerobic zone are designed to " returning " type or concentric-ring pattern structure, floor space is little, and is simple in structure.
In this technology, nitrification and denitrification is reflected in the same structures and carries out simultaneously, compares with traditional technology to have obvious superiority: (1) saves reactor volume and structures floor space, reduces investment; (2) can avoid NO to a certain extent
2 -Be oxidized to NO
3 -Restore into NO
2 -This unnecessary reaction of two steps, thus can shorten the reaction times, also can save DO and organic carbon; (3) basicity of anti-nitration reaction generation can remedy the consumption of nitration reaction basicity, reduces working cost.(4) save power consumption, cancelled the mud backflow, the power that the backflow of interior nitrification liquid utilizes the air blast air to provide has been cancelled interior nitrification liquid reflux pump.According to the situation of water outlet ammonia nitrogen, can utilize the flashboard of back window to regulate quantity of reflux, operation condition is optimized.
Preposition anoxybiotic biological aerated filter device, utilize the big characteristic of volcanics biofilter material lightweight high pitched tune rate specific surface area of BAF, biofilter material is as the carrier of filtration and bio-oxidation, can keep higher biological concentration, therefore having cancelled traditional mud refluxes, and help improving the multiplication rate of nitrifier, the organic waste water of high density is at first through the degraded of oxygen-starved area, remaining organism impacts the generations such as nitrobacteria of aerobic zone and reduces greatly, the bacterium of simultaneously a large amount of generation cycles such as nitrobacteria length is in a large number attached on the biofilter material, keep complete biophase, thereby guaranteed ammonia nitrogen removal ability efficiently.
Preposition anoxybiotic biological aerated filter device particular structure feature and operation characteristic are its basic reasons that can carry out the short-cut nitrification and denitrification denitrogenation.Water inlet is descended along the biofilter material plug-flow, it between the filler space local turbulent flow, on the whole with the accompanying microbial film of each unit filling surface in all exist matrix and dissolved oxygen concentration gradient distribute, also provide condition for microorganism different sites in microbial film of various different ecological type occupies the advantage ecological niche.Generally speaking, as long as satisfy COD/NH
3The just energy denitrogenation of the condition of-N 〉=4, for poor nutritional type waste water, degradable COD ratio is less, therefore at NH
3Under the little situation of-N ascensional range, denitrogenation reluctantly, and synchronous nitration and denitrification are combined, as long as satisfy COD/NH
3The just energy denitrogenation of the condition of-N 〉=1.8 has improved NH greatly
3The removal ability of-N, and have stronger impact resistance.
The present utility model main points are that it is by housing 1, housing 2, water dispensing board 12 and filter 3, supporting seat 4, aeration head 5, volcanics biofilter material 6, back window 7, flashboard 8, effluent weir 9, oxygen-starved area 10, aerobic zone 11, water dispensing board 12, aeration tube 13, backwash water pipe 14 is formed, housing 1 constitutes oxygen-starved area 10 with housing 2, the frame sky of housing 2 is an aerobic zone 11, housing 1 and housing 2 connect by water dispensing board 12 and supporting seat 4, have back window 7 on housing 1 and the housing 2, blast aeration pipe 13 and backwash water pipe 14 are installed in housing 1 and housing 2 bottoms, aeration tube 13, wash water pipe 14 is fixed on the supporting seat 4, non-blocking microporous aeration head 5 is installed, filling volcanics biofilter material 6 in oxygen-starved area 10 and the aerobic zone 11 on the aeration tube 13.Waste water at first enters oxygen-starved area 10, realize the removal of denitrification process and partial organic substances, enter aerobic zone 11 by the bottom back window, current rise under the air blast dynamic action, remaining organism in the sewage is further degraded under the effect of aerobic mycoderm, and by nitrification ammonia nitrogen is converted into nitric nitrogen.A processing back water outlet part is back to oxygen-starved area 10 by back window 7 once more and carries out denitrification process, further removes nitric nitrogen, and another part pass-out mill weir 9 flows away, according to the water outlet effect, and the quantity of reflux of nitrification liquid in can regulating by the flashboard on the back window 78.Be saves energy, the backflow power of interior nitrification liquid is provided by blast aeration, cancels traditional reflux pump; Take up an area of for saving, the utility model adopts " returning " type or concentric-ring pattern structure, realizes that anaerobic-aerobic is integrated, can effectively handle the organic waste water and the high ammonia-nitrogen wastewater of high density.
