Abstract
The utility model discloses a sewage treatment device for removing high-concentration ammonia nitrogen. The device comprises a reaction tank. A water inlet and an overflow hole are respectively arranged on two side walls of the top of the reaction tank. Baffling plates arranged in a staggered manner are arranged in the inner cavity of the reaction tank. A biological film filling material is filled in the reaction tank. An air pipeline is arranged in the reaction tank. A transverse spray pipe is communicated with the lower end of the air pipeline. An aeration head is arranged on the surface of the spray pipe. The device disclosed by the utility model is formed by improving the A2/O method and combining with the biological film method. The device can generate an enzyme system by itself. Supplement is unnecessary under normal conditions.
Description
Technical field
The utility model relates to sewage treatment area, relates in particular to a kind of waste disposal plant that removes ammonia nitrogen in high density of terminal WWT in the Ammonia Production.
Background technology
The sewage treatment process of removal of ammonia and nitrogen at present commonly used mainly contains A/O method, A
2/ O method, A
2/ O
2Method, SBR method, biomembrance process etc., the A/O method is an activated sludge process early, develops to the ammonia nitrogen treatment of Organic Wastewater specially, and it is made up of anaerobic denitrifying pond and aerobic nitrification tank, and the treatment of ammonia nitrogen effect is general, A
2/ O method and A
2/ O
2Method is on A/O method basis, to improve to form, and is to accomplish the denitrogenation dephosphorizing reaction through anaerobism and environment aerobic, the anoxic alternate, and effect is better in the treatment of high concentration ammonia nitrogen waste water; Invest greatlyyer, running cost is higher, and the SBR method claims that again preface criticizes intermittent activated sludge process; Its technological core is the sbr reactor pond; Sewage is accomplished operations such as reaction, deposition, draining and eliminating excess sludge in this reaction tank, the processing water yield must adopt a plurality of unit combination when big, and the water inlet of reaction tank, aeration, spoil disposal change frequent; Labor management is difficulty; Automatically control degree is had relatively high expectations, and energy consumption is higher, biomembrance process be develop over past ten years, with activated sludge process a kind of aerobe treatment technology arranged side by side.Different choice at aspects such as microbial strains, BAF, filtrates all will directly influence the processing power of biomembrance process to sewage.
The utility model content
The purpose of the utility model content provides a kind of waste disposal plant that removes ammonia nitrogen in high density, at A
2Improve on the basis of/O method and the exploitation that combines with biomembrance process forms, can produce enzyme system voluntarily, need not to add under the normal circumstances.
The technical scheme of the utility model is following:
A kind of waste disposal plant that removes ammonia nitrogen in high density; Include reaction tank, have water-in, riser on the two side, top of said reaction tank, be provided with staggered traverse baffle in the reaction tank inner chamber; Be filled with biofilm packing in the reaction tank; Be provided with air line in the reaction tank, the lower end of air line is communicated with horizontal jet pipe, and the surface of jet pipe is provided with aeration head.
Described reaction tank top is provided with access opening.
The beneficial effect of the utility model is following:
The level of automation of the utility model is high, and is stable, convenient operation and management, and pollutant removing efficient such as COD, ammonia nitrogen are high, strong shock resistance.The COD decreasing ratio reaches 95%, and ammonia-nitrogen removal rate reaches more than 92%.Can guarantee that effluent quality reaches national grade one discharge standard., the sewage behind the equalizing tank all adopts from stream mode, and quantity of reflux is little, and energy consumption is low.High-efficiency strain is strong to toxic substance and soda acid tolerance, need not to add soda ash and carbon source under the long service life, normal circumstances, and this process unit mud growing amount is few, does not produce the harm of sludge bulking.Running cost can be lower than same device about 50%.
