Description
Technical field
The present invention relates to a kind of waste disposal plant and treatment process, particularly relate to a kind of integrated in-situ denitrification breeding wastewater biological treatment device and treatment process.
Background technology
Though the development of China's city size livestock and poultry breeding industry starting is late, its growth momentum is very swift and violent, and short more than ten years have reached sizable scale, and continue to be high speed development trend.Because control that poultry industry pollutes and management lag behind developing rapidly of this industry greatly, and lack the basic data and the data of poultry industry contaminated system.When the develop rapidly of aquaculture brought great economic benefit to society, the environmental problem that the breeding wastewater of its discharging brings also was on the rise, and it mainly is ammonia and nitrogen pollution that breeding wastewater pollutes, and had become urban life, trade effluent the third-largest source of pollution afterwards.
Because the pollution problem attention degree for livestock and poultry breeding industry is not enough all the time, livestock and poultry breeding industry hangs down the characteristics of profit in addition, and most of plant does not all just effectively handle directly discharging to waste water of livestock poultry.Along with the aggravation of body eutrophication, people more and more pay attention to the qualified discharge problem of nitrogen in the waste water, phosphorus, and eutrophication problem is one of topmost water pollution problems of facing of the world today.And waste water of livestock poultry has suspended solids height, organic concentration height, characteristics that ammonia nitrogen concentration is high, although Chinese scholars is handled waste water of livestock poultry and carried out a large amount of experimental studies, also has a lot of problems with regard to existing technology application facet.As: adopt the nature treatment system to handle, its treatment effect is subject to the influence of season, temperature and land area, and for the practical situation that China has a large population and a few land, biologic treating technique will be the optimal selection that the limited regional breeding wastewater in soil is handled.But, water pollutant concentration after the anaerobic treatment is still very high, particularly ammonia nitrogen does not have to remove substantially, after entering water body, bring out water body " eutrophication ", cause the disorder of aquatic ecosystem, and can also consume dissolved oxygen, cause water hypoxia, need do the processing of further carrying out denitrogenation dephosphorizing.
In recent years, though the wastewater treatment in China rate improves constantly, the water eutrophication problem that is caused by nitrogen and phosphorus pollution does not only solve, and serious day by day trend is arranged.As seen, the principal contradiction of sewage disposal is changed into the removal of nitrogen, phosphor contaminant gradually by the removal of organic pollutant.This just impels people that traditional activated sludge process is transformed, to improve the clearance of nitrogen, phosphorus.Nitrogen compound (NH
4 +-N and NO
3-N) molecular weight ratio is less, can't remove by adding medicament.In addition, if adopt physico-chemical processes, as utilize membrane separation technique to remove nitrogen compound, it is the most effective that reverse osmosis membrane technology is only arranged, but construction costs and running cost also are very high.Therefore the removal of nitrogen is the difficult point and the emphasis of sewage disposal, and it is the most reasonable feasible to have only the bio-denitrification technology of utilization to be only.On the other hand, the phosphorus compound in the sewage utilizes bioremediation to be difficult for sometimes removing, but can realize satisfied phosphor-removing effect by the dispensing coagulation.Therefore, bio-denitrification technology is the key point of advanced treatment of wastewater.
The technology of current realization denitrogenation is a lot, the most representative technology mainly contains SBR method, A/O method, oxidation ditch process, yet the SBR method can only be applied in small sewage treatment plant, has the pond and holds shortcomings such as lay-up period length, operational management complexity, in the application of municipal sewage plant seldom.And oxidation ditch process belongs to extended aeration technology, has the high shortcoming of capital cost and working cost.The AA/O biological denitrification process is the abbreviation of anaerobic/anoxic/aerobic biological denitrification dephosphorization process, be that the present municipal sewage plant of China uses maximum a kind of denitrification process, denitrification moves under anoxia condition, the nitrated of the removal of carbonaceous organic material and ammonia nitrogen moves under aerobic condition, compare with traditional multi-stage biological denitrification process and to have lot of advantages, but also just ammonia nitrogen is converted into nitric nitrogen, nitrate pollution is not realized real removal.But many researchs only utilize the A/A/O space environment of breeding wastewater, consider denitrogenation separately, lack the research of carbon-nitrogen ratio to the nitrification and denitrification effect, and too high COD is unfavorable for the growth of nitrification and denitrification bacterium, and then influences denitrification effect.As removing, need a large amount of backflow power, by effluent recycling treatment condition are realized denitrogenation by anaerobism to aerobic the transformation to anoxybiotic again, therefore the sewage disposal load is high, running cost is too big, and this is the ubiquitous energy consumption height of present wastewater treatment in China factory's biological denitrificaion, efficient is low and the shortcoming of fluctuation of service.If can effectively reduce backflow, reduce sludge yield, increase the carbon source and the basicity in anti-nitration reaction pond, can guarantee the smooth realization of AA/O biological denitrificaion.
