Description
Technical field
The present invention relates to the treatment system and the treatment process of waste water of livestock poultry, say so more specifically a kind of two-stage anaerobic-tower type filter chamber livestock/poultry wastewater treatment system and treatment process.
Background technology
Along with the development of China's intensive culture industry, a large amount of feces of livestock and poultry waste water that plant produces are more and more paid close attention to by people the pollution of environment.Plant's waste water not only corrodes a large amount of farmlands, and severe contamination human air, water body of depending on for existence.The pollution of plant's waste water is the most serious with the large scale of pig farm field, and 1 pig produces sewage 2.5t/a approximately, but nearly 300,000 t/a of ten thousand pig farm effluent sewerages amount to ammonia 300～400t, phosphorus 320～570t.Along with the continuous expansion of pig farm scale, the continuous increase of quantity, plant's sewage can't be digested by the soil, the dirty a large amount of foul smell that produce of excrement are released in the air, do not add the sewage of handling and being discharged natural water has been caused large-area pollution, how efficiently handling plant's sewage has become the important topic that researcher faces.
Waste water of livestock poultry possesses the high distinguishing feature of organism, suspended substance and ammonia nitrogen concentration, contains a large amount of organism (COD in feces of livestock and poultry and the waste water
Cr), pollutent and foul smelling such as N, P, K, SS and pathogenic bacterium.Table 1 has provided certain livestock and poultry farm waste water quality situation:
Table 1: certain livestock and poultry farm waste water quality
The concentrated discharging of undressed high concentrated organic wastewater, the dissolved oxygen in the mass consumption water body makes the water body blackening smelly, and nutrition such as N, P impels body eutrophication in the water, or nitric nitrogen or nitrite nitrogen concentration in the underground water are increased.At present, aerobic, anaerobism and aerobic+anaerobic technique are mainly adopted in the processing of intensive culture field sewage, can effectively remove COD
CrAnd total suspended matter, but the effect that nitrogen, phosphorus are removed is still waiting further research.
Filler is one of core of technology of biological membrane in the water treatment, and its performance all has a direct impact efficient, energy consumption, stability and the reliability of wastewater treatment process.Biomembrance process is exactly that microorganic adhesion is bred on the surface of solid packing, and filler is a microorganism carrier, and microorganism forms microbial film on filler, and microbial film absorbs the material in the sewage in metabolic processes, realize the degraded of sewage.Therefore, carrier performance is the core that the biomembrance process of sewage is handled waster water process, utilizes mud to prepare the ceramics filling biofilm and can efficiently remove COD of sewage

Cr, BOD
5The removal ability of ammonia nitrogen and TP is all more than 90%, the removal ability of TN only is 15.7%, the nitrate nitrogen cumulative concentration is that influent concentration exceeds 1 order of magnitude in the water outlet, surpass 300mg/L (Shao Fang, Zhang Dingguo. mineralized refuse bioreactor is handled the experimental study of waste water of livestock poultry. Techniques and Equipment for Environmental Pollution Control .2002,3 (2): 32-36.).The cumulative nitrate nitrogen is mainly derived from the nitrated of ammonia nitrogen in the water outlet, and the removal of nitrate nitrogen mainly realizes by denitrification.But the mineralized waste filler fill to be piled up and to be higher than behind the 1.5m behind the operation 1-2, and the filler phenomenon of blocking can take place.
Existing technology mainly contains: (1) SBR method, but the hydrolysis of its short period of time (HRT=2.0～6.0h) TP in the piggery waste is had removal effect preferably.Clearance reaches 55.3%, and is relatively poor to the removal effect of nitrogen, and clearance 22.3% (Deng Liangwei. hydrolysis-SBR fourth skill treatment scale piggery waste research. Chinese water supply and drainage, 2001,17 (3): 8-11).(2) up-flow anaerobic sludge blanket-activated sludge process is discovered, adopts acidication-USR-activated sludge process to handle milk cattle cultivating waste water, obtains treatment effect preferably.USR is the upflow type anaerobic sludge sump. behind the waste water process USR pond. in the aerobic aeration biochemical system, by the control aeration time, improved denitrogenation dephosphorizing efficient, ammonia nitrogen and total tp removal rate are respectively: 89% and 60% (Chen Liang, Yang Bin, Li Huan, etc. the design and the commissioning test of milk cattle cultivating field waste water treatment engineering. Chinese water supply and drainage, 2007,33 (10): 71-73).
China mainly adopts the combination process of anaerobic-aerobic to the processing of breeding wastewater, uses through experimental study and engineering to confirm COD
CrAnd SS is very effective, but to denitrogenation dephosphorizing aspect DeGrain.Waste water of livestock poultry concentration of nitrogen and phosphorus height in actual applications. be difficult for removing, and have problems such as fund is few, the industry benefit is low, thereby nitrogen phosphorus treatment effect is not good, sewage can not be realized qualified discharge.Therefore, be present technical barrier on the removal method of low operating cost, high efficiency denitrogenation dephosphorizing.
