Background technology
In recent years, with China's structure of agricultural production adjustment and agriculture industrialization propulsion, scale, intensive livestock and poultry support
Grow industry and be able to fast development, but a large amount of livestock breeding wastewaters of the thing followed cannot be handled effectively.Contain in livestock breeding wastewater
There are a large amount of organic pollutions, pathogenic microorganism and bacterium, color is deep, stink is dense, COD is up to 5000-40000mg/l, ammonia nitrogen is high
1000-3000mg/l, suspension is high, the exceeded decades of times of SS.Pollution from livestock and poultry turns into after industrial pollution, domestic pollution
The third-largest pollution sources, the sewage of high concentration is discharged into rivers and lakes, causes surface water, groundwater quality constantly to deteriorate, so as to make
Into severe environmental pollution, the healthy of people is directly endangered, the development of cultivation industry is also seriously constrained.
Existing handling process mainly uses anaerobic-aerobic group technology, although can effectively remove the COD of waste waterCr、BOD5
And NH3- N, but the chromaticity removing effect of waste water is not obvious, livestock breeding wastewater passes through after Aerobic Process for Treatment, and second pond goes out
Colority of water is still very high, reaches 500-2000 times (extension rate method), COD is generally 200-800mg/l, it is impossible to reach that depth takes off
The effect of color.Although existing discharge standard does not make requirement to colourity, effluent color dilution is too high very big shadow to water quality, perception
Ring, also influence the environmental benefit and social benefit of plant.Using bleaching agent, (Pig farm wastewater decolourizes and deodorization Wang Zhi tri- et al.
Research ecological sciences, 1993,2,113-116) decolouring research is carried out to the waste water of plant, have certain effect, but medicament
Consumption is excessive, and secondary pollution is heavier.
Ozone has extremely strong oxidation susceptibility, and being can be direct in a kind of oxidant of efficient non-secondary pollution, oxidizing process

Low stain load and depth remove the purpose of chroma in waste water, and ozonation technology has that reaction speed is fast, simple to operate, run into
The advantages of this is relatively low, is gradually used widely.The application aspect of current ozone oxidation depth decolorization waste water of livestock poultry is still deposited
In some problems：
1) fluidised catalyst filling is in the inside of reactor, and catalyst is easily lost in the flowing of dampening, weakens
Reaction efficiency, and add operating cost；
2) ozone reaction structures typically use tower reactor, on the one hand relatively build cost high, in addition it is also necessary to which supporting consolidates
Determine device；Another aspect device structure low intensity, security is inadequate, easily by external interference；
3) ozone dosage is easily excessive, and cost is too high；On the other hand reacted substantial amounts of ozone tail gas exhaust emission
Environment；
4) before reactor water inlet, variation water quality is larger, when raw water quality changes, can influence follow-up catalysis
Reaction effect；Because equipment fault stops water inlet experiment may also can be caused to be carried out continuously.
