Description

A kind of decoloration device of livestock breeding wastewater
Technical field
The utility model is related to a kind of decoloration device of livestock breeding wastewater, belongs to field of waste water treatment.
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 Degrade or produce the organic matter in a large amount of strong oxidizing property free radicals, such as hydroxyl radical free radical (OH) decomposition water indirectly, reach drop 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.
Utility model content
The utility model makes in waste water in order to solve the above technical problems, provide a kind of decoloration device of livestock breeding wastewater Organic matter fully contact and degraded with ozone.
The technical solution of the utility model is to provide a kind of decoloration device of livestock breeding wastewater, including balancing reservoir, reaction Device, ozone generator and exhaust gas processing device, reactor are the two-stage ozone reactor being serially connected, respectively first order ozone Reactor and second level ozone reactor;The top of every grade of ozone reactor is equipped with water inlet and gas outlet, and bottom is equipped with Delivery port and air inlet, air inlet are connected with ozone generator, and gas outlet is connected with exhaust gas processing device, first order ozone The water inlet of reactor is connected with the delivery port of balancing reservoir;Multi-layer fixed-bed catalyst is provided with the inside of every grade of ozone reactor Layer, the bottom of every grade of ozone reactor is provided with aerator.
Further, in the inside of every grade of ozone reactor provided with 2-10 layers of fixed-bed catalytic oxidant layer.
Further, in the inside of every grade of ozone reactor provided with 4-8 layers of fixed-bed catalytic oxidant layer.
Further, the aerator is ozonation aerated disk.
Further, the shell of the balancing reservoir and reactor is made up of concrete.
Further, back washing device is set below every grade of ozone reactor.
Further, it is equipped with water pump on the water inlet pipe of balancing reservoir and reactor.
Further, the height of every grade of ozone reactor is more than 2m.
Urge by the way that by catalyst filling fixed bed, loaded on inside ozone reactor, livestock breeding wastewater is from ozone reactor top Portion enters, and ozone gas enters from reactor bottom.When ozone flows through catalyst filling layer, in the catalytic action of catalyst Under, the hydroxyl radical free radical for producing strong oxidizing property, hydroxyl radical free radical and the colour developing radical reaction in livestock breeding wastewater are decomposed, is reached The effect that depth is decolourized, the air water reverse flow used enhances the mass transfer between gas, liquid, solid three-phase, improves ozone oxidation Efficiency;Multi-layer catalyst packing layer in fixed bed inside multistage ozone reactor can reach expected catalytic effect, Also it can guarantee that catalyst is not lost in the decrease in turn resulting in cost increase and experiment effect with current;Meanwhile, lead to smelly by bottom The mode of oxygen, can preferably affect the flowing of livestock breeding wastewater, increase turbulences effect, improve the mass-transfer efficiency of water body, The abundant haptoreaction of oxidizing species for making hardly degraded organic substance be produced with ozone oxidationization.
Reactor of the present utility model uses concrete structures, builds cost relatively low, it is not necessary to supporting fixing device, High-strength structure ensures the security performance of structures.Reactor and connected device easily realize one by concrete structure Bodyization is designed, and multiple devices is integrated in one, floor space is small.
The utility model is enhanced the treatment effect of waste water, set inside ozone reactor by two-stage ozone reactor Multi-layer fixed-bed catalyst layer, can avoid the loss of catalyst, can also improve the catalytic reaction efficiency of waste water.
