In recent years, livestock and poultry breeding in China develops rapidly, with the increase of the material demand of people and the promotion of vegetable basket engineering in China, the consumption of eggs, milk and meat is promoted powerfully, the agricultural industrial structure is adjusted, the livestock breeding is developed rapidly, the traditional breeding mode is broken gradually, the agricultural industrialization process is accelerated, the agricultural structure is adjusted correspondingly, and the rapid development of the livestock and poultry breeding is promoted. According to statistics of the national statistical administration, the total meat yield in 2015 is 8625 ten thousand, and compared with the meat yield in 2010, the total meat yield is increased by 8.12% and increased by 1.62% every year. The production of each livestock and poultry product lasts for years and is at the top of the world. The specific gravity of the animal husbandry output value in the total output value of the first industry steadily rises, the total output value of the animal husbandry in 2016 years is 3122.99 hundred million yuan and accounts for 28.6 percent of the total output value of the first industry, the per capita meat accounts for 61.76 kilograms, the income of directly engaging in the livestock and poultry breeding accounts for 1/6 of the cash income of the family agricultural operation, the supporting effect of the animal husbandry on agriculture and rural economy is enhanced, the animal husbandry becomes a supporting industry driving the rural development, and the animal husbandry output value plays an increasingly large role in promoting the steady increase of the national economy. The production of livestock and poultry breeding, which has been greatly increased in order to meet the demand of people, cannot be uniformly distributed all over the country, and the livestock and poultry breeding is being converted from 2 billion farmer breeding to a large-scale centralized farm.

The poultry breeding wastewater has the following characteristics: 1) COD, SS, NH₃high-N concentration; 2) large water quantity and poor water quality condition; 3) contains a large amount of pathogenic bacteria accompanied by malodor; 4) high treatment difficulty, high technical process requirement and the like. The first pollution source census bulletin shows that livestock and poultry breeding is the main source of agricultural pollution in China, and the discharge amounts of COD, TN and TP account for 96%, 56% and 38% of the total discharge amount of pollutants of agricultural sources. According to related research 2015, the livestock bred in China generate 27 hundred million t of animal wastes which are about 3.5 times of industrial solid wastes every year, and the animal wastes pollute cultivated lands, water bodies, atmosphere and organisms, cause soil hardening, water body eutrophication, cause diseases such as respiratory tract infection and the like, destroy the ecological environment and influence the health of human bodies. Pathogenic bacteria and other microorganisms contained in the aquaculture wastewater enter a natural water body and are transmitted along with surface runoff and underground runoff to harm the health of human beings and animals; untreated livestock and poultry wastewater mostly directly irrigates farmlands to cause the water permeability of farmland soil to be reduced, and influences the growth of crops and even causes the death of the crops; trace heavy metals and antibiotics added in the livestock and poultry feed cannot be completely absorbed and digested by animals, and the heavy metals in the soil are detected along with the heavy metal pollution caused by irrigating farmlands; the crops carrying heavy metals and animals carrying pathogenic bacteria are also finally enriched on human bodies through food chain transmission, so that the treatment of the livestock wastewater without increasing the grasping time is urgent.

Disclosure of Invention

The utility model aims to solve the problem that antibiotics and heavy metals are difficult to effectively get rid of simultaneously in the beasts and birds breed waste water, provide a novel high-efficient device of handling beasts and birds breed waste water of mobile vertical baffling formula. The utility model comprises a water inlet (1) at the bottom of the left side, a water outlet (3) at the upper part of the right side, a novel particle electrode (2) of 5mm attached organisms, anode plates (5) and cathode plates (6) which are alternately arranged at equal intervals, and an organic glass baffle plate (4) with uniform holes. The anode is provided with an organic glass partition plate which is flush with the anode and is directly communicated with the bottom of the device, the cathode is provided with an organic glass partition plate which is flush with the upper part of the device and is arranged on the supporting layer at the lower part of the device, and water flow in the whole process flows through the particle electrode and the cathode and the anode from left to right in an S shape; the bottom layer clapboard is a supporting layer, and the lower part of the supporting layer is provided with an aeration pipe pipeline which runs through the whole device and has uniform pores for uniform gas distribution, thereby ensuring uniform oxygen supply to microorganisms on one hand, ensuring the existence of advanced oxidation on the other hand, and accelerating the process of degrading antibiotics. Livestock and poultry breeding wastewater is conveyed into the first lattice of the device after being pretreated conventionally in the early stage through the inflow pump, and water flows into the first lattice of the wastewater treatment device from bottom to top and sequentially flows into the next region from the upper part of the anode and the lower part of the cathode through the electric-biological coupling device. The antibiotic is more than the area close to the anode and is decomposed into small molecules through advanced oxidation, and the small molecules are finally treated by microorganisms, and the heavy metal is more than the area of the cathode and is reduced and removed. The livestock and poultry breeding wastewater flows through the S-shaped flow device and finally flows out through the upper right water outlet. The device successfully couples the electrochemical technology with the biological treatment technology, introduces an electric field on the basis of the biological wastewater treatment process, and transfers electrons to the particle electrodes attached with the biological membrane through the electrode plates arranged at equal intervals, so that each particle electrode becomes a microelectrode, and the activity of microorganisms is stimulated while the advanced oxidation capacity is expanded. Under the stimulation effect of current, nutrient substances can effectively accelerate passing through cell membranes, promote the growth and the reproduction of microorganisms, and further more quickly and effectively remove antibiotics and heavy metals in water. Experiments prove that under the influence of an electric field, the microorganism can possibly generate electrocatalysis, activate or enhance the dehydrogenase activity of the microorganism and improve the processing capacity of the microorganism on antibiotics; substances which are difficult to biodegrade are converted into biodegradable intermediate products under the electrochemical action, and although the intermediate products cannot be oxidized continuously under the electrochemical action, the intermediate products can be directly used as a carbon source or an energy source in the growth process of microorganisms, so that the removal of antibiotics is realized; the quantity of microorganisms is increased under the stimulation of electricity, so that the extracellular polymeric substance EPS is increased, and the adsorption of the extracellular polymeric substance to the heavy metal and the reduction of the cathode to the heavy metal greatly improve the removal rate of the heavy metal. In addition, the filter material can also be used as a filter medium to intercept suspended solids and newly generated biosolids in water, thereby omitting a secondary sedimentation tank commonly used in other biological treatment methods. And the separator between the filter material and the electrode plate is convenient for taking out the cathode and the anode on one hand, and also prevents the electrode plate from directly contacting with the filter material on the other hand, thereby avoiding the generation of short-circuit current. When the current efficiency is reduced due to the large amount of attachments on the cathode and anode of the device, the aeration amount can be increased and the electrodes connected with the cathode and anode plates can be exchanged to effectively clean the electrode plates, and the movable electrode plates can be taken out of the device for cleaning when necessary. Due to the addition of the factors, a good solution is provided for the problem that the existing livestock and poultry breeding wastewater has high content of heavy metals and antibiotics and is difficult to effectively and simultaneously remove by the conventional common sewage treatment process. In the aspect of economic benefit, because particle electrodes can be filled in the middle of the device, the electrode distance is reduced, the mass transfer distance is shortened, the mass transfer efficiency is well improved, the current efficiency is higher, the pollutant removal capacity is higher, the consumption is reduced, and the economic benefit is good.
