The utility model discloses when specifically using, the dry-wet separating centrifuge can reduce the content of suspended solid in the excrement is dirty, and after solid-liquid separation, the chemical oxygen demand in the sewage can descend the certain proportion, has created the condition for efficient anaerobism technology, if chemical oxygen demand or suspended solid are too high, then probably block up high efficiency filter or sludge blanket. Because of the reduction of the chemical oxygen demand, the load of anaerobic treatment is reduced, the production of sludge is reduced, the volume and the occupied area of the anaerobic treatment device are reduced, and the manufacturing cost is reduced.

The air floatation zone utilizes highly dispersed micro-bubbles as carriers to remove hydrophobic particles in the adhesion wastewater, the micro-bubbles and the particles are regarded as a whole, the whole density of the whole is less than that of water, and the whole floats to the water surface, so that the solid-liquid separation process is realized, the suspended solid in the sewage after air floatation treatment is greatly reduced, a certain denitrification effect is achieved, the chemical oxygen demand can be reduced by a certain proportion, and in the air floatation process, proper chemical agents are often required to be added, so that the air floatation effect is improved. The main additives are coagulant and coagulant aid, the coagulant: various inorganic or organic high molecular coagulants can change the hydrophilic performance of suspended particles in sewage, and can flocculate fine particles in sewage into larger floccules to adsorb trapped air bubbles and accelerate the floating of the particles. Such as aluminum sulfate, ferric chloride, polyaluminum chloride, coagulant aids: increasing the water tightness of the surface of the suspended particles to increase the floatability of the particles, such as polyacrylamide.

Because the aquaculture wastewater belongs to 'three-high' wastewater with high organic matter concentration, high N, P content and high harmful microorganism quantity, the anaerobic technology becomes an indispensable key technology in the treatment of the feces of livestock and poultry farms. For the high-concentration organic wastewater in a farm, a large amount of soluble organic matters can be effectively removed at a lower operation cost by adopting an anaerobic digestion process, the removal rate of chemical oxygen demand reaches a high proportion, and infectious germs can be killed.

In the aerobic zone, the concentration of organic matters is greatly reduced, but a certain amount of organic matters and higher NH3-N still exist in the sewage treatment equipment. In order to further oxidize and decompose the organic matters and simultaneously ensure that the nitrification can be smoothly carried out under the condition that the carbonization is finished, an aeration fan is arranged in an aerobic zone, and aerobic microorganisms and autotrophic bacteria (nitrifying bacteria) exist in an aerobic section, wherein the aerobic microorganisms decompose the organic matters into CO2 and H2O; under the condition of sufficient oxygen supply, NH3-N (NH4+) is oxidized into NO3 by the nitrification of autotrophic bacteria, the NO is returned to an anoxic section by reflux control, and NO 3-is reduced into molecular nitrogen (N2) by the denitrification of heterotrophic bacteria under the anoxic condition, so that the ecological circulation of C, N, O is completed, and the sewage is harmless.

The settling zone is used for carrying out solid-liquid separation to remove suspended sludge peeled off from the biochemical zone, so that the sewage is really purified. The sludge is discharged to the sludge area at regular time by adopting a pump, and the sludge reflux device is arranged, so that part of the sludge is refluxed to the anaerobic area for nitrification and denitrification, the generation of the sludge is reduced, and the removal of ammonia nitrogen in the sewage is facilitated.

Chlorine dioxide is added into the clear water area for disinfection, so that the effluent quality meets the requirement of sanitary index and is discharged out after being qualified.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and equivalents can be made without departing from the spirit and scope of the invention as defined by the appended claims.
