NOVELTY - Treating livestock and poultry breeding wastewater, comprises e.g. collecting the wastewater using a collection reservoir and then sending into a concentration tank in front of a solid and liquid separator through a sludge pump, adding polymeric ferric sulfate flocculant by an automatic medicine feeder to flocculate, separating the wastewater by the belt type solid and liquid separator and then fermenting, introducing into next treatment process, and filtering the separated wastewater by quartz sand and then entering into upflow anaerobic sludge blanket anaerobic device.    USE - The method is useful for treating livestock and poultry breeding wastewater.    ADVANTAGE - The method allows economical treatment of livestock and poultry breeding wastewater with high efficiency and less energy consumption in an eco-friendly manner.    DETAILED DESCRIPTION - Treating livestock and poultry breeding wastewater, comprises: (1) collecting the wastewater using a collection reservoir and then sending into a concentration tank in front of a solid and liquid separator through a sludge pump, adding polymeric ferric sulfate flocculant by an automatic medicine feeder to flocculate, separating the wastewater by the belt type solid and liquid separator and then fermenting, and introducing into next treatment process; (2) filtering the separated wastewater by quartz sand, entering into upflow anaerobic sludge blanket anaerobic device with hydraulic retention time of 8 hours, flowing and mixing the wastewater with the microorganism, decomposing organic substance in the wastewater using microorganism and then transforming into marsh gas, releasing the marsh gas in a form of bubble, rising up the bubbles to form bigger bubble, attaching an upper part of a reactor with a solid, liquid and gas separator, rising the mixed solution with large amount of bubbles to a bottom of the separator, separating the gas and then introducing into a gas chamber and flowing out by a guide pipe, and entering the solid and liquid mixture into a separating area and then falling down because of the gravity into a reacting area for reaction; (3) clearing the wastewater in the separating area and then pumping into a closed circuit ultrasonic generating device by a supercharge pump with hydraulic retention time of 1 hours, flowing the water under the reaction of a high pressure ultrasonic cavitation, continuously increasing the pressure and air action, rising the super zero water and then introducing from a left side of a porous diffuser reactor and mixing with a right ozonized air, providing enough oxidant for the super zero water by ozone to fully react and then transforming into carbon dioxide and water, transferring the sulfur and phosphor into sulfuric acid salt and phosphoric acid salt and transforming nitrogen into nitric acid radical and nitrous acid radical ion or nitrogen, arranging a closed device with a three phase separator, filtering salt substance and other degradable organic substance after reaction and then removing, and introducing the gas generated by reaction into a gas chamber and then guiding with upflow anaerobic sludge blanket; (4) filtering the wastewater from the closed three phase separator, entering into a ozone tower plate reactor to perform oxidization and then sterilizing, and decoloring and removing peculiar smell; and (5) filtering by the active carbon and zeolite to purify the water to meet the standard emission.
