The processing method for waste water of food waste and organic acid

The present invention relates to a non-discharge method of treating wastewater of food waste and organic sludge. The non-discharge method of the present invention comprises: an injection process (a first process) of injecting collected various wastes into an injection hopper; a pulverization and selection process (a second process) of pulverizing the wastes injected in the first process in a pulverizing separator and selecting adulterations from the wastes; a storage process (a third process) of storing the wastes pulverized in the second process in a pulverized material storage hopper; a mixing process (a fourth process) of mixing the wastes stored in the third process with an organic acid to annihilate saprogenic bacteria, and mixing an excipient and humic acid with the saprogenic bacteria-annihilated wastes in a mixer; a drying process (a fifth process) of drying the mixture obtained in the fourth process in a dryer; an odor removal process (a sixth process) of burning odor and combustion gas generated during drying in the fifth process in a primary bottom-up deodorization furnace, and burning odor and combustion gas which have not been burned in the primary bottom-up deodorization furnace in a secondary top-down deodorization furnace, thereby removing odor and remained wet vapor in a wet scrubber; and a selection process (a seventh process) of injecting the dried material dried in the fifth process into a vibration separator to select adulterations. According to the present invention, the non-discharge method not only enables the wastes to be supplied to a livestock farmhouse as a feed, but also enables the wastes to be recycled as a carbide product such as a moisture absorbent, a pH adjusting agent and the like since a fertilizer or carbide product treated by the above-mentioned processes is environmentally friendly by removing odor and lowering moisture content in the processing procedure without discharging wastewater produced from wastes including food waste to the outside, and the wastes are reborn as a high quality feed by passing through several times of the selection processes. 본 발명은 음식물쓰레기 및 유기성오니류의 폐수무방류 처리방법에 관한 것으로, 수거한 각종 폐기물을 투입호퍼에 투입하는 투입공정(제1공정)과, 상기 제1공정에서 투입된 폐기물을 파쇄선별기에서 파쇄하고, 협잡물을 선별하는 파쇄선별공정(제2공정)과, 상기 제2공정에서 파쇄된 폐기물을 파쇄물저장호퍼에 저장하는 저장공정(제3공정)과, 상기 제3공정에서 저장된 폐기물에 유기산을 혼합하여 부패균을 사멸시킨 후 부형제, 부식산을 혼합기에서 혼합하는 혼합공정(제4공정)과, 상기 제4공정에서 혼합된 혼합물을 건조기에서 건조하는 건조공정(제5공정)과, 상기 제5공정에서 건조시 발생된 악취 및 연소가스를 1차 상향식 탈취로에서 연소시킨 후, 상기 1차 상향식 탈취로에서 미연소된 악
