Abstract
Disclosed herein is a method for zero-discharge treatment of high-concentration organic wastewater by mixing sludge with high-concentration organic wastewater. The sludge is biodried sludge prepared by a method including preparing a sludge mixture consisting of belt-pressed sludge and dried sludge; and collecting the sludge mixture when its temperature finally becomes stable by returning to room temperature. The high-concentration organic wastewater used contained small particles of pulverized food waste having a diameter of 1 mm or less. The treatment was performed by decomposing the organic materials using microorganisms contained in the sludge via metabolism, followed by water evaporation caused by the metabolic heat generated by the decomposition of the organic materials, in which the microbial metabolism was performed under an aerobic condition.
