摘要： 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.

摘要： The present invention includes: a laundry wastewater tank that temporarily stores laundry wastewater from a plant facility; a biological treatment tank in which the laundry wastewater from the laundry wastewater tank is aerated and mixed with activated sludge; a treated water tank that stores the treated laundry wastewater that has been biologically treated; and a treatment preparation supplying device that supplies a laundry wastewater biological treatment preparation to the biological treatment tank. The laundry wastewater biological treatment preparation is introduced when a change in water quality that deteriorates the biological treatment in the biological treatment tank is detected. Thus, biological treatment can be performed stably.

摘要： An apparatus and method for selecting, retaining or bioaugmenting solids in an activated sludge process for improving wastewater treatment using screens. The screens can be used to separate and retain solids based on size, compressibility or shear resistance. The screens are used to separate and select slow growing organisms, faster settling organisms, or materials added to absorb, treat or remove constituents in the activated sludge process. A swapping screen arrangement provides another means of selecting various particles. The exposed shear rate or time, particle compression, or SRTs can be adjusted manually and/or automatically in response to detected readings from an instrument such as a spectrophotometer or other optical approaches to optimize selection of organisms. The present disclosure may be configured as an activated sludge system operated at different solids residence times (SRT) for different solids fractions allowing slow growing organisms to get established in competition with faster growing organisms or aggregates thereof.
