METHOD FOR PRODUCING ALTERNATIVE CARBON SOURCES USING WASTE OF FOOD LEACHATE

摘要

The present invention relates to a method for manufacturing an alternative carbon source using food waste leachate. The purpose of the present invention is to provide a carbon source for treating wastewater generated from a steel plant etc. at a low cost and to treat wastewater in a steel plant etc. at a low cost by securing a carbon source using waste as starting materials. The method for manufacturing an alternative carbon source using food waste leachate according to the present invention comprises: a solid screening step for screening foreign materials in a solid form included in food waste leachate; a fermentation step for activating useful microbes by anaerobically fermenting the food waste leachate in a liquid state having solids screened in the solid screening step and removing organic matters by aerobically fermenting the food waste leachate; a flow control step for manufacturing an alternative carbon source having a C/N ratio thereof kept constant by controlling the flow of a fermented solution passed through anaerobic fermentation and aerobic fermentation in the fermentation step; and an afterripening step for ripening the alternative carbon source having a C/N ratio thereof kept constant by the flow control step.
