PROCESS FOR BIOGASIFYING ORGANIC WASTE WITH HIGH EFFICIENCY THROUGH DENITRIFICATION OF DIGESTION WASTEWATER BY USING DIGESTION GAS AND PREPARATION OF CHAR OF DIGESTED SLUDGE

摘要

The present invention relates to a biogasification process for high-concentration organic waste and, more specifically, to a biogasification process for high-concentration organic waste, the process receiving organic waste, allowing same to sequentially pass through a pretreatment process, an anaerobic digestion process, a digested sludge process and a wastewater treatment process, and then discharging same to a sewage treatment plant and the like, and converting digested sludge, which is to be generated during the processes, into biochar through a carbonization process so that same can be reused in the anaerobic digestion process and a process using digestion gas. The present invention injects, into an anaerobic digestion tank of the anaerobic digestion process, biochar obtained by converting, through a drying process, a carbonization process and a desalting process, the digested sludge to be discharged from a compositing dehydrator of the digested sludge process so that digestion efficiency is improved, injects same into a purification facility of the process using digestion gas so that an activated carbon adsorption column can be replaced, and further provides a methane oxidation reactor inside of an aeration tank of the wastewater treatment process so that high-concentration ammonia can be removed.
