TREATMENT METHOD OF HIGH-CONCENTRATION REFRACTORY ORGANIC MATTER IRRADIATED USING CONTINOUS STIRRED TANK REACTOR

摘要

The present invention provides a method for processing a high-concentration non-biodegradable organic material including: a first step of irradiating the high-concentration non-biodegradable organic material with radiation; a second step of generating organic acid and methane by inserting the high-concentration non-biodegradable organic material, irradiated with radiation in the first step, in a high temperature reactor which is a continuous stirred tank reactor (CSTR) including anaerobic microorganisms and maintaining hydraulic retention time of 4-15 days; and a third step of inserting the high-concentration non-biodegradable organic material, processed by the second step, into a medium temperature reaction tank which is a CSTR including anaerobic microorganisms and processing remaining organic acid and remaining non-biodegradable organic materials. According to the present invention, the method for processing a high-concentration non-biodegradable organic material is a technology for pretreating the high-concentration non-biodegradable organic material wherein the high-concentration non-biodegradable organic material is transformed into a material, which can be easily biodegraded in following process by transforming the high-concentration non-biodegradable organic material into a biodegradable material by using irradiation of radiation; and thus the high-concentration non-biodegradable organic material can be more efficiently decomposed.
