METHOD FOR TREATING GAS-TREATMENT DRAINAGE, GASIFICATION APPARATUS OF CARBONACEOUS MATERIAL, AND METHOD FOR TREATING CARBONACEOUS MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide: a method for recovering and utilizing components such as benzene, phenol, oil content, dust or the like, which cannot be utilized of their calorific value if nothing is done, by simply processing the generated waste water; an apparatus therefor; and a method for treating a carbonaceous material.SOLUTION: There are provided a method for treating gas-treatment drainage in a method of combined production of the combustible gas and a carbonized matter 4, comprising: generating pyrolysis gas, tar 5 and the carbonized matter 4 by pyrolyzing a carbonaceous material 1 in a pyrolytic furnace 2; reforming the pyrolysis gas and tar 5 in a reforming furnace 6 to produce combustible gas; cooling and dust-removing the combustible gas, and then removing the interference of the combustible gas to perform purification; mixing the waste water generated at the gas purification with the carbonized matter 4; and combusting the resulting slurry or powdery raw material for combustion facility. An apparatus to be used for this treatment method, and a method for treating the carbonaceous material 1 to produce the slurry or powdery raw material for combustion facility are also provided.
