SAFE GASIFICATION EMISSION SYSTEM FOR PERFORMING SAFE TREATMENT OF WASHED OBJECT BY WASHING TREE OR THE LIKE AND OTHER CONTAMINANT CONTAMINATED BY RADIOACTIVITY GENERATED BY NUCLEAR ACCIDENT TO SAFE REFERENCE VALUE OR BELOW BY USING WATER OF TEMPERATURE OF 28°C OR BELOW AND EMITTING GASIFIED WASHING WATER INTO AIR TO RETURN WASHING WATER TO NATURE BY PRECIPITATING AND DECONTAMINATING WASHING WASTE WATER DRAINED BY WASHING AND GASIFYING WASHING WATER AFTER WASHING WITH REVERSE OSMOSIS MEMBRANE WASHING WATER BY USING GASIFICATION MACHINE

摘要

PROBLEM TO BE SOLVED: To provide a safe treatment system which performs decontamination treatment by washing radioactive materials attached to waste incineration ash, trees and other contaminant contaminated by radioactive materials to a safe reference value determined by a nation and performs treatment of washing waste water discharged by the washing.;SOLUTION: Washing operation is safely subjected to radioactive materials by washing by using water of the water temperature of 28.4°C or below of cesium of 137 having the lowest melting point temperature of radioactive materials. Washing waste water discharged by the washing operation is gasified by a gasification machine which repeatedly performs a precipitation operation process in a precipitation pool of a water purification facility by using specific gravity of materials, treats a small amount of contaminated precipitate or the like precipitated at a lower layer part of the precipitation pool by an exclusive radioactivity treatment facility, and can emit the washing water having a safe reference value and having specific gravity lighter in weight than those of radioactivity materials, soil, stone, or the like remaining in an upper layer part at temperature (28°C or below) smaller than a boiling point and lower than a melting point temperature, and is naturally emitted into the air.;COPYRIGHT: (C)2013,JPO&INPIT
