The present invention uses the waste heat generated during incineration of waste to generate a thermally active catalyst chemical reaction and dioxins, furans, polychlorinated biphenyls in waste incinerators to minimize the generation of harmful decomposition products with high temperature hydrogen gas obtained therefrom. It relates to a harmful substance removal system such as.;The present invention is a waste treatment system capable of removing hardly decomposable, carcinogenic and endocrine disrupting harmful substances such as dioxins, furans, polychlorinated biphenyls, SOx, NOx, etc. generated in waste incineration facilities and various industrial sites. By using high-temperature hydrogen gas generated by its pyrolysis as a fuel in the furnace, waste is thermally decomposed by high temperature pyrolysis to generate flammable gas so that waste volume can be minimized and recycled. And a device; The high temperature gas generated at this time is utilized as a heat source for maintaining the reaction of pyrolysis and gasification by the thermally active catalyst chemical reaction so that the hydrogen gas is produced by itself, and the hydrogen gas produced through the thermally active catalyst chemical reaction A combustion unit using hydrogen gas as a fuel provided to be used as a fuel; A hydraulic sprayer (25) for directly transferring the solid carbide of the remaining pyrolyzed waste to a molten part to be melted with hydrogen gas, and cooling and solidifying the slag (18) discharged from the incineration melting furnace; A wet dust removal device (16) consisting of a hydraulic sprayer (25) and a stepped sedimentation tank for spraying water into the exhaust gas discharged through a pyrolysis gasification and incineration melting furnace as a rear end facility; It is connected to the rear end of the wet dust removal device 16, the low-temperature plasma to ionize the gas by the reaction reaction with hydrogen gas to remove the harmful gas again, and the low-temperature plasma reactor, the exhaust gas is purified gas Incinerator, characterized in that to be made in a continuous process of removing harmful substances as a whole including a selective catalyst reduction reaction tower 20 and a stack 22 connected to the selective catalyst reduction reaction tower 20 in real time monitoring to Provide chemical waste hazardous removal system.;In addition, sedimentation wastewater from waste bunkers or other wastewater from incinerators is introduced into the incinerator's internal cooling water, thus eliminating the need for a separate water purification facility and providing a system that minimizes the discharge of harmful substances.
