    摘要: A method for treatment of halogen-containng waste material, in particular PVC-containing waste material, is disclosed, wherein the waste material in a decomposition step is heated in a reaction zone in a substantially closed system essentially without addition of water to a temperature between 150 and 750° C, preferably 250 - 350 C°, in the presence of a halogen-reactive compound selected from alkali and alkaline earth metal hydroxides, alkali and alkaline earth metal carbonates and mixtures thereof, so as to establish a controllable autogeneous pressure substantially above atmospheric pressure, in a sufficient reaction time to convert essentially all halogen present in the waste material to alkali or alkaline earth metal halides, said closed system preferably also comprising a condensation zone, where water vapour and volatile compounds liberated from the waste material are condensed. The remanence obtained in the decomposition step is washed with an aqueous solvent, preferably pure water, and the soluble and insoluble parts of the remanence are separated. By this method the halogen is removed from the waste without uncontrolled emission of halogen-containing acids to the environment.

    摘要: Disclosed herein are a solid waste treatment agent comprising phosphorous acid or a derivative thereof and/or hypophosphorous acid or a derivative thereof, or phosphorous acid or a derivative thereof and/or hypophosphorous acid or a derivative thereof, and an aluminum compound and/or a titanium compound, and a method of treating solid waste, which comprises adding the solid waste treatment agent to solid waste containing harmful metals and/or organic chlorinated compounds such as dioxins and PCB to make the solid waste harmless. When the solid waste treatment agent comprising phosphorous acid or a derivative thereof and/or hypophosphorous acid or a derivative thereof, and titanium oxide, or comprising phosphorous acid or a derivative thereof and/or hypophosphorous acid or a derivative thereof, titanium oxide and an aluminum compound is used as a solid waste treatment agent to treat solid waste under irradiation of rays, the solid waste can be effectively made harmless even when the treatment is conducted at a relatively low temperature.
