AMALGAMATED TREATMENT OF EXHAUST GAS PURIFYING AGENT BY PROMPTLY DEHYDRATED CAKE AND PROMPTLY THICKENED CAKE

PROBLEM TO BE SOLVED: To simultaneously and effectively treat the harmful materials between two poles by dividing the cake promptly dehydrated in a ready mixed concrete plants to a solid of a specific moisture content and sludge, forming the solid to granular cake as a purifying agent for the waste gases of the incineration furnace of a waste incineration plant, mixing the sludge with the flying ashes generated in the waste incineration plants and solidifying the mixture. SOLUTION: The place exclusive of the incineration plants is provided with an amalgamated treatment plant. The cake of the ready mixed concrete plants at plural points is carried thereto where the uniform granular cake having about 25% moisture content is formed. The cake is transported to the water incineration plants and is used as the purifying agent. The flying ashes generated in the incineration plants are recovered and are brought to the amalgamated treatment plant where the flying ashes are mixed with the activated sludge having the moisture content of about 60% and the mixture is solidified for the purpose of preventing the elution of the harmful materials. The diversion of ready mixed concrete facilities as the amalgamated treatment facilities is mostly possible as well in the areas where the ready mixed concrete plants are excess and, therefore, the one plant in the group may be switched to the amalgamated treatment plant. In addition, the groups of the ready mixed concrete plants may be categorized to a larger group in a wider range with the plural waste incineration plants as objects for selection.
