Eco-resource slag effective utilization system

An eco-resource slag effective utilization system for neutralizing a harmful-dioxin-containing waste incineration ash slag that has not been processed into a molten slag, thereby allowing the same to be used as an eco-resource filter medium, the eco-resource slag effective utilization system comprising:

• a first step of kneading predetermined proportions of a harmful-dioxin-containing slag that has not been processed into a molten slag, which is selected from waste incineration ash slags generated during the burning of general wastes in a combustible waste incineration plant, a porcelain clay for ceramics, and a mineral clay for ceramics, such as a quartz powder or an alumina powder, thereby forming a clay material with a suitable size;
• a second step of burning the clay material in a burning oven for ceramics or wastes at a predetermined temperature for a predetermined period of time so that a liquid glaze can sufficiently penetrate into the inner region of the clay material, thereby forming a biscuit clay material;
• a third step of applying, to the biscuit clay material formed in the second step, a liquid glaze produced by kneading a powder made from a crushed special natural stone with a glaze for ceramics in a predetermined ratio followed by aging;
• a fourth step of penetrating the liquid glaze sufficiently into the inner region of the biscuit clay material, thereby making a solid matter;
• a fifth step of subjecting the solid matter impregnated with the liquid glaze to high-temperature burning in a burning oven for ceramics or wastes at a predetermined temperature for a predetermined period of time, so that a harmful component contained in the harmful-dioxin-containing slag is melted and enclosed in a vitreous material, thereby forming a vitreous filter medium made of a vitreous solid matter capable of purifying and restoring contaminated or polluted water;
• and
• a sixth step of installing the filter medium formed in the fifth step underwater in a contaminated water area to purify water and revive normal water.

An eco-resource slag effective utilization system for neutralizing a harmful-component-containing unprocessed sludge slag to allow the same to be used as an eco—resource filter medium, the eco-resource slag effective utilization system comprising:

• a first step kneading predetermined proportions of a harmful component—containing sludge slag that has not been processed into a sludge molten slag, which is selected from sewage sludge slags generated during the production of sewage sludge in a sewage treatment plant, a porcelain clay for ceramics, and a mineral clay for ceramics, such as a quartz powder or an alumina powder, thereby forming a clay material with a suitable size;
• a second step of burning the clay material in a burning oven for ceramics or melting at a predetermined temperature for a predetermined period of time so that a liquid glaze can sufficiently penetrate into the inner region of the clay material, thereby forming a biscuit clay material;
• a third step of applying, to the biscuit clay material formed in the second step, a liquid glaze produced by kneading a powder made from a crushed special natural stone with a glaze for ceramics in a predetermined ratio followed by aging;
• a fourth step of penetrating the liquid glaze sufficiently into the inner region of the biscuit clay material, thereby making a solid matter;
• a fifth step of subjecting the solid matter impregnated with the liquid glaze to high-temperature burning in a burning oven for ceramics or melting again at a predetermined temperature for a predetermined period of time, so that a harmful component contained in the sludge slag is melted and enclosed in a vitreous material, thereby forming a vitreous filter medium made of a vitreous solid matter capable of purifying and restoring contaminated or polluted water;
• and
• a sixth step of installing the filter medium formed in the above step underwater in a contaminated water area to purify contaminated water or the like and revive normal water.
