Zusammenfassung:	PURPOSE:To provide a water pollution preventing agent for absorbing alkali calcium eluted into water because of hydraulic materials such as cement, lime, a solidifying material containing cement or lime, concrete and mortar used at the time of solidifying mud or constructing an artificial pond or a waterway. CONSTITUTION:A water quality turbidity preventing agent contains calcium oxide, calcium sulfate, aluminum oxide and silicon dioxide cured materials, and is prepared by mixing one or more of slaked lime, quick lime, gypsum and volcanic ash with coal ash or 1 used coal waste gas treatment agent and hydrated curing, and then treating by means of smoke containing sulfur oxide and nitrogen oxide. The water pollution preventing agent is prepared by utilizing a used smoke treatment agent of lime family, and the elusion of alkali calcium and the rise of pH can be reduced and controlled easily and effectively by the agent. As the pollution preventing agent itself is cured in water to form a solidified body, neither outflow from the water nor scattering in the water is generated, and secondary pollution is also prevented.
