摘要：NOVELTY - Removal of chlorinated hydrocarbons in underground water using slow release type persulfate oxidant comprises mixing uniformly sulfate, sodium hydroxide, cement, sand and water, curing and shaping in mold into cylindrical alkaline slow release type persulfate oxidant, mixing oxidant with underground water, carrying out alkali activation and degrading chlorinated hydrocarbon contaminants in underground water. USE - Method for removing chlorinated hydrocarbons in underground water using slow release type persulfate oxidant (claimed) used for restoring heavy saline land. ADVANTAGE - The method improves transmission ability and utilization efficiency. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the preparation of slow release type oxidant comprises taking sodium hydroxide, dissolving in water, stirring, cooling to room temperature; mixing sulfate, cement, sand and water, adding sodium hydroxide solution, mixing uniformly; and filling in molds, standing at 20 plus minus 1 degrees C for 7 days, and taking out from mold.
