摘要：NOVELTY - A bottom mud phosphorus release inhibitor comprises (mass%) metal peroxide (50-80), stearic acid (1-10), polyethylene glycol 4000 (1-10), and 40-200% mesh of weighing material (15-30). The metal peroxide is calcium peroxide and/or magnesium peroxide. The weighing material is quartz sand and/or cement. USE - Bottom mud phosphorus release inhibitor. ADVANTAGE - The phosphorus release inhibitor is prepared in anhydrous environment, thus avoiding the waste of effective oxygen peroxide, water and sediment. It can effectively increase the stability of water content so as to inhibit release of sediment phosphorus, and can be adjusted to proportion for different several days to several years of releasing period according to pollution. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of bottom mud phosphorus release inhibitor comprising mixing stearic acid and polyethylene glycol 4000 with absolute ethyl alcohol or carbon tetrachloride as organic solvent at 40-70 degrees C water bath, adding metal peroxide and weighting material, fully stirring to spherical, strip-shaped or tablet shape, mold drying to obtain spherical, strip-shaped or tablet shaped substrate sludge phosphorus releasing inhibitor, and recovering the organic solvent at 0.5-3 g/mL.
