Preparation and application of superfine suspended calcium hydroxide
The invention relates to preparation and application of superfine suspended calcium hydroxide. The superfine suspended calcium hydroxide product is prepared by reacting quick lime with water, deslagging and grinding. The prepared superfine suspended calcium hydroxide can be continuously kept stable, and the appearance of the superfine suspended calcium hydroxide is not obviously changed after the superfine suspended calcium hydroxide stands for 4 weeks. The treatment effect of the superfine suspended calcium hydroxide is superior to the indexes (total phosphorus, chromium, nickel, fluoride and the like) of similar products sold in the market, so that the use amount of medicaments is saved, and the treatment cost of the acid wastewater is reduced.
本发明涉及一种超细悬浮氢氧化钙的制备及其应用，该超细悬浮氢氧化钙产品通过生石灰与水反应，经除渣、研磨制备而成。本发明制备的超细悬浮氢氧化钙能够持续保持稳定，静置4周内外观无明显变化。处理酸性废水，本发明的超细悬浮氢氧化钙的处理效果，优于市售同类产品的指标（总磷、铬、镍、氟化物等），从而节省药剂的使用量，降低酸性废水的处理成本。
