提高含铁废水中和渣中铁含量的方法
The Method of Increased Iron Content in the Precipitation from Neutralization of Waste Water
【摘要】 研究了一种循环中和-分段沉淀处理酸性含铁废水的方法,使用该方法可以提高氢氧化铁沉淀渣的总铁品位,降低碱用量。某工业废水经4次循环处理,总铁含量达61.1%,达到铁矿石冶炼的工业品位.
【Abstract】 The recycling process of treated the acid waste water by neutralization-graded precipitation was studied.Total iron content in the precipitation was increased and the alkali was decreased.Total iron content in the precipitation was raised to 61.1% by four times treating waste water and meet up to standard demanded.
