摘要
针对山西省山阴地区饮用井水中砷含量超标以及常规的活性氧化铝直接除砷效果不理想等问题,开发了一种新型复合除砷材料,基于沉淀法和化学物理法,分别采用单一化学制剂和混合化学制剂,对不同砷含量原水或井水进行除砷处理试验,并对该新型复合材料进行了配比及综合除砷效能分析.试验结果表明,平均除砷率能够达到90%以上;在PAM和FeCl3·6H2O的最佳投加量分别为50 mg/L和70 mg/L时,除砷率可达到93%;而新型复合除砷材料和活性氧化铝制剂混合除砷率可达到96.68%.
The arsenic in drinking well water exceeded the standard in Shanyin region in Shanxi that the average arsenic-removal ratio is better than 90% and the optimum dosages of PAM and FeCl3· 6H2O are 50 mg/L and 70 mg/L respectively, 93% of arsenic can be removed, furthermore, the arsenicremoval ratio of mixture of new composite materials for removing arsenic and activated alumina is up to 96.68%.
