摘要
介绍了硫化物沉淀法在重金属离子废水处理中的研究现状,合成了一种新型硫化物重金属捕集剂(以下简称SPHM),运用SPHM,通过絮凝、沉淀、过滤处理,对水溶液中的铜离子一次捕集率可达99.56%,与传统的氢氧化物沉淀法相比,沉淀pH值更低、更易过滤、Cu2+捕集效果更好。
The present situation of the method of sulfide precipitation for the treatment of water polluted with heavy metal ions was introduced. A sulfide (SPHM) for the treatment was prepared. Using SPHM, followed flocculantion, precipitation and filtration, 99.6% of the copper ions in the aqueous were removed. Compared with the classic method, it needed lower pH for precipitation, brought easily filtration and a better result in the treatment.
