摘    要:简要介绍了国内近年来以化学沉淀法处理高浓度砷工业废水的试验研究及工业应用状况,讨论了化学沉淀法除砷工艺中的关键性工序,指出所得含砷沉淀物组成复杂(含砷、铁和钙离子等)及稳定性不够理想.为了适应目前环境保护的严格要求以及尽可能对废物进行资源化处理,认为对于砷和重金属浓度高、规模大的废水,应重视综合治理回收工艺研究.

关 键 词:  工业废水  化学沉淀法  处理

Abstract:The experimental investigations and industrial applications on treatment of high-arsenic concentration industrial effluents by chemical precipitation methods are brief introduced.The key process for removal arsenic by chemical precipitation are discussed.The sediment is complex and unstable because of containing arsenic,iron and calcium ion.For adapting to stringent requirement of environmental protection and waste treatment and resource recycling,It suggested that the research on comprehensive treatment pr...
Keywords:arsenic  industrial effluent  chemical precipitation  treatment
