摘要:

重金属废水的排放带来了长期的环境污染。利用硫酸盐还原菌生物还原硫酸盐的过程中同时可将重金属化学沉淀为难溶金属硫化物而去除。文章对硫酸盐生物还原法去除重金属的原理、特点、影响因素和研究现状进行了阐述,从而说明该法去除重金属是可行和有效的,它对于处理重金属废水具有现实意义。

关键词: 重金属, 硫酸盐还原菌, 生物还原, 硫酸盐

Abstract:

The Disposal of wastewater containing heavy metals brings out long-term environmental pollution.Biological reduction of sulfate with sulfate-reducing bacteria(SRB) can chemically precipitate heavy metals and remove the insoluble metal sulfide at the same time.The principle,characteristics,influential factors and current research of heavy metals removal with biological reduction of sulfate are described in this paper.It is feasible and effective to removal heavy metals with biological method and it has reliable significance for the treatment of heavy metals wastewater.

Key words: heavy metal, sulfate-reducing bacteria(SRB), biological reduction, sulfate
