Research on Treating Acid Wastewater Containing Heavy Metals by Sulfate-Reducing Bacteria

摘要

Biological treatment with sulfate-reducing bacteria (SRB) has been considered as the most attractive alternative for heavy-metals-containing effluents decontamination. Ordinarily, these wastewaters contain high concentrations of sulfate and heavy metals, it is extremely essential for the development of a bioremediation technology to prevent its harm. Mechanism of SRB for wastewater treatment had been introduced in the paper, together with the application of treating wastewater containing several typical heavy metals. At last, current problems in engineering application of SRB are explained in the paper.
