微生物技术治理水体重金属镉、铬污染的研究进展

Research progress of treatment of cadmium and chromium wastewater by microbiological technology

近年来,随着我国工农业迅速发展,"三废"的大量排放,水体中重金属污染愈发严重,其中重金属镉、铬的污染显得尤为突出。研究者利用微生物技术开展了大量治理污水中镉、铬的研究。本文就不同种类微生物对镉、铬的修复及作用机理进行论述,以期为微生物用于实际污水中镉、铬的治理提供参考。

In recent years,with the rapid development of China’s industry and agriculture,the large amount of"three wastes"has been discharged,and the pollution of heavy metals in water has become more serious.The heavy metal pollution,like cadmium and chromium,has become particularly prominent.Researchers have used microorganisms to carry out the treatment of cadmium and chromium in sewage.This article discusses the remediation mechanism of cadmium and chromium by different kinds of microorganisms,in order to provide the ability to fully achieve the application of bioremediation in practical cadmium and chromium wastewater.
