重金属污染土壤微生物修复技术研究进展

Research progress on microbial remediation technology for heavy metal contaminated soil

对重金属污染土壤微生物修复问题进行了综述。第一个论题为微生物修复技术的影响因素,包括微生物种类;重金属浓度;外界因素:温度,pH,盐浓度。第二个论题为微生物修复技术机理,包括生物吸附、富集,生物转化,生物溶解、沉淀。在结尾就微生物修复技术发展前景进行了展望,以期为我国受重金属污染土壤的治理借鉴经验。

Based on papers published at home and abroad in recent years.Microbial remediation of heavy metal contaminated soil is reviewed.The first topic is the influencing factors of microbial remediation technologies,including:the type of host microorganisms;Concentration of heavy metals;External factors:temperature,pH,salt concentration.The second topic is the mechanism of microbial remediation technology,including biological adsorption,enrichment,biological transformation,biological dissolution and precipitation.At the end of this paper,the prospect of microbial remediation technology was prospected,hoping to be a reference for the treatment of heavy metal contaminated soil in China.
