摘要
稻田重金属Cd的污染严重影响粮食品质和人类健康.微生物治理Cd污染是采用生物法治理Cd污染的重要部分,受到研究人员的青睐.它具有生长周期短、治理效果好、操作简便、绿色环保等特点.该文系统地归纳了近年来Cd污染的现状,总结了不同种属微生物对Cd污染的修复作用,探讨了微生物修复Cd污染土壤的吸附、络合、矿化作用机制及影响因素,并提供了未来Cd污染治理的研究方向,试图为重金属Cd污染微生物治理的发展提供参考.
Paddy fields are polluted by heavy metal Cd,which seriously affects grain quality and human health.Cd pollution treated by microorganism is an important part of biological treatment for Cd pollution,with the advantage of short growth cycle,good treatment effect,simple operation,green and environmentally friendly,which is favored by scientists.The status of Cd pollution was summarized systematically in recent years,different microbes for Cd remediation were generalized,the mechanism of microbial remediation on Cd contaminated soil for adsorption,complexation,mineralization and influencing factors were discussed,and the future research direction of Cd pollution treatment were provided.We try to provide a reference for the development of Cd remediation by microbes.
