腐殖质和典型矿物强化微生物呼吸去除污染物的研究进展
Advances in enhanced pollutants removal by microbial respiration with humus and typical minerals
【摘要】 环境污染微生物修复相比于物理化学修复方法,具有对环境扰动小、成本低等优点。多数情况下,由于污染环境中土著功能微生物的活性或数量较低,所以需要额外添加电子供体或电子受体来强化功能微生物的呼吸活性,但过量的添加势必会导致环境的二次污染。因此,寻找新的可以作为生物电子供体或电子受体而又对环境影响小的材料至关重要。腐殖质和矿物是自然界中生物地球化学循环的重要组成部分,影响着多种污染物在自然界中的迁移转化,同时也能够作为电子供体或电子受体参与微生物的呼吸作用进而强化污染物的去除。基于对国内外相关研究成果的归纳整理,本文综述和探讨了腐殖质、硫铁矿、锰矿石和磁铁矿等在微生物呼吸去除污染物中的研究情况,同时对未来的研究方向进行了总结和展望,为环境污染绿色修复提供新的思路。
【Abstract】 Compared with physical and chemical remediation methods, bioremediation of environmental pollution has the advantages of little disturbance to the environment and low cost. In most cases, due to the low activity and numbers of indigenous functional microorganisms in the polluted environment, additional electron donors or acceptors are required to strengthen the respiration activity of functional microorganisms, but excessive addition will cause secondary pollution of the environment. Therefore, it is very important to find new materials that can be used as bio-electron donors and electron acceptors with little impact on the environment. Humus and minerals are important parts of the biogeochemical cycle in nature, which impacts the migration and transformation of various pollutants in nature. At the same time, they have also been reported to participate in the respiration of microorganisms as electron donors or acceptors. Based on the summary of relevant research results at home and abroad, this article reviewed and discussed the application of humus, sulfur minerals, manganese minerals and iron minerals in pollutants removal by microbial respiration and the latest research progress. The future research directions were also summarized and prospected. This review can provide new ideas for green remediation of environmental pollution.
