| 中文摘要: |
| 水生态系统中沉积物是各类污染物质的汇集库，在外源污染陆续得到有效控制的基础上，亟需对内源污染特别是沉积物污染进行有效去除。在沉积物修复方法中，微生物促生剂技术由于具有安全环保、持续时间长、成本低等优点而受到重视。阐述了微生物促生剂的概念及其修复沉积物的作用机理，主要是通过增加沉积物中环境污染物的生物利用性使其可被生物降解，调整土著微生物的群落组成使其向有利于降解污染物的方向发展。并归纳了微生物促生剂的应用现状，除直接投加微生物促生剂外，还包括微生物促生剂配方研制、微生物促生剂缓释技术研发、微生物促生剂与其他方法的联合使用等，梳理了微生物促生剂应用优势和存在的问题，对微生物促生剂在沉积物修复领域的发展趋势进行了展望。 |
| 英文摘要: |
| The sediment in aquatic ecosystems acts as a sink for many organic pollutants with low water solubility. To effectively control pollution, the internal pollutants, particularly those in sediment, must be removed. Among the methods for cleaning up sediments, bio-stimulants are often selected due to the advantages of safety, effectiveness, long duration, and low cost. Bio-stimulants act by increasing the bioavailability of sediment pollutants. The increase in biodegradable pollutant availability leads to succession of the microbiome causing changes in community composition that enhance pollutant degradation. Different bio-stimulant formulations and application methods were also studied and compared, including direct injection, sustained release formulations and the use of bio-stimulants combined with other technologies. The advantages and disadvantages of bio-stimulation were analyzed and, finally, we speculate on the prospects of using bio-stimulants for sediment remediation. |
