氯代有机物污染场地的监控自然衰减修复初探
Preliminary inquiry of monitored natural attenuation remediation of chlorinated organic compounds contaminated sites
摘要
Abstract
Due to the high toxicity, potential of biological accumulation, recalcitrance to degradation and the known carcinogenic/teratogenic/mutagenic effects, the chlorinated organic compounds have been listed as priority controlled pollutants by the United States Environmental Protection Agency (EPA). In view of chlorinated pollutants contaminated sites, the traditional physical, chemical and biological remediation methods often impose relatively high costs and considerable impacts on the surrounding environment. The monitored natural attenuation (MNA) is an effective technology for site remediation and management and has been widely used internationally, which gradually attracts more and more attentions in China in recent years. It relies on the intrinsic potential of the pollutants to degrade naturally to meet the remediation requirements, and thereby would reduce treatment costs and lower on-site project risks. This paper focuses on the introduction of MNA technology, as well as the characteristics of chlorinated organic compounds such as the biodegradation pathways and mechanisms during the process of natural attenuation, the main degradation microbial communities and the key biodegradation enzymes. A preliminary discussion on the suitability of implementing MNA remediation on chlorinated organic compounds contaminated sites is provided.关键词
