  • 摘要: 四氯乙烯(PCE)、三氯乙烯(TCE)等氯化溶剂常被看作地下水中的主要污染物质，针对该类典型污染物，厌氧脱氯渗透性反应墙的应用引起了较多关注。在渗透性反应墙中，微生物消耗地下水中的溶解氧，为后续生物厌氧脱氯提供高还原性环境。树皮填料水解后，同时为好氧微生物消氧气及降解氯化乙烯污染物提供电子，而好氧微生物电子消耗量远高于生物脱氯。研究解释了不同环境下松树皮对好养微生物脱氧作用的维持能力，得到松树皮的耗氧容量为31.2 mg·g-1，并证明了不同环境条件会改变反应墙对地下水脱氧反应的速率。
    Abstract: Chlorinated solvents, such as tetrachloroethene(PCE) and trichloroethene (TCE), are regarded as major contaminants in groundwater. Among diverse of remediation technologies treating chlorinated solvent that are developed, bioremediation via anaerobic reductive dechlorination with permeable reactive barrier (PRB) has received lots of attentions. Strong reduction environment will occur due to oxygen uptake by aerobic microbes in PRB, which is in favor of anaerobic dechlorination. When pine mulch was filled in PRB, and its hydrolysis happened consequently, then the produced electrons participated in both oxygen consumptions by aerobic microbes and dechlorination reactions, while aerobic microbes consume far more elections than dehalococcoides. This study explained the capacity of mulch (pine bark) to serve as electron donor to sustain aerobic microbes to remove oxygen from groundwater that flowing towards a barrier under different conditions, and oxygen consumption capacity was determined as 31.2 mg·g-1, and proved that different environmental conditions will impact reaction rates of groundwater deoxidization.
