摘要

Abstract > The chlorinated volatile organic compounds (CVOCs), tetrachloroethene (PCE), trichloroethene (TCE), and 1,1,1‐trichloroethane (1,1,1‐TCA), often found as commingled contaminants of concern (COCs) in groundwater, can degrade via a variety of biotic and abiotic reductive pathways. In situ remediation of a groundwater contaminant source area containing commingled 1,1,1‐TCA, PCE, and TCE was conducted using a combined remedy/treatment train approach. The first step was to create geochemically reducing conditions in the source area to degrade the CVOCs to lesser chlorinated CVOCs (i.e., 1,1‐dichloroethane [1,1‐DCA], 1,1‐dichlorethene [1,1‐DCE], cis ‐1,2‐dichoroethene [ cis ‐1,2‐DCE], and vinyl chloride [VC]) via enhanced reductive dechlorination (ERD). Carbon substrates were injected to create microbial‐induced geochemically reducing conditions. An abiotic reductant (zero‐valent iron [ZVI]) was also used to further degrade the CVOCs, minimizing the generation of 1,1‐DCE and VC, and co‐precipitate temporarily mobilized metals. An in situ aerobic zone was created downgradient of the treatment zone through the injection of oxygen. Remaining CVOC degradation products and temporarily mobilized metals (e.g., iron and manganese) resulting from the geochemically reducing conditions were then allowed to migrate through the aerobic zone. Within the aerobic zone, the lesser chlorinated CVOCs were oxidized and the solubilized metals were precipitated out of solution. The injection of a combination of carbon substrates and ZVI into the groundwater system at the site studied herein resulted in the generation of a geochemically reducing subsurface treatment zone that has lasted for more than 4.5 years. Mass concentrations of total CVOCs were degraded within the treatment zone, with near complete transformation of chlorinated ethenes and a more than 90 percent reduction of CVOC mass concentrations. Production of VC and 1,1‐DCE has been minimized through the combined effects of abiotic and biological processes. CVOC concentrations have declined over time and temporarily mobilized metals are precipitating out of the dissolved phase. Precipitation of the dissolved metals was mitigated using the in situ oxygenation system, also resulting in a return to aerobic conditions in downgradient groundwater. Chloroethane (CA) is the dominant CVOC degradation product within the treatment zone and downgradient of the treatment zone, and it is expected to continue to aerobically degrade over time. CA did not accumulate within and near the aerobic oxygenation zone. The expectations for the remediation system are: (1) the concentrations of CVOCs (primarily in the form of CA) will continue to degrade; (2) total organic carbon concentrations will continue to decline to pre‐remediation levels; and, (3) the groundwater geochemistry will experience an overall trend of transitioning from reducing back to pre‐remediation mildly oxidizing conditions within and downgradient of the treatment zone. </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> <div class="translation abstracttxt"> <span

>氯化挥发性有机化合物（CVOC），四氯乙烯（PCE），三氯乙烯（TCE）和1,1,1-三氯乙烯（1,1,1-TCA）通常被发现为地下水中关注的污染物（COCs），可以降解通过各种生物和非生物还原途径。使用组合的补救/治疗列车方法进行含有混合的1,1,1-TCA，PCE和TCE的地下水污染源区的修复。第一步是在源区中产生地球化学还原条件，将CVOC降解到较少的氯化CVOC（即1,1-二氯乙烷[1,1-DCA]，1,1-二氯乙烯[1,1-DCE]，通过增强的还原脱氯（ERD）， CIS </ I> -1,2-二氯乙烯[ CIS </ I> -1,2-DCE]和氯乙烯[VC]）。注射碳基材以产生微生物诱导的地球化学降低条件。反生生物还原剂（零价铁[ZVI]）还用于进一步降解CVOC，最小化1,1-DCE和VC的产生，并共沉淀暂时动集的金属。通过注射氧气将处理区的降级为氧气区域的。剩余的CVOC降解产品和由地球化学降低条件引起的暂时动集的金属（例如，铁和锰）通过有氧区域迁移。在有氧区内，较少的氯化CVOC被氧化，溶解的金属沉淀出溶液。将碳基材和ZVI的组合注射到本文所研究的部位的地下水系统中产生的产生地球化学减少地下处理区的产生持续超过4.5年。总CVOC的质量浓度在处理区内降解，接近氯化替代的完全转化，CVOC质量浓度的降低超过90％。通过非生物学和生物过程的综合影响，vc和1,1-dce的生产最小化。 CVOC浓度随着时间的推移而下降，暂时动集的金属沉淀出溶解的相。使用溶解金属的沉淀利用于原位氧合体系来减轻溶解金属，也导致降级地下水中的恢复到有氧病症。氯乙烷（CA）是治疗区内的主要CVOC降解产物和治疗区的降级，预计会随着时间的推移继续提供有氧化。 CA没有积聚在有氧氧合区内和附近。对修复系统的期望是：（1）CVOC的浓度（主要是CA的形式）将继续降低; （2）总有机碳浓度将继续下降到预补丁水平; （3）地下水地球化学将经历从减少恢复到治疗区内的预补丁预补充温和氧化条件的整体趋势。 </ p> </ abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> </div> <div
