项目摘要

0003928McCartyThis award supports Professor Perry L. McCarty, Director of the Western Region Hazardous Substance Research Center, Stanford University, to conduct collaborative research with Dr. Jaeho Bae, Department of Environmental Engineering, Inha University, Korea. The joint study will investigate the process of biological degradation of chlorinated ethenes. Principal objectives of the project include development of a numerical model that integrates the many factors involved in the reductive dechlorination of chlorinated ethenes, and to verify the model using field data. Because of their wide use in industry, chlorinated ethenes have become major contaminants of groundwater and soil. Remediation of groundwater contaminated with chlorinated ethenes is very difficult because they are dense, only partially soluble in water, and relatively resistant to chemical and biological degradation. Nevertheless, biological reductive dechlorination is one of the promising methods for bioremediation of contaminated sites, as it may be cost-effective compared to chemical and physical treatment, and it is also environmentally friendly as contaminants are degraded into non-toxic ethene. The multiple processes involved in reductive dechlorination are highly complex, and our knowledge of this process is still rather limited. This project will combine the complementary expertise and facilities of the American and Korean laboratories to advance our mutual understanding of the process.

0003928 McCartythis Award支持斯坦福大学西部地区危险物质研究中心主任Perry L. McCarty教授，与韩国Inha大学环境工程系Jaeho Bae博士进行合作研究。联合研究将研究氯化乙烯的生物降解过程。该项目的主要目标包括开发一个数值模型，该模型整合了氯化乙烯降低氯化的许多因素，并使用现场数据验证该模型。由于它们在工业中的广泛使用，氯化乙烯已成为地下水和土壤的主要污染物。用氯化乙烯污染的地下水的修复非常困难，因为它们是密集的，仅部分溶于水，并且对化学和生物学降解相对抗药性。然而，生物还原性脱氯是对受污染部位进行生物修复的有前途的方法之一，因为与化学和物理治疗相比，它可能具有成本效益，并且由于污染物被降解为无毒的乙烯，因此它也对环境友好。还涉及还原性脱氯的多个过程非常复杂，我们对这一过程的了解仍然相当有限。该项目将结合美国和韩国实验室的补充专业知识和设施，以提高我们对这一过程的相互了解。
