Sulfolane, also known as 2,3,4,5-tetrahydrothiophene-1,1-dioxide or tetramethylenesulfone, is an organicsolvent, primarily used as an extraction solvent in the oil and gas processing industry. Sulfolane minimallyinteracts with soil organics and is quite miscible and therefore highly mobile when released in ground waters.This leads to its significant offsite migration. There have been reports of sulfolane contamination in ground andsurface waters around many gas processing sites.This project builds on our current research on degrading sulfolane using advanced oxidative as well asbiological means. Our findings have indicated that sulfolane in water can be treated by various combinations ofadvanced oxidative processes as well as by aerobic degradation. The proposal furthers the research andproposes to evaluate Delta Remediation Inc.'s Biologix® system to remediate sulfolane contaminated waters. Itwill also investigate the application of nano photocatalysis for the treatment of sulfolane contaminated waters.It is expected that the two (Biologix® and nano photocatalysis) will lead to a cost effective technology to treatsulfolane contaminated waters.

环丁砜，也称为2，3，4，5-四氢噻吩-1，1-二氧化物或四亚甲基砜，是一种有机溶剂，主要用作石油和天然气加工工业中的萃取溶剂。环丁砜与土壤有机物的相互作用极小，且极易混溶，因此在地下沃茨中释放时具有高度移动的性，这导致其显著的厂外迁移。在许多天然气加工厂周围的地下和地表沃茨中有环丁砜污染的报道，本项目建立在我们目前使用先进的氧化和生物方法降解环丁砜的研究基础上。我们的研究结果表明，环丁砜在水中可以处理的各种组合的先进的氧化过程，以及通过好氧降解。该建议进一步研究并建议评估三角洲修复公司。的Biologix®系统来修复环丁砜污染的沃茨。本论文还研究了纳米填料在处理环丁砜污染沃茨中的应用，预计这两种填料（Biologix®和纳米填料）将成为处理环丁砜污染沃茨的一种经济有效的技术。
