Integration of biotechnology with nanotechnology to remediate sulfolane contaminated waters

亚砜，也被称为2,3,4,5-四氢噻吩-1,1-二氧化或四亚甲基砜，是一种有机溶剂，主要用作石油和天然气加工工业的萃取溶剂。亚砜与土壤有机物的相互作用很小，而且很容易混溶，因此在地下水中释放时流动性很强。这导致了它显著的异地迁移。有报道称，在许多天然气处理场所周围的地下水和地表水中存在环己烷污染。该项目建立在我们目前使用先进的氧化和生物手段降解亚砜的研究基础上。我们的研究结果表明，水中的亚砜可以通过高级氧化过程和有氧降解的各种组合来处理。该提案进一步研究，并建议评估Delta补救公司的Biologix®系统修复环砜污染的水。研究了纳米光催化在处理环砜污染水体中的应用。预计这两种技术（Biologix®和纳米光催化）将导致一种经济有效的技术来处理环砜污染的水。

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.
