Development of a Trickle Filter for Treating Sour Water from Oil Shale Processing Plants

处理油页岩加工厂含硫废水的滴滤器研制从油页岩中提取石油是通过热解预干燥的粉碎页岩来实现的。尽管干燥，页岩仍保持约5%的残余水分，最终以水相形式存在于热解过程的凝析液流中。这种被称为酸性水的水相含有一系列有机化合物，包括羧酸、氮杂环化合物和酮。这项提议的目的是开发滴滤器来处理含酸水。在滴滤池中生长的生物膜是支持生长缓慢的微生物物种的理想选择。需要研究将油页岩沉积物中的本地微生物转移到将用于过滤器的耐用砾石中。

Development of a Trickle Filter for Treating Sour Water from Oil Shale Processing Plants. Oil is extracted from oil shale by pyrolysing pre-dried crushed shale. Despite drying , the shale retains a residual moisture level of approximately 5% which ultimately ends up as an aqueous phase in the condensate stream from the pyrolysis process. This aqueous phase, know as sour water, contains a range of organic compounds, including carboxylic acids, nitorgen heterocyclics and ketones. This aim of this proposal is to develop trickle filters to treat the sour water. The biofilms that develop in trickle filters are ideal for supporting slow growing microbial species. Research is needed to transfer native microorganisms in the oil shale desposit to the durable gravels that will be used in the filter.
