项目摘要
High-strength wastewater (HSW) generated from different sources in oil and gas industries poses a great challenge for treatment in conventional wastewater treatment facilities. Elevated levels of suspended solids, dissolved solids, oils and grease, salinity are some common characteristic features of such HSW. Extraction of gas from unconventional natural gas resources requires the management of large amounts of wastewater that return to the surface, after gas extraction, as flowback or produced water. To limit the discharge of different contaminants to the environment, HSW must be subjected to increasingly intense treatment processes to achieve optimal discharge or reuse standards.**Application of electrocoagulation (EC) has the potential for pre-treatment of HSW due to its simple, reliable and cost-effectiveness. EC is associated with the anodic dissolution of a sacrificial metal electrode to generate in situ coagulants. The nascent metal ions are very efficient coagulants and quickly form large flocs, which in turn can physically adsorb suspended solids, colloidal particles and chemically adsorb pollutants from HSW. Membrane distillation (MD) is an emerging technology to produce fresh water by desalination or reusable water from pre-treated wastewater. MD, a thermally driven process, allows water vapor to pass through a membrane and unlike reverse osmosis is not pressure driven. MD operates at much lower temperatures compared to other thermal processes and potentially can use low-grade waste heat and solar or geothermal energy as an energy source. Integration of EC with MD can formulate a sustainable water recovery process for HSW in the oil and gas industries.**The outcomes of this project will significantly add value for the company, Kleinfelder Canada Inc., and Canada in general. In effect, this project aims to develop practical solutions for the recovery and reuse of HSW and reduce withdrawal of freshwaters from different sources. The proposed integrated EC-MD system is expected to recover large fraction of the wastewater for reuse.******
油气行业中不同来源产生的高强度废水对常规废水处理设施的处理提出了巨大挑战。悬浮固体、溶解固体、油和油脂、盐度的升高是此类高盐水的一些共同特征。从非常规天然气资源中开采天然气需要对大量废水进行管理,这些废水在天然气开采后作为返排水或采出水返回地面。为了限制不同污染物向环境的排放,高铁水必须经过越来越严格的处理过程,以达到最佳的排放或再利用标准。**电絮凝(EC)因其简单、可靠和成本效益高而具有预处理HSW的潜力。EC与牺牲金属电极的阳极溶解有关,以产生原位混凝剂。新生金属离子是非常有效的混凝剂,可以快速形成大絮凝体,从而物理吸附悬浮固体、胶体颗粒,化学吸附HSW中的污染物。膜蒸馏(MD)是一项新兴技术,通过将废水预处理后脱盐或再利用水生产淡水。MD是一种热驱动的过程,允许水蒸气通过膜,与反渗透不同,它不是压力驱动的。与其他热过程相比,MD的工作温度要低得多,并且可能使用低品位的废热和太阳能或地热能作为能源。将EC与MD相结合,可以为油气行业的HSW制定可持续的水回收工艺。**该项目的成果将显著增加公司、kleinfeld Canada Inc.和整个加拿大的价值。实际上,该项目旨在制定切实可行的解决方案,以回收和再利用HSW,并减少从不同来源提取淡水。拟议的综合EC-MD系统有望回收大部分废水进行再利用。******
