Characterization of optimal running parameters for the inactivation of enteric bacteria by electrocoagulation in a novel wastewater treatment unit

在偏远地区或缺乏安全管理废物的必要基础设施的地区，废水处理是一项重大挑战。化学处理或通过运输去除废水的费用可能高得令人望而却步。在这样的地区，废物经常被简单地留在未经处理或倾倒在露天矿坑中。如果选择不当，这些垃圾场会对地下水造成污染。粪便微生物，特别是细菌，是令人担忧的主要污染物，因为它们很容易迁移到地下水中。食用粪便细菌是一种健康风险，因为它可能导致轻微到严重的疾病，甚至致命的疾病。解决远程或紧急废水处理问题的一种方法是使用可在现场部署的移动处理装置。为了显著清除或销毁人类排泄物中发现的大量粪便微生物，斯威夫特环境设备有限公司设计了一种基于电凝聚技术的移动式废水处理装置。电凝聚在废水处理中的成功应用已经有了很长的历史。斯威夫特环境设备公司引入了新颖的专有设计元素，使该系统可以携带，同时仍可处理大量废水。Ania Ulrich博士(艾伯塔大学)与SWIFT环境设备有限公司建立了合作伙伴关系，以评估该废水处理装置灭活粪便细菌的能力。这项合作的目标是在模型系统中确定灭活粪便细菌的最佳电凝聚参数，并将其与实际废水条件下装置的性能进行比较。成功确定最佳工艺参数将使SWIFT Environmental Equipment Ltd.能够构建失活动力学数据库，用于优化便携式设备的废水处理性能并对其进行故障排除。

Treatment of wastewater is a significant challenge in remote areas, or those that lack the necessary infrastructure to safely manage waste. Chemical treatment or removal of wastewater by transport can be prohibitively expensive. In such areas, waste is often simply left untreated or dumped into open pits. These dump sites, if incorrectly chosen, pose a risk to groundwater contamination. Fecal microorganisms, specifically bacteria, are the primary contaminant of concern as they can easily migrate into groundwater. Consumption of fecal bacteria is a health risk as it can cause mild to severe, and even fatal, illness. A solution to the problem of remote, or emergency, wastewater treatment is to use a mobile treatment unit that can be deployed on-site. To significantly remove or destroy the large numbers of fecal microorganisms found in human waste, Swift Environmental Equipment Ltd. has designed a mobile wastewater treatment unit based on electrocoagulation technology. Electrocoagulation has a demonstrated history of successful use in wastewater treatment. Swift Environmental Equipment has introduced novel proprietary design elements that allow this system to be portable, yet still treat substantial volumes of wastewater. Dr. Ania Ulrich (University of Alberta) has established a partnership with Swift Environmental Equipment Ltd. to assess the ability of this wastewater treatment unit to inactivate fecal bacteria. The objectives of this collaboration are to determine the optimal electrocoagulation parameters for inactivation of fecal bacteria in a model system, and to compare this to the performance of the unit when actual wastewater conditions are applied. Successful identification of optimal processing parameters will allow Swift Environmental Equipment Ltd. to construct a database of inactivation kinetics, which will be used to optimize and troubleshoot wastewater treatment performance of the portable unit.
