Phenol and its derivatives are major organic pollutants that are produced by various industrial activities and are present in landfill leachates. Exposure to most phenolic compounds pose a serious risk to human health and aquatic life, due to their toxic, mutagenic and carcinogenic effects. Therefore, phenolic compounds need to be eliminated from industrial effluents before being discharged into the environment. As phenols are also not easily biodegradable, treatment methods are limited. ****A new and innovative method for potential treatment of phenols is the electro-oxidation process. This process generates hydroxyl radicals which have the potential to degrade recalcitrant organics, conversely they may also reach bicarbonate ions, causing a reduction in the efficiency of the process. As this research has never been conducted the data from this applied research project will shed some much needed light on the treatment of phenols and the impact of the electro-oxidation process.****This applied research project will develop Xogen's advanced electrolysis oxidation technology for removal of phenols from landfill leachates in comparison to contaminant discharge limits. Xogen's technology uses unique electrodes making it unique from other electro-oxidation technologies on the market and increasing its potential to destroy contaminants in wastewater. This project will also determine the most optimal operating conditions in order to maximize the remove rate of toxic phenols from landfill leachates. The optimized technology will allow Xogen to efficiently treat problematic contaminants before being discharged into the environment. Xogen will use the results from this project to further their understanding of their technologies capabilities, identify key markets to enter and provide a much needed solution to a common problem faced by landfills in North America.**

苯酚及其衍生物是各种工业活动产生的主要有机污染物，存在于垃圾填埋场渗滤液中。接触大多数酚类化合物，由于其毒性、诱变和致癌作用，对人类健康和水生生物构成严重风险。因此，在排放到环境中之前，需要从工业废水中消除酚类化合物。由于酚类也不容易生物降解，因此处理方法有限。* 一个新的和创新的方法，潜在的处理酚是电氧化过程。该过程产生羟基自由基，其具有降解难降解有机物的潜力，相反，它们也可能到达碳酸氢根离子，导致该过程的效率降低。 由于这项研究从未进行过，因此这项应用研究项目的数据将为苯酚的处理和电氧化过程的影响提供一些急需的信息。该应用研究项目将开发Xogen的高级电解氧化技术，用于去除垃圾填埋场渗滤液中的酚类物质，并与污染物排放限值进行比较。Xogen的技术使用独特的电极，使其与市场上的其他电氧化技术不同，并增加了其破坏废水中污染物的潜力。 本项目还将确定最佳操作条件，以最大限度地提高垃圾填埋场渗滤液中有毒酚类的去除率。优化的技术将使Xogen能够在排放到环境中之前有效地处理有问题的污染物。Xogen将利用该项目的结果进一步了解其技术能力，确定进入的关键市场，并为北美垃圾填埋场面临的共同问题提供急需的解决方案。
