Removal of municipal wastewater effluent toxicity and formation of transformation products of trace organic contaminants after electrochemical oxidation treatment

沃茨中存在大量有机污染物，因此需要越来越有效的技术 ** 来避免污染地表水和沿海沃茨。在过去的20年里，废水中存在的痕量有机污染物（TOC），如药品和个人护理产品，刺激了对新的废水处理工艺的研究，这些工艺能够降低城市污水中这些污染物的浓度。ECOTHOR-W技术由E2 Meetings开发，是一种很有前途的技术，用于从工业废水中去除各种污染物，如脂肪，油和油脂，微量金属，总悬浮固体，甚至大肠菌群。E2 Meetings希望探索其旗舰技术在 ** 城市废水处理中的应用，并希望测量城市废水中经常报告的 ** TOC转化产物的形成。此外，它还对经处理的废水 ** 对水生生物的毒性感兴趣。在这里，我们提出了一个为期6个月的项目，与E2 Meetings密切合作，** 通过测量转换产品的 ** 形成和测量处理后废水的整体出水毒性，确定城市废水电化学处理的最佳参数。通过这种方式，ECOTHOR-W技术将不会产生不需要的转化产物，并且在使用最少能源的情况下大大降低废水的毒性。我们将采取一项双重战略，使我们能够在适当时候实现这一目标：1）使用基于液相色谱和 ** 高分辨率质谱的方法测量 ** 经常报告的痕量有机污染物的主要转化产物的形成2）比较电化学处理和未处理的毒性 ** 使用我的小组最近开发的一种敏感的测定方法，使用水蚤（D。magna）作为 ** 试验微生物。该项目将优化ECOTHOR-W技术，这将改善 ** 城市污水的质量，减少其对环境的负面影响。此外，我们的工作将使 ** E2 Meetings有机会扩展到市政污水处理厂市场，并在加拿大创造新的就业机会。

The presence of a multitude of organic contaminants in wastewaters requires increasingly efficient technologies**to avoid contamination of surface and coastal waters. In the last 20 years, the presence of trace organic**contaminants (TOCs) such as pharmaceuticals and personal care products in wastewaters has stimulated**research for new wastewater treatment processes able to reduce the concentration of those contaminants in**municipal sewage. The ECOTHOR-W technology, developed by E2Metrix, is a promising technology for the**removal of diverse contaminants from industrial wastewaters such as of fats, oils and grease, trace metals, total**suspended solids, and even coliforms. E2Metrix wishes to explore the application of its flagship technology to**the treatment of municipal wastewaters and desires to measure the formation of transformation products of**TOCs frequently reported in urban wastewaters. Also, it is interested in the toxicity of the treated effluents**towards aquatic organisms. Here we propose a 6-month project in close collaboration with E2Metrix to**determine optimal parameters for the electrochemical treatment of municipal wastewaters by measuring the**formation of transformation products and measuring the whole effluent toxicity of the treated wastewater. In**that way, the ECOTHOR-W technology will not produce of unwanted transformation products and the toxicity**of the effluent will be greatly reduced with minimal use of energy. We will adopt a two-fold strategy that will**allow us to attain that objective in due time: 1) Measure the formation of major transformation products of**frequently reported trace organic contaminants using a method based on liquid chromatography and**high-resolution mass spectrometry 2) Compare the toxicity of electrochemically treated and untreated**municipal effluents using a sensitive assay recently developed by my group that uses water fleas (D. magna) as**test organism. This project will optimize ECOTHOR-W technology, which will could ameliorate the quality of**municipal effluents and reduce their negative impact the environment. Additionally, our work will give**E2Metrix the opportunity to expand to the municipal wastewater plant market and create new jobs in Canada.
