Advanced wastewater treatment

加拿大人对保护地表水和地下水的质量以供当前和未来的有益用途极为感兴趣。污水处理技术的进步是确保水质持续改善的主要手段之一。本应用程序提出了对市政和制浆造纸废水进行改进处理的研究。一个研究项目旨在开发简单的技术来监测生物废水处理厂生物质的组成，以便工厂的设计者和操作员能够对处理厂的效率进行最佳控制。第二个项目旨在去除纸浆和造纸废水中可能存在的潜在内分泌干扰化合物（EDCs）。这种类型的EDCs值得关注，因为它们与在某些纸浆厂废水接收水域中栖息的鱼类的异常现象有关。第三个项目将设法提高对涉及膜生物反应器的废水处理新方法的影响的认识，加拿大在这项技术方面处于世界领先地位。最后，将研究一种有趣的方法来去除纸浆和造纸厂废水的颜色。结合电凝和臭氧化的初步实验表明，这种结合的方法可以成功地将废水处理与能量回收结合起来。

Canadians are vitally interested in protecting the quality of surface and groundwater for current and future beneficial uses.  Advances in wastewater treatment technology are one of the primary means of ensuring continued improvement in water quality.  This application proposes research to achieve improved wastewater treatment for municipal and pulp and paper mill wastewaters.  One research project is intended to develop simple techniques for monitoring the composition of biological wastewater treatment plant biomass, so that plant designers and operators can exert optimal control of treatment plant efficiency.  A second project is directed at the removal of potential endocrine-disrupting compounds (EDCs) that may be present in pulp and paper effluent.   EDCs of this type are of concern because they have been linked to observations of abnormalities in fish that inhabit receiving waters for some pulp mill effluents.  A third project will seek to develop an improved understanding of the impacts of a new approach to wastewater treatment involving membrane bioreactors - a technology in which Canada leads the world.  Finally, an interesting approach to colour removal from pulp and paper mill effluents will be investigated.  Preliminary experiments with a combination of electrocoagulation and ozonation have suggested that this combined approach may successfully couple wastewater treatment to energy recovery.
