Advanced wastewater treatment

加拿大人非常关心保护地表水和地下水的质量，以供当前和未来的有益用途。 废水处理技术的进步是确保水质持续改善的主要手段之一。 本申请提出了研究，以实现城市和纸浆和造纸厂废水的改进的废水处理。 一个研究项目旨在开发简单的技术，用于监测生物废水处理厂生物量的组成，以便工厂设计人员和操作人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内分泌干扰化合物。 这种类型的内分泌干扰物是令人关注的，因为它们与观察到的鱼类异常有关，这些鱼类栖息在接受某些纸浆厂废水的沃茨。 第三个项目将寻求更好地了解一种涉及膜生物反应器的废水处理新方法的影响，加拿大在这方面处于世界领先地位。 最后，一个有趣的方法，从纸浆和造纸厂废水的颜色去除将进行调查。 电凝聚和臭氧化相结合的初步实验表明，这种结合的方法可以成功地耦合废水处理的能量回收。

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.
