This project aims to develop a novel technology to achieve mainstream nitrogen removal from domestic sewage via nitrite shunt. Nitrite shunt can reduce energy consumption and promote energy recovery compared with the conventional nitrogen removal process. However, it is difficult to inactivate nitrite-oxidising bacteria, which is a key barrier for achieving nitrite shunt. By advancing the underpinning science and introducing a novel technology that innovatively harnesses a human waste, the project expects to remove the barrier. Expected outcomes will support the transformation of sewage treatment plants into net-zero energy generators. This should provide economic, environmental and energy benefits for Australia’s water and energy sectors.

本项目旨在开发一种通过亚硝酸盐分流实现生活污水主流氮去除的新技术。与常规脱氮工艺相比，亚硝酸盐分流法可以降低能耗，促进能量回收。然而，亚硝酸盐氧化细菌很难灭活，这是实现亚硝酸盐分流的关键障碍。通过推进基础科学和引入一种创新地利用人类排泄物的新技术，该项目有望消除这一障碍。预期结果将支持将污水处理厂转变为净零能耗发电机。这将为澳大利亚的水和能源部门带来经济、环境和能源效益。
