The aim of this project is to better characterise the dissolved organic nitrogen (DON) in sewage treatment plant influent, determine its fate in biological nutrient removal (BNR) plants, and to evaluate and develop an appropriate treatment technology. As a result of tightening effluent N licence requirements for sewage treatment plants, the dissolved organic nitrogen (DON) fraction has become extremely important. In many cases, the DON forms the major fraction of the effluent N, and is constraining further reductions in licence specifications, and in some cases it is the cause of failure to meet licence. DON is refractory (un-biodegradable), very poorly characterised, its fate in conventional biological treatment processes not known, and its eventual impact on the environment unknown. Considering its importance, it is critical that these issues are addressed. This proposal intends to address some of them. This project is an APA(I) PhD student project.

本项目的目的是更好地监测污水处理厂进水中溶解性有机氮（DON），确定其在生物脱氮（BNR）厂中的去向，并评估和开发合适的处理技术。 由于污水处理厂的污水氮许可证要求越来越严格，溶解有机氮（DON）部分变得非常重要。在许多情况下，DON形成了流出物N的主要部分，并且限制了许可规格的进一步降低，并且在某些情况下，它是未能满足许可的原因。 DON是难降解的（不可生物降解的），特征非常差，其在常规生物处理过程中的命运未知，其对环境的最终影响未知。 考虑到其重要性，解决这些问题至关重要。 本提案旨在解决其中一些问题。 该项目是阿帕（I）博士生项目。
