目前，为应对更加严格的氮磷排放标准，城市污水处理厂普遍通过向生物营养物去除工艺中投加外碳源以强化反硝化脱氮。本文采用生物营养物去除( BNR)的工艺，构建工艺参数对过程中水质影响的实验模型，同时组装试验装置，测得数据，对预测的结果予以试验反证，研究了多种碳源在不同初始COD和反应时间下的厌氧释磷和好氧吸磷的效果，以及几种新型碳源的前景分析，总结了几类节省碳源的工艺措施。

At present, in order to reply the more strict standard of nitrogen and phosphorus, to enhance denitrification, addition of extra carbon source to biological nutrient removal ( BNR) processes has become more common for municipal wastewater treatment plants. Based on the process model of a BNR system, the effects of operational parameters on the effluent quality were predicted by modeling, and were testified simultaneously by a lab-scale experiment, the effects of several types carbon sources in initial COD concentrations and HRT on anaerobic P-release and aerobic P-uptake were studied, different carbon sources future situation were analyzed, and the measures of saving carbon source were summarized.
