生活污水深度处理再生利用具备经济和生态双重价值。但我国热带地区生活污水因碳源过低，深度脱氮成为制约中水达标及回用的技术瓶颈。本研究面向热区低碳源生活污水中氮的深度去除，利用可规模化处理污水的好氧颗粒污泥-膜生物反应器耦合工艺体系，研究改良污泥活性炭促发颗粒污泥造粒反应的可控化调节，典型污染物的特异性吸附及生化转化，膜催化诱导及膜污染控制等各功能过程的影响因子，以揭示污泥活性炭及膜材料在微纳界面上的定向构筑、修饰对污染物聚集、污泥造粒、催化膜诱导等水质协同净化过程的影响规律，旨在为低碳源生活污水中氮的高效脱除提供新的技术途径，为实现热区中水安全回用提供基础资料和科学依据。

The recycling of domestic sewage has economic and ecological values. However, the low carbon source and high nitrogen in the domestic sewage of tropical zones have become the bottleneck to restrict the standard and reuse of the water. The research aiming at the deep removal of nitrogen from domestic sewage with low carbon source in tropical zones, with utilizing the coupled process system of aerobic granular sludge and membrane bioreactor on a large scale. The influencing factors of such functional processes as controlled regulation of granulation reaction, specific adsorption and biochemical transformation of typical pollutants, membrane catalytic induction and membrane fouling control by improved activated sludge activated carbon will be studied. In order to reveal the influence of the directional construction and modification of activated sludge and membrane materials on the process of water quality co-purification, eg. pollutant aggregation, sludge granulation and catalytic membrane induction. The aim of this study is to provide a new technical approach for the efficient removal of nitrogen from domestic sewage with low carbon sources, as well as to provide the basic information and scientific basis for the safe reuse of water in tropical zones.
