摘　　要：在低碳氮比废水的处理过程中,碳源量成为影响总氮去除效率的主要制约因素。外加碳源是一种常见的提高总氮去除效率的手段,综述了制取缓释碳源的主要材料、合成方法,并指出了缓释碳源材料在实际应用中所存在的问题和今后的研究方向,总结了碳源材料的选择、制备在实际工程应用中的重要性。During the process of low carbon-nitrogen ratio sewage treatment, the amount of carbon source was the main limiting factor affecting the removal efficiency of total nitrogen. Adding carbon source is a common method to improve the removal efficiency of total nitrogen. The main materials and synthetic method of slow-release carbon source were summarized;besides, the existing problems of this kind of material in practical application as well as its future research direction were pointed out. Finally, the significance of carbon source material selection and preparation in actual project was summarized.
