摘　　要：生活污水低碳化趋势导致了生物脱氮技术的低效率。固体碳源在用作载体的同时可以提供电子供体,强化生活污水的脱氮过程。目前对于固体碳源的应用进展从应用性能、微生物机制、经验模型到潜在挑战均缺乏系统性综述。将固体碳源分为合成碳源、天然碳源和共混碳源3类,并分别对这3类碳源应用的影响因素进行讨论,提出了高效运行策略;随后对微生物机制和经验模型进行综述,指出了后续深入研究的方向;最后对冶金、矿场等重金属工业园区生活污水处理所面临的挑战提出了应对措施和建议。系统性对固体碳源应用进展进行了综述,可为后续该技术的应用和改进提供参考。The low carbonization of wastewater in China has caused the low efficiency of biological nitrogen removal technology.The solid carbon source,as a carrier,provides an electron donor to enhance the denitrification process.However,there are few systematic reviews on solid carbon sources’performances in application,microbial mechanism,empirical model and potential challenges.This paper divides solid carbon sources into synthetic,natural and blended categories and then investigates the factors affecting the application of these three types of carbon sources.Then,it proposes a more efficient operation strategy.A review of the microbial mechanism and empirical model show further research is still needed.To address the challenges faced by wastewater treatment in metal industrial parks and mines,it puts forward some countermeasures and suggestions.This paper may provide some references for the application and improvement of this technology.
