| 摘 要： | 以我国北方某改良型A2/O工艺 (设计规模6×104 m3·d−1) 为例，基于一年的运行数据，考察碳源储存与生物脱氮除磷能力之间的关系，分析碳源利用效率和能耗情况。结果表明：在7—9月，系统碳源的综合利用效率为53%~55%，这说明消耗的碳源中超过50%比例用于生物脱氮除磷；反硝化菌较聚磷菌对环境的变化更敏感；外加碳源的延伸成本占直接成本的20.5%。因此，污水处理厂应充分考虑进出水水质及环境条件变化对碳源有效利用的影响。本研究结果可为减污降碳协同增效背景下城市污水处理厂A2/O工艺及其他常规工艺的优化调控提供参考。

| Abstract: | Taking an improved A2/O process in northern China (with a design scale of 6×104 m3·d−1) as an example, the relationship between carbon source storage and biological nitrogen and phosphorus removal was investigated based on the operation data of a whole year, and the utilization efficiency of carbon source and energy consumption was analyzed. The results showed that from July to September, the comprehensive utilization efficiency of carbon source reached 53%~55%, which proved that more than 50% consumed carbon source was used for biological nitrogen and phosphorus removal. Denitrifying bacteria were more sensitive to environmental changes than phosphorus accumulating bacteria. The extension cost of additional carbon source accounted for 20.5% of the direct cost. It was pointed out that the sewage treatment plant should fully consider the influence of the change of inlet and outlet water quality and environmental conditions on the effective utilization of carbon sources, so as to provide technical guidance and reference for the regulation and operation of municipal wastewater treatment plant with A2/O process and other conventional processes. |
