厌氧氨氧化与反硝化除磷耦合机制

Coupling mechanism of anaerobic ammonia oxidation and denitrifying phosphorus removal

厌氧氨氧化与反硝化除磷的耦合对实现污水同步脱氮除磷和推动其实际应用具有重要意义。在深入分析厌氧氨氧化与反硝化除磷机理的基础上,充分讨论了厌氧氨氧化与反硝化除磷的微生物菌群关系及影响两者耦合的控制因素。分析得出,控制系统在温度为30～35℃,DO为0.2～0.5 mg/L,pH为7.5～8.0,进水有机物质量浓度在100～200 mg/L的条件下运行,有利于实现两者的耦合。

The coupling of anaerobic ammonium oxidation and denitrifying phosphorus removal is of great significance to the realization of simultaneous denitrification and dephosphorization of wastewater and the acceleration of practical application.Based on the in-depth analysis on the mechanisms of anaerobic ammonium oxidation and denitrifying phosphorus removal,the micro-flora relationship between both anaerobic ammonium oxidation and denitrifying phosphorus removal and the control factors affecting the coupling of both processes are fully discussed.It is known through analysis that it is beneficial to the realization of the coupling of both processes,when the reaction conditions are as follows:the temperature is 30-35℃,DO 0.2-0.5 mg/L,pH 7.5-8.0,and the mass concentration of influent organic substances are 100-200 mg/L.
