【摘要】 通过考察有机物生物降解、硝化和反硝化过程中INT-ETS活性的变化规律,研究了INT-ETS活性表征污泥生物活性的可行性。结果表明,INT-ETS活性可以有效揭示有机物生物降解、硝化和反硝化反应进程,同时对系统受到的冲击负荷和硝化过程中碱度的变化有灵敏感应,说明用INT-ETS活性表征污泥的生物活性是可行的。更多还原

【Abstract】 The changing course of INT-ETS activity during organic matter biodegradation, nitrification and denitrification was studied to evaluate the feasibility that INT-ETS activity assessed biological activity of activated sludge. The experimental results showed that INT-ETS activity could reflect the reaction course of organic matter biodegradation, nitrification and denitrification, and the change of loading and alkalinity. Therefore, INT-ETS activity could be used as a parameter to evaluate the biological activity of activated sludge.更多还原
