摘　　要：近年来,有研究发现某些醌类氧化还原介体(以下简称为醌介体)可以强化污水生物脱氮效果,其研究重点主要集中于环境因素(如温度)与操作条件(如介体浓度、介体投加方式、碳氮比等)变化对不同种类醌介体应用于污水生物脱氮的影响。根据醌介体的水溶性差异,将其分为水溶性和非水溶性醌介体,分别综述了常温/低温环境下它们在污水生物脱氮领域的应用,并对其强化生物脱氮的性能及优缺点进行比较和分析,以期为增强污水脱氮过程提供一种新的思路和方法。In recent years,it was found that the wastewater biological nitrogen removal effect can be strengthened by some quinone redox mediators(quinone fixators).The research emphases focused on the effect of environmental factors(such as temperature)and operating conditions(such as mediators concentration,mediators dosing method,carbon and nitrogen ratio,etc.)on the application of different quinone fixators in biological nitrogen removal from wastewater.Quinone fixators can be divided into water‑soluble and water‑insoluble quinone fixators based on the different water‑soluble of quinone medium bodies.The applications of quinone fixators in the wastewater biological nitrogen removal field under the normal/low temperature environment were reviewed.The performance for enhancing biological nitrogen removal and advantages and disadvantages were compared and analyzed.This paper provides a new thought and method for enhancing the sewage denitrification process.
