Abstract:
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.
