Carrousel氧化沟同步硝化反硝化的影响因素研究
Study on the Impact Factors of Simultaneous Nitrification and Denitrification in a Carrousel Oxidation Ditch
摘要
Abstract
[ Objective ] The research aimed to provide reference for the nitrogen removal optimization and energy - saving operation of urban sewage plant. [ Method] A pilot - scale Carrousel oxidation ditch with effective volume of 240 L was used for the simulated wastewator treatment. The influences of dissolved oxygen(DO), COD loading of influent and ammonia loading of influent on simultaneous nitrification and denitrification (SND) in the Carrousel oxidation ditch was investigated. [ Result] Considering the removal rate of ammonia nitrogen and total nitrogen, the optimum DO concentration for meeting the demands of SND was 1.0 mg/L and the the optimum COD loading of influent was 0.25 kgCOD/( kgMLSS · d) . The smaller ammonia loading of irfluent was conducive to SND. [ Conclusion] DO is the decisive factor of SND occurring in Carrousel system. The affecting of COD loading of influent on the process of SND is mainly reflected in the limits of the achievement of good nitrification.关键词
