摘要
利用批量实验模拟SBR反应器中的硝化反硝化反应,考察不同温度、pH值、溶解氧(ρDO),碳氮比(COD/NH3)对同步硝化反硝化脱氮效率的影响。研究表明,在温度为30℃,ρDO为5 5mg/L,pH为7 0,碳氮比为20 7时总氮去除率可达48 7%;同时可以推断活性污泥中可能同时存在异养硝化菌和好氧反硝化菌。
By simulating sequencing batch reactor,investigations were made into the effect of temp,pH,DO,the ratio of influent carbon to nitrogen on nitrogen removal and simultaneous nitrification and denitrification.It was found that a higher ratio of influent carbon to nitrogen,pH=70,DO=55mg/L,and t=30℃,could produce higher total nitrogen removal efficiency(about 467%).Conclusion was drawn from the experimental results that there might coexist heterotrophic nitrifiers and aerobic denitrifiers inside the activated sludge flocs.
