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( ??DO) , 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 ?? , ??DO为5?? 5 mg/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。
Abstract:
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 denitrificat ion. It w as found that a higher ratio of influent carbon to nitrogen, pH = 7.0, DO= 5.5 mg/ L, and t = 30 ℃ , could produce higher total nitrogen removal ef ficiency ( about 46.7%) . Conclusion was drawn from the experimental results that there might coexist heterot rophic nit rif iers and aerobic denit rifiers inside the activated sludge flocs.
