摘要
在成功完成亚硝酸型半硝化反应器启动的基础上,初步研究了pH、温度、FA、有机质及DO等对亚硝酸型半硝化反应过程的影响程度并确定各因素的最佳控制范围,得出亚硝酸型半硝化反应pH在8.0～8.5、温度范围为25～30℃、C/N为1.96、溶解氧浓度小于0.4mg/L时反应达到最佳状态,这为今后亚硝酸型半硝化-厌氧氨氧化脱氮技术深入的研究创造了条件。
On the basis of successful start-up of the nitrous semi-nitrification bioreactor, the effect of pH, temperature, FA, organic substances and dissolved oxygen（DO）etc, on the reactive process of nitrous seminitrification was studied, and the optimum cotrol scope of various factors was determined. The results showed that the reaction could reach the optimum state under the conditions ofpH=8.0-8.5, temperature=25-30℃, C/N=1.96, and DO concentration〈0.4mg/L; it lays the foundation for further research on nitrous semi-nitrification technique in future.
