摘要
试验采用SBR工艺研究了不同盐度、NH4^＋-N、pH和温度等因素对含盐废水短程硝化反硝化的影响。发现在20～25℃，pH＞8.5条件下，通过提高进水氨氮浓度可以使亚硝化率[NO2^-／（NO2^-＋NO3^-）]达到90％以上。实验证明，亚硝酸菌有较高的耐盐性，能在高盐环境中保持良好的活性。
Several parameter which included salinity, pH, NH4^＋-N and temperature were studied to evaluate their effects to the shortcut nitrification-denitrification in the treatment of salinity wastewater with SBR process. It is found that under the condition of temperature at 20-25℃ and pH〉8. 5, the average rate of nitrosation [NO2^-/（ NO2^-＋NO3^- ）] is above 90% depending increasing the concentration of influent ammonia. The result indicated that nitrosomon have strong endurance to salinity and can keep nicer activity in the environment containing highly-concentrated salt.
