摘要:
实验室中通过DO、pH值、进水CODcr /NH3-N(C/N)等参数的控制实现了SBR工艺中的短程硝化反硝化。在以人工玉米水为外加碳源、进水氨氮浓度100mg/L、CODcr=800mg/L的条件下,保持pH 8.0~8.2、DO 0.5 mg/L~1.0mg/L,通过对反应周期10小时内氨氮(NH3-N),亚硝基氮(NO2--N),硝基氮(NO3--N)的跟踪以及对反应周期内每小时间隔们内这些氮的不同形态的变化量的数据的分析,证实在整个系统内短程硝化反硝化是占主导地位的脱氮途径。

Shortcut nitrification—denitrifiction was achieved in SBR through
the control of technologies’ operation parameters such as DO、pH、C/N and
so on.The experiment result show that When burthen of ammonia nitrogen is
100mg/L, C/N=8, pH 8.0~8.2、DO 0.5
mg/L~1.0mg/L,
we can conform that Shortcut nitrification—denitrifyction is dominating approach
