摘要:
对比4种不同内回流比(50%,100%,150%,200%)时的化学需氧量(COD),NH+4-N和总氮(TN)的质量浓度,通过改变单一因素内回流比进行平行实验,并在最优内回流比时,检测沿程各段反应池内NO-2-N和NO-3-N的质量浓度.实验结果表明:内回流比并不是越大越好,而是有一个适当的范围;内循环式多级A/O新工艺在处理低C/N比和高NH+
Abstract:
COD, NH+4-N and total nitrogen(TN)removal efficiencies were analyzed at four different internal reflux ratios(50%, 100%, 150%, 200%), and parallel experiments were made by changing the single factor reflux ratio. The concentrations of NO-2-N and NO-3-N in the reactors along the process were detected at the optimal reflux ratio. The results showed that: the internal reflux ratio had an optimal value; the new internal cycle multistage A/O process had a unique advantage for the treatment of low C/N ratio and high NH+4-N wastewater, and the TN removal efficiency could significantly increase to more than 80%; low cost and high removal efficiency could be obtained when the internal reflux ratio was 100%; short-cut nitrification and denitrification occurred when the internal reflux ratio was 100%.
