摘要
采用分段进水方式,研究不同进水流量分配比对SBR工艺脱氮除磷效果的影响。结果表明:分段进水方式能够提高TN的去除效果,当进水流量分配比为5:3时,TN的去除效果最佳。分段进水方式能够提高聚磷菌的释磷效果,使出水水质中TP浓度在0.1-0.3mg/L范围。
We used step feed mode to research effect of different influent flow distribution ratio on denitrification and phosphorus removal in SBR process. The results showed that the removal efficiency of TN can be improved by step feed mode. When the distribution ratio of influent flow was 5：3, the removal efficiency of TN was the best. Step feed mode could improve the phosphorus release effect of phosphorus accumulating bacteria, and the concentration of TP in the water quality was in the range of 0.1-0.3mg/L.
