摘要

摘要: 探究NH₄⁺-N冲击对微压反应器(MPR)污染物去除效率的影响,通过提高单周期瞬时进水NH₄⁺-N浓度至40,50 mg/L,对MPR进行冲击。结果表明:常规负荷下,MPR具有良好的污染物去除效果。冲击周期降解历时数据显示,在进水40 mg/L NH₄⁺-N冲击周期内进水ρ(COD)、ρ(NH₄⁺-N)、ρ(TP)分别为192.58,40.96,2.52 mg/L,出水分别为38.16,0.70,0.26 mg/L,去除效果无显著变化,出水TN浓度上升至16.04 mg/L。增加NH₄⁺-N冲击浓度至50 mg/L,冲击周期内NH₄⁺-N降解速率不变,反硝化速率提高,出水ρ(NH₄⁺-N)、ρ(TN)升高至4.95,17.62 mg/L,TN降解主要受碳源不足影响;TP去除效果无变化,冲击后57个周期内除磷系统受到影响,出水TP出现较大波动,最高浓度达到2.6 mg/L。以上结果表明,MPR系统受到NH₄⁺-N冲击后1个周期内,脱氮性能即可恢复,说明冲击对脱氮系统造成了可逆的短期影响,但对除磷系统造成不可逆的长期影响。

Abstract: The effect of NH₄⁺-N shock on pollutants' removal efficiency of the micro-pressure reactor (MPR) was investigated by increasing the single cycle instantaneous influent NH₄⁺-N concentration to 40 and 50 mg/L and shocking the MPR. The results showed that the MPR had a good pollutant removal effect under conventional load. The degradation epoch of the shock cycle showed that in the influent 40 mg/L NH₄⁺-N shock cycle, the influent concentrations of COD, NH₄⁺-N, and TP were 192.58, 40.96, and 2.52 mg/L, and the effluent concentrations were 38.16, 0.70, and 0.26 mg/L, respectively, with no significant changes in the removal effect, and the effluent TN concentration increased to 16.04 mg/L. When the NH₄⁺-N concentration shock was increased to 50 mg/L, the NH₄⁺-N degradation rate remained unchanged and the denitrification rate increased during the impact cycle, and the effluent NH₄⁺-N and TN concentrations increased to 4.95 and 17.62 mg/L. TN degradation was mainly affected by the lack of carbon source, and there was no change in TP removal effect. The above results showed that the nitrogen removal performance of the MPR system recovered within 1 cycle after the impact of NH₄⁺-N, indicating a reversible short-term effect on the nitrogen removal system. An irreversible long-term effect on the phosphorus removal system was observed.
