有机负荷冲击对微压反应器的影响及调控策略

通过单周期瞬时有机负荷（OLR）冲击试验，探究了OLR冲击对微压内循环反应器（MPR）去除效率的影响，采用提高曝气量的方式应对冲击，确定不同OLR冲击条件下的最适曝气量.结果表明，随着OLR的增加，出水COD低于50mg/L，出水TN低于10mg/L，但NH₄⁺-N和TP的去除效率随负荷增加而降低.OLR增加到0.26gCOD/（gMLSS·d）时出水TP高于0.5mg/L；OLR增加到0.46gCOD/（gMLSS·d）时出水NH₄⁺-N高于5mg/L.OLR分别为0.26，0.34，0.46gCOD/（gMLSS·d）时，相应最适曝气量分别为1.95，2.25，2.45L/min.在单周期OLR冲击下，通过调控曝气量的方式可以有效应对冲击，保证污染物去除效果.

The impact of organic load on the micro-pressure swirl bioreactor and its control strategy

Through a single-cycle instantaneous organic load rate (OLR) shock test, the influence of OLR shock on the micro-pressure swirl bioreactor (MPR) removal efficiency was explored. And adopt the method of increasing the aeration rate to deal with the shock, and determine the optimal aeration rate under different OLR shock conditions. The results showed that with the increase of OLR, the effluent COD was less than 50mg/L and the effluent TN was less than 10mg/L, but the removal efficiency of NH₄⁺-N and TP decreased as the load increased. OLR increased to 0.26gCOD/(gMLSS·d), the effluent TP was higher than 0.5mg/L, and when it was increased to 0.46gCOD/(gMLSS·d), the effluent NH₄⁺-N was higher than 5mg/L. When OLR is 0.26, 0.34, 0.46gCOD/(gMLSS·d), the corresponding optimal aeration volume is 1.95, 2.25, 2.45L/min, respectively. Under a single-cycle OLR shock, the influence could be effectively dealt with by adjusting the amount of aeration to ensure the removal of pollutants.
