  • 摘要: 采用膜生物反应器进行含酚废水的处理，探讨投加好氧颗粒污泥对反应器中污泥性能的影响。结果表明，在膜生物反应器中投加好氧颗粒污泥能有效改善污泥性能，提高处理效果。从采用絮状污泥到逐渐增加好氧颗粒污泥投加量为100%的过程中，反应器中污泥浓度明显提高，MLSS由5 582 mg/L增加到8 168 mg/L；沉降性能得到改善，SVI由135.85 mL/g下降到29.36 mL/g；疏水性增强，Zeta电位由-20.302 mV升高到-4.325 mV；对含酚废水中COD、NH3-N的降解能力明显提高，COD、NH3-N、NO3-N去除率分别由87.3%、83.2%、55.3%增加到99.2%、94.9%、66.3%。改善了膜污染现象，膜通量衰减率由63.3%降低到42.8%。用二元多项式三维回归分析，得到污染物去除率关于好氧颗粒污泥投加量和反应器运行时间的二元方程，对指导好氧颗粒污泥膜生物反应器的连续运行具有重要意义。
    Abstract: Sludge property was analyzed while aerobic granular sludge were added into membrane bio-reactor(MBR)during phenolic wastewater treatment. The results showed that sludge physical property was improved, and sludge biodegradable ability was enhanced. In the process of adding aerobic granular sludge into MBR gradually from 0 to 100 percent, MLSS concentration rised from 5 582 mg/L to 8 168 mg/L, SVI decreased from 135.85 mL/g to 29.36 mL/g,Zeta potential increased from -20.302 mV to -4.325 mV,meanwhile the removal rate of COD, NH3-N, NO3-N increased from87.3%, 83.2%, 55.3% to 99.2%, 94.9%, 66.3%, respectively.The membrane fouling slowed down, the attenuation of membrane flux declined from 63.3% to 42.8%. The bivariate equation was simulated by using three-dimensional regression analysis, it states the relativity between removal rate of pollutants and aerobic granules dosage as well as running time of reactor, which is significant to the continious operation of aerobic granular sludge membrane bio-reactor.
