摘　　要：为了缓解市政排水的压力,提高高校校园废水的处理效果和回用效果,降低环境压力,减轻环境污染,本文使用一体式膜生物反应器对校园废水的处理进行实验研究,探讨了一体式膜生物反应器内分别添加颗粒污泥和传统絮状污泥时污泥浓度MLSS,污泥Zeta电位、污泥体积指数SVI等参数的变化。实验研究结果表明,添加了颗粒污泥的一体式膜生物反应器中的污泥浓度MLSS比添加了絮状污泥的一体式膜生物反应器中的污泥浓度MLSS增长幅度大、污泥疏水性能好、污泥沉降性能好。In order to alleviate the pressure of municipal drainage,improve improve the treatment effect of college campus wastewater,and the effect of wastewater treatment and reuse,reduce environmental pressure,and reduce environmental pollution,this article uses an integrated membrane bioreactor to conduct experiments on campus wastewater treatment in the study,the changes of sludge concentration MLSS,sludge zeta potential,sludge volume index SVI and other parameters when adding granular sludge and traditional floc sludge to the integrated membrane bioreactor are discussed.The experimental results show that the sludge concentration MLSS in the integrated membrane bioreactor with granular sludge increases more than the sludge concentration MLSS in the integrated membrane bioreactor with flocculent sludge.The sludge hydrophobic performance of the integrated membrane bioreactor with added granular sludge is better than that of the integrated membrane bioreactor with added floc sludge.The sludge settling performance in the integrated membrane bioreactor with added granular sludge is better than that in the integrated membrane bioreactor with flocculent sludge added.
