摘　　要：文章研制了一种新型可用于移动床生物膜处理方法的褶皱型微生物亲和性生物载体,并对其水动力特性及在污水处理中的应用效果分别进行了数值模拟和物理试验研究。研究结果表明:采用褶皱圆柱体结构、聚酰胺树脂-高密度聚乙烯(PA-HDPE)混合材料制作的微生物载体相较于同孔数的HDPE材料制作的传统结构微生物载体,其比表面积提升了约5.1%;在相同曝气条件下,该褶皱型微生物载体更容易充分流化;并且对污水具有良好的处理效果,对CODCr的平均去除率达87.75%,对氨氮的平均去除率达95.00%。A novel kind of microbial carriers with folded structure and high microbial affinity was developed for the moving bed biofilm treatment,and the hydrodynamic performances and wastewater treatment effectiveness of this kind microbial carriers were studied numerically and experimentally,respectively.Results showed that the specific surface area of the microbial carrier with folded cylinder structure,which made of PA-HDPE hybrid material,increased by about 5.1%comparing with the traditional microbial carrier made of HDPE with the same number of pores;The microbial carriers with folded structure were easier to fully fluidify than the traditional microbial carriers under the same aeration conditions;And the average removal rate of CODCr and ammonia nitrogen were 87.75%and 95.00%,respectively,which indicated that it had good treatment effect on wastewater treatment.
