采用缺氧/好氧序批式膜生物反应器(SBMBR)处理腈纶废水,考察不同运行条件下反应器对废水COD(化学需氧量)、NH4+-N和TN(总氮)的去除效率,以及活性污泥微生物和膜污染特征.结果表明,SBMBR对腈纶废水污染物具有很高的去除效果,在水力停留时间为24 h、90 min缺氧/150 min好氧交替运行的条件下,COD、NH+-N和TN的平均去除率分别为82.5％、98.7％和74.6％,出水水质可以稳定达到国家污水综合排放标准(GB 8978-1996)-级标准;碳源和碱度不足是影响脱氮效果的主要因素,外加碳源和碱度可以显著提高脱氮效率;反应器内微生物主要有丝状菌、短杆菌和球菌,进水C/N过低会导致丝状菌大量生长;聚偏氯乙烯(PVDF)平板膜表现出较强的抗污染能力,污染后的膜表面经物理清洗后,膜通量基本可以完全恢复.
