| 中文摘要 |
| 一体式好氧中空纤维膜生物反应器不同操作条件下处理生活污水的试验结果表明：在膜通量10.4L/(m2·h),污泥龄20d,污泥去除负荷(COD/VSS)为0.22kg/(kg·d)的正常稳定运行条件下,该系统可在整个膜寿命期限内(3-5a)不用洗膜并得到优质出水：COD<20mg/L,NH3-N<1.0mg/L,无色无味透明,未检出大肠杆菌。其中,污泥去除负荷、系统运行稳定状况和反应器流态是影响膜清洗周期的重要因素。 |
| 英文摘要 |
| Aerated hollow fibers membrane bioreactor process for municipal wastewater treatment was researched in this paper.Results under different operating conditions show that it is technically feasible to treat domestic sewage with this system.Under stable operating conditions of flux 10.4L/(m2·h),sludge retention time 20 days and sludge removal loading rate(COD/VSS)0.22kg/(kg·d),high quality effluent (COD<20mg/L,NH3-N<1.0mg/L,no color nor odor,no E.coli)was got without any chemical washing during the whole membrane life(three to five years).Sludge removal loading rate,system stability and flow state in the bioreactor are the major factors that could affect membrane washing period. |
