| 摘 要： | 针对中药废水具有COD高,水质变化大等特点,采用一体式膜生物反应器(MBR)对中药废水的厌氧反应器出水进行处理,在固定水力停留时间(HRT)为5 h的条件下,考察了进水COD质量浓度及污泥质量浓度(MLSS)与COD去除之间的关系.结果表明,当HRT为5 h,进水COD质量浓度小于3 000 mg/L时,膜出水COD小于30 mg/L,满足中水回用标准;当进水COD质量浓度为3 000～6 000 mg/L时,膜出水COD大于30 mg/L而小于100 mg/L,满足污水排放标准;当进水COD质量浓度大于6 000 mg/L,膜出水COD大于100 mg/L,不能满足污水排放标准.同时污泥质量浓度(MLSS)与COD去除的关系表明,为了达到更好的COD去除率,MBR的最佳MLSS应控制在7 543 mg/L. |

| Abstract: | For the feature of Herbaceous wastewater such as heavy COD and much change of water quality,anaerobic-reactor water output is disposed by using the submerged MBR and the effects of the relationship between water input COD concentration as well as MLSS and disposed COD is made on the conditions of fixed HRT of 5 h.The results show that: on the conditions of fixed HRT of 5 h,it meets the reclaimed water reuse standard that COD concentration of water input of MBR less than 3 000 mg/L leads to water output less... |
