| 中文摘要: |
| 采用超滤-纳滤、 超滤-反渗透2种膜集成工艺对印染废水二级生物法的处理出水进行深度处理，比较2种不同材料和结构的超滤膜预处理的效果， 并研究了纳滤和反渗透对出水水质的影响。研究结果表明， 作为纳滤和反渗透预处理的有效手段， 超滤能有效去除部分COD。PES超滤膜综合性能较PVC超滤膜好； 在深度脱盐方面， 与反渗透膜相比纳滤膜在较低压力下即可获得较高的通量， 但产水水质稍差。虽然对1价离子的去除率差异较大， 但纳滤膜和反渗透对钙镁等2价离子的去除率相近。 |
| 英文摘要: |
| Two kinds of membrane integration processes of UF-NF and UF-RO were applied for deep treatment of the effluence from sewage treatment plant of printing and dyeing factory. The membrane performances of two kinds of UF membranes with different materials and structure were investigated in detail during the process of pretreatment. At same time, the effluence effects brought by NF and RO were studied. Research results showed UF can effectively remove partial COD as the pretreatment process of NF or RO; PES UF membrane has much better comprehensive performances than PVC UF membrane; comparing to RO, NF membrane has higher flux and a bit worse water quality while its operating pressure is low; although NF membrane presents lower removal rate for univalent ions than RO membrane, both of these membrane technologies have close removal rates to bivalent ions. |
