| 摘 要： | 采用0.45μm微滤膜、不同截留分子质量的超滤膜(100、80、50,30.10、5 kDa)以及不同型号的纳滤膜(NF90、NF270、NF70)为试验用膜,并将这些膜进行优化组合,直接处理浙江省某流域河水.结果表明,采用0.45μm微滤膜、截留分子质量5kD的超滤膜作为预处理工艺,经NF90处理后,COD_(Mn)去除率达到89%,离子的去除率达到83%.采用直接膜处理工艺,可用微滤、超滤替代传统给水处理中的混凝、过滤、沉淀及澄清处理等微污染水预处理工艺,集成膜分离技术能很好地实现对微污染原水的彻底处理,出水水质稳定安全,完全达到健康饮用水标准.

| Abstract: | Treatment of micro-polluted water by hybrid membrane technology of microfiltration membrane of 0.45 μm, MWCO100, 80, 50, 30, 10,5 kD ultrafiltration membrane and NF90, NF270 and NF70. The results showed that after pretreatment process of microfiltration membrane of 0.45μm and MWCO 5 kD ultrafiltration membrane, the removal of COD_(Mn) and of water are 89% and 83% after treatment by NF90, respectively. The hybrid membrane technology can treat the micro-polluted raw water effectively, and the water quality is stable and accords with the standard of the drinking water. |
