| 摘 要： | 混凝、粉末活性炭(PAC)与超滤膜联用对微污染原水中的浊度、有机物等有很高的去除率.经过550 min的连续运行后,其组合工艺的出水浊度仍稳定在0.350 NTU,对UV254和TOC的去除率稳定在60%和40%.通过对膜过滤特性的研究可知,组合工艺中超滤膜过滤性能经过短暂的快速下降阶段后一直处于较稳定状态.膜污染由小分子有机物引起.

| Abstract: | The process of coagulation-hollow fibre ultrafiltration integrated with particle active carbon can remove turbidity and organic matters in micro-polluted water effectively. The turbidity of this combined membrane reactor's effluent was always stabilized on 0.350 NTU and the removal rates of UV_(254) and TOC were respectively about 60% and 40% after the reactor worked 550 minutes continuously. The filtration behavior of UF in this process is steady after a brief degressive phase. The cleaning experiment showed that the fouling was mainly produced by the small molecule organic. |
