摘 要: 以流体力学理论为基础,从膜结构的角度出发,以膜孔密度和膜孔径为主要参数建立了超滤膜过滤受污染水的膜结构参数模型,并以不同分子量分布的城市污水二级处理水为原水,对模型参数进行了拟合、验证。结果表明:膜结构参数模型能较好地反映深度处理污水的超滤膜污染过程。 Based on the hydrodynamic theory, and from the perspective of membrane structure, a model of ultrafiltration (UF) membrane structure being polluted was built, with the pore density and pore size of the membrane as the main parameters. Moreover, the secondary effluent with different molecular weight distribution was used as the raw water to fit and check these parameters. The results showed that the model could better reflect the UF membrane fouling process of the advanced sewage treatment.
