摘　　要：通过模拟试验初步研究利用管式微滤膜,以循环过滤、间歇反冲洗的方式处理高固含量海水。考察了不同海水浓度与跨膜压差条件下,膜元件渗透水通量、产水淤泥密度指数、浊度、膜污染指数的变化,初步探究了采用管式微滤膜作为高固含量特殊环境海水淡化预处理工艺的可行性。The treatment of high solid content seawater with tubular microfiltration membrane by circulating filtration and intermittent backwashing was studied.The changes of permeate flux,sludge density index,turbidity and membrane fouling index of membrane components under different seawater concentrations and transmembrane pressure were investigated.The feasibility of tubular microfiltration membrane as a pretreatment process for seawater desalination in special environments with high solid content was preliminarily explored.
