介绍了国产PVDF复合膜及新型外置浸没式膜组件在焦化废水深度处理中的应用。 PVDF复合膜在确保通量的前提下，避免了物理损伤带来的断丝、出水悬浮物超标等问题。新型膜组件具有占地面积小、自动化程度高等优点，其出水可以直接回用或作为反渗透膜的进水。%This paper introduces the application of China-made PVDF composite membrane and new type external submerged membrane module in advanced treatment of coke plant wastewater. PVDF has avoided the problems of wire break and exceeding amount of suspended solid in discharged water on condition of ensuring the flux. The new type membrane module has advantages of less space occu-pation and higher automation level,and the discharged water could be directly reused or used as feed water for reverse osmosis membrane.
