摘要
膜蒸馏(MD)以其操作温度及操作压力低、可处理高盐度废水、耦合利用低品味热源等优点,在炼油化工高含盐废水脱盐处理方面有着巨大的技术优势,但膜污染问题一直是膜蒸馏走向工业化应用的障碍。介绍了膜蒸馏在处理炼油化工高含盐废水中所遇到的3种膜污染类型,梳理总结了目前控制膜污染的技术方法。
Membrane distillation has significant technical advantages in the desalination of high salinity wastewater in the refining chemical industry due to its low operating temperature,low operating pressure,and abilities to treat with high salinity wastewater and utilize low value heat source.However,membrane fouling has always prevented membrane distillation from being industrialized.This study introduces three types of membrane fouling that membrane distillation encounters while treating with highly salinity effluent from the refining chemical industry,and summarizes the current technical approaches for reducing membrane fouling.
