摘要
本文介绍了ＵＦ在化工分离中作为ＲＯ预处理的四种再生运行工艺，分别对这些工艺的试验结果进行了讨论。采用液体反冲同时在膜正面进行气液混合冲洗再生的运行工艺能显著地延长化学清洗周期，确保ＵＦ的稳定运行。
Four techniques of UF regeneration-operation in the pretreatment process of RO chemicalseparation were introduced.The experimental results for the four regeneration-operation techniques were separately discussed,and a technological measure was raised that during the backwashing for regeneration a simultaneous gas-liquid mixture compressed washing should be doneso as to markedly elongate the chemical washing cycle and assure the steady operation of a UFdevice.
