摘　　要：本文主要研究了UHP-RO作为一种新型低能耗的高浓盐水处理技术用于制浆废水“零排放”工艺的可行性。实验结果表明,UHP-RO的浓缩倍数为2倍较佳,且污染物主要为硫酸盐伴随微量有机物或微生物,膜污染去除需多次清洗与长时间浸泡。另外,UHP-RO的能耗约4.6kw/T,较工程现有ED低54%。This paper mainly studies the feasibility of using UHP-RO as a new low energy consumption and high condense multiple technology in“zero discharge”process of pulping wastewater.The results showed that the condense multiple of 2 times is better,and the contaminant is mainly sulfate with trace organic matter or microorganism.Membrane fouling removal requires repeated cleaning and long time immersion.In addition,the energy consumption of UHP-RO is about4.6 kW/T,which is 54%lower than the ED.
