摘要/Abstract

摘要： 采用无机膜对电脱盐污水进行处理，考察了操作参数对膜通量的影响，并进行了清洗再生试验。结果表明：在温度、压力、流速等最佳操作条件下，经无机膜过滤处理后电脱盐污水中COD去除率为74.77%，悬浮物去除率高达91.67%，油的去除率为84.42%，氨氮和挥发酚含量均下降，净化效果明显；随着过滤时间的延长，无机膜的膜通量有所下降，经RYT-02清洗剂清洗后，膜通量恢复率高达97.3%。

关键词: 无机膜, 污水, 悬浮物, 膜通量

Abstract: An inorganic membrane was used to treat electric desalting wastewater. The influence of operation parameters on membrane flux was investigated, and the cleaning and regeneration experiments were carried out. The results showed that the optimum operating parameters are temperature (T+15)℃, pressure (P+100) kPa and flow rate (V+1) m/s. After filtration, the removal rate of COD, suspended solids and oil in the sewage was 74.77%, 91.67% and 84.42%, respectively. The contents of ammonia nitrogen and volatile phenol were decreased, showing the obvious effect of purification. With the extension of filtration time, the membrane flux was decreased. The recovery rate of membrane flux was as high as 97.3% after cleaning with RYT-02 cleaner.

Key words: inorganic membrane, wastewater, suspended substance, membrane flux
