通过分析反渗透装置运行参数的变化、保安过滤器的污堵情况以及SDI微孔滤膜的截留物分析结果，判断反渗透膜主要受微生物和有机物污染，同时可能有无机盐垢形成复合污染，并据此确定了杀菌＋碱洗＋酸洗的清洗工艺。反渗透经化学清洗后进水压力大幅降低，系统出力显著提高，取得了令人满意的清洗效果。

It concluded that the reverse osmosis membrane is fouled mainly by microbes and organic pollutants basing on the analysis of operating parameters of the RO system, the fouling of cartridge filter, and the testing results of SDI filtration membrane, at the same time inorganic scaling is likely to form complex pollutants. Accordingly, the bactericide cleaning, alkaline cleaning and acid cleaning process is brought forward and put in practice. The inlet pressure drops evidently and the permeate output increases remarkably, which is a satisfying result.
