5、油点应定期(每年)补充高温润滑油脂。6.2.Contamination and Cleaning of RO Film 反渗透膜的使用及清洗6.2.1.First Use of RO Film: 新反渗透膜的初次使用The RO Film is kept in sealed plastic bags with storage mixture of 1% sodium bisulflate and 20% hydroxy-pyruvate. The bags shall have no damage before it is opened in time of installation. The
6、 film shall be put into film tube as soon as it is opened and could be used after cleaning. 反渗透膜保存在密封的塑料袋中,袋内为 1%亚硫酸氢钠和 20%羟基丙脂的混合液。在安装前 袋子应完整无损。拆封后应马上放入膜管内,清洗后即可使用。6.2.2.There may be some Residual material on the RO film after long time operation of pure water. The reasons could be ineffective pre-
7、treatment, improper control, polluted inlet water or wrong chemicals. The RO film must be cleaned in the following procedures: 由于净水长时间在 RO 膜上运行,RO 膜上会结垢。结垢的原因有:预处理系统失效,控制不当, 进水污染或使用错误的化学品。RO 膜按下列程序清洗:6.2.2.1.Prepare suitable cleaning solution with correct pH value per section 6.2.5. Be sure that all
8、 chemicals in the solution have been fully dissolved and evenly mixed to be transparent and clear solution before it is filled into the film. 准备适当的清洗液,准确的 PH 值依照 6.2.5 节.在加入清洗液之前,确认所有的化学 品已完全溶解混合均匀。6.2.2.2. The solution is filled into the film tube by low pressure and flow of pump. The pressure shal
9、l be low enough that no osmosis happens. The cleaning solution shall be first discharged and then circulated. 用泵的低压流量打入膜管,低压控制在无渗透液产生.清洗液先排放后循环。6.2.2.3. The acid will be consumed when it dissolves the inorganic sediment and its pH value shall rise by 0.5 unit. Add acid at that time until the pH valu
10、e drops by 0.5. 当酸溶解无机物沉淀时酸会消耗,PH 值升高 0.5 个单位时,需加酸直到 PH 值下降 0.5 个单位。6.2.2.4. Dipping: Shut off the pump. Dip the components in the solution for 1 hour or longer for dirt difficult to dissolve. 浸泡:关掉泵.将元件浸泡在溶液中 1 小时,如有难溶污垢可延长浸泡时间。6.2.2.5. High-speed Flushing: High-speed water flow in about 30 to 40 m
11、inutes will clear the dirt on the surface of the film. 高速冲洗:用高速水流冲洗 30 到 40 分钟,将膜表面污垢冲洗出去。6.2.2.6. The used solution will be discharged and sampled to compare with pure solution for analysis of the cleaning effect. 排除清洗液,取样与原液分析比较,确认清洗效果。6.2.2.7. The flushing water shall be purified water in tempera
12、ture of at least 20C. The cleaning solution in the film must be cleared before normal operation of the system. 用不低于 20C 的纯化水冲洗,在正常操作之前必须把膜内清洗液冲掉。6.2.2.8. Clean Again: The film shall be flushed by purified water in at least 10 minutes. Normal production can begin only after it is rinsed clean. 再清洗:用纯
13、化水冲洗膜至少 10 分钟.冲洗干净后才能开始正常的生产。6.2.3.Contamination of Reverse Osmosis Film Module 反渗透膜污染6.2.3.1. After a period of normal operation, the complex polyamide reverse osmosis film module could be contaminated by some suspends or matters difficult to dissolve in water supply such as calcium carbonate, calc
14、ium sulfate, metal oxide, silicon sediment, organic or inorganic sediments. 运行一段时期后,复合反渗透膜会受到水中悬浮物和难溶物的污染,如碳酸钙,硫 酸钙,金属氧化物,硅沉积,无机物和有机物沉积物。The character of pollutant and contaminating speed depends on the quality of the water supply. The contamination can happen quickly and needs to be monitored becau
15、se the film module can be damaged in a short period of time. 污染物的性 质及污染速度与给水有关.污染发生很快需监控,因为污染会在很短的一段时间损坏 膜。6.2.4.Elimination of Pollutant 污染物的去除The pollutant can be eliminated either chemically or physically. Therefore, the RO system shall be cleaned after daily operation in physical way of low pres

But chemical cleaning must be done if any of the following happens: 污染物能够用化学或物理的方法去除.因此,RO 系统每天运行后可以用物理冲洗的方法去除膜 表面的沉积物。6.2.4.1. The flow reduces by 10% of the normal flow even in normal pressure and temperature. 在正常的压力和温度下流量降低正常值
