14、一二段膜元件统一电导率增加，并且总产水电导率和表计显示基本吻合。（六）现场情况分析结论：（此结论的前提是现场反渗透设备表计监测的数据准确无误）三套反渗透设备情况非常相似，均是在2009年4月初（4月2日-到4月8日）设备停运后再次启动出现的脱盐率下降。以A套设备为例：由数据可以看出，当回收率一样、系统压差几乎没有变化的情况下，产水量和浓水量增加而脱盐率降低，这一切都完全符合膜片被氧化的症状。根据经验我方判断设备脱盐率低是膜氧化造成的。贵单位可以将具有代表性膜元件送往厂家进行染料评定试验以确诊。 膜元件一旦被氧化，系统脱盐率将不可恢复。清洗后由于清洗掉了膜表面的部分污染物，一般反而脱盐率会有所下

15、降，但是一两个月便可恢复。要想恢复膜元件的性能只有更换膜元件才能保证系统正常的脱盐率。虽然此次循环水深度处理反渗透设备脱盐率降低和我阻垢剂供应商无关，但如果需要我方会全程跟踪协助贵单位。 如果贵单位决定试洗，现场需提供一下物品：1、本方案约定的RO装置化学清洗是指单列反渗透装置清洗。2、氢氧化钠（化学纯）15kg PH试纸一本（调整PH值，由华电负责提供。3、并且清洗使所需要的电导率仪一台、PH计一台和试纸一本均由甲方提供。项目中国内蒙包头华电反渗透系统在线清洗项目主要内容反渗透设备清洗项目免费/收费免费化学清洗审批签字内蒙包头华电脱盐水车间: 年 月 日陕西汤纳水化学有限公司: 年 月 日清
