style="line-height: 1.75em;"><strong>反渗透膜的清洗</strong></p><p style="line-height: 1.75em; text-indent: 2em;">根据经验，如果反渗透装置每隔三个月或更长时间清洗一次。如果是1-3个月清洗一次，则需要改进运行工况，提高预处理效果。</p><p style="line-height: 1.75em;"><strong>判断清洗的情况</strong></p><p style="line-height: 1.75em;">（1）标准化的淡水产量下降了10%以上。</p><p style="line-height: 1.75em;">（2）标准化的透盐率增加了10%以上。</p><p style="line-height: 1.75em;">（3）为了维持正常的淡水流量，经温度校准后给水与浓水间的压差增加了10%以上。</p><p style="line-height: 1.75em;">（4）内部装置有严重污染物和结垢物。</p><p style="line-height: 1.75em;">（5）RO装置长期停用前。</p><p style="line-height: 1.75em;">（6）RO装置例行维护。</p><p style="line-height: 1.75em;"><strong>判断是否对反渗透系统实施清洗前，还应综合考虑以下一些可能产生上述现象的其他原因：</strong></p><p style="line-height: 1.75em;">（1）操作压力下降（压力控制装置失灵和高压泵出现异常）。</p><p style="line-height: 1.75em;">（2）进水温度降低（加热器故障，或季节变化引起水温降低）。</p><p style="line-height: 1.75em;">（3）进水含盐量升高。</p><p style="line-height: 1.75em;">（4）预处理异常。</p><p style="line-height:
