　　1、樹脂(zhi)失效后，充分反(fan)洗樹脂(zhi)層。

　　2、配制(zhi)15～25NaCl溶液，將該濃鹽水導(dao)入交換器(qi)內(nei)，直到樹(shu)脂內(nei)沒有空氣為(wei)止。

　　3、在今(jin)后(hou)投(tou)運(yun)該(gai)交換器時(shi)，必須逐漸(jian)地降低鹽水的(de)濃(nong)度，減少樹(shu)脂滲透壓(ya)的(de)沖擊。

　　4、投(tou)運前(qian)，必須對該樹脂(zhi)床進(jin)行兩倍或三(san)倍的再生(sheng)。對于凝結(jie)水或超純(chun)水系統的混床樹脂(zhi)，必須將樹脂(zhi)轉化(hua)成再生(sheng)后的狀態(tai)。

　　5、將樹脂分層，執行雙(shuang)倍再(zai)生(sheng)。

　　6、沖洗(xi)掉再生劑并使樹脂置于沖洗(xi)水中。

　　7、定期置換樹脂(zhi)內的存水(shui)(每周一次)，除去任何TOC溶出物。

　　8、投運(yun)前(qian)，按(an)正常方(fang)式沖(chong)洗和再生樹脂。
