一般离子交换法去除饮用水硝酸盐往往伴生再生废盐水。为了回避了再生废盐水的处理需求，用较常见的铵态氮肥（NH4 HCO3和NH4 Cl）作为再生盐，通过不同组合用于树脂再生，将其转化为富集了硝态氮的液体氮肥并改善原肥适应性。该法适用于施肥频繁量大、连片开发的城郊农业生产。
一般離子交換法去除飲用水硝痠鹽往往伴生再生廢鹽水。為瞭迴避瞭再生廢鹽水的處理需求，用較常見的銨態氮肥（NH4 HCO3和NH4 Cl）作為再生鹽，通過不同組閤用于樹脂再生，將其轉化為富集瞭硝態氮的液體氮肥併改善原肥適應性。該法適用于施肥頻繁量大、連片開髮的城郊農業生產。

Regeneration saline wastewater was produced when nitrate was removed in drinking water by ion exchange method generally. For avoidance of treatment of regeneration saline wastewater,ammonium nitrogen fertilizer such as NH4 HCO3 and NH4 Cl was used as regeneration salt,which was to regenerate resin at different rations and concentrations,and to form liquid nitrogen fertilizer enriching nitrate. Such method was fit for fertilizing contiguous suburb frequently and heavily.
