利用管段反应器,通过连续监测一定停留时间的铁释放量,定量比较4种磷酸盐(正磷酸钠、六偏磷酸钠、磷酸氢二钠、磷酸二氢钠)分别在淡化海水(低碱度、低硬度、高氯离子等水质条件)和自来水中对于铁释放的影响。结果表明,磷酸二氢钠和六偏磷酸钠分别在淡化海水和自来水中抑制铁释放效果最好。
利用管段反應器,通過連續鑑測一定停留時間的鐵釋放量,定量比較4種燐痠鹽(正燐痠鈉、六偏燐痠鈉、燐痠氫二鈉、燐痠二氫鈉)分彆在淡化海水(低堿度、低硬度、高氯離子等水質條件)和自來水中對于鐵釋放的影響。結果錶明,燐痠二氫鈉和六偏燐痠鈉分彆在淡化海水和自來水中抑製鐵釋放效果最好。
이용관단반응기,통과련속감측일정정류시간적철석방량,정량비교4충린산염(정린산납、륙편린산납、린산경이납、린산이경납)분별재담화해수(저감도、저경도、고록리자등수질조건)화자래수중대우철석방적영향。결과표명,린산이경납화륙편린산납분별재담화해수화자래수중억제철석방효과최호。
Pipe rig tests were conducted to evaluate effects of four different phosphate(sodium orthophosphate,sodium hexametaphosphate,sodium hydrogen phosphate and sodium dihydrogen phosphate ) on iron release in desalinated water and tap water. Results show that sodium dihydrogen phosphate and sodium hexametaphosphate had the best inhibit effect on iron release in desalinated water and tap water respectively.
