)使EDI過(guò)程出現不同的現象。國內外絕大多數EDI膜堆均使用強酸、強堿性離子交換樹(shù)脂。</p><p><br/></p><p>這類(lèi)EDI膜塊的樹(shù)脂的離子交換能力較強，再生也相對容易。而弱酸、弱堿性樹(shù)脂雖然容易被H+和OH-所再生，但再生后樹(shù)脂的離子交換能力變弱，因而較少被采用。</p><p><br/></p><p>EDI膜塊廠(chǎng)家介紹，這主要是由弱酸、弱堿性樹(shù)脂的選擇吸附性決定的。在中性水溶液中，弱酸、弱堿性樹(shù)脂對各種離子的選擇性吸附順序為：H+>>Fe3+>Ca2+>Mg2+>K+>Na+>Li+；OH->>SO42->PO43->NO2->Cl->HCO3-。</p><p><br/></p><p>可以看出弱酸、弱堿性樹(shù)脂對H+、OH-的選擇性系數明顯高于其它離子，使得再生后樹(shù)脂上的H+、OH-不易與溶液中其它離子進(jìn)行交換。</p><p><br/></p><p>因而，EDI膜塊廠(chǎng)家分析，再生后的樹(shù)脂，離子交換能力變弱，樹(shù)脂的離子交換、再生過(guò)程不能持續高效進(jìn)行，ZUI終影響膜堆的脫鹽率。</p>
