路是腳踏出來(lái)的,歷史是人寫出來(lái)的。人的每一步行動(dòng)都在書寫自己的歷史。
Road is stepped by feet, history is written by people. Every step of man is writing his own history.
梅州/云浮陰離子交換設(shè)備系統(tǒng)--給心靈一個(gè)空間!“廣州奧凱”
陰離子交換設(shè)備工作原理
Using ion exchange method, can make the water in ion cation, anion removal, with sodium chloride ( NaCl ) represents the water quality in salt of inorganic salts, basic can be reacted with the following formula:
1、陽(yáng)離子交換樹(shù)脂:R—H+Na+ R—Na+H+2、陰離子交換樹(shù)脂:R—OH+Cl- R—Cl+OH-
陽(yáng)、陰離子交換樹(shù)脂總的反應(yīng)式即可寫成:RH+ROH+NaCl——RNa+RCL+H2O
From this may see, NaCl in water have been separately resin H+ and OH- replaced, and the reaction product is H2O, it reached the removal of salt effect.
離子交換樹(shù)脂的保護(hù)
到由于樹(shù)脂在運(yùn)行中,對(duì)進(jìn)水的水質(zhì)有著一定的要求,如:水中的有機(jī)物、重金屬、余氯等,會(huì)影響樹(shù)脂的使用性能,甚至造成樹(shù)脂的直接壞死;因此在使用離子交換系統(tǒng)時(shí),應(yīng)對(duì)進(jìn)水進(jìn)行相應(yīng)的預(yù)處理。
常見(jiàn)有:砂濾→碳濾→離子交換系統(tǒng)
為了提升離子交換樹(shù)脂的使用性能,提高終端出水的水質(zhì),得到更高純度的水,因此在使用離子交換系統(tǒng)時(shí),在有預(yù)處理(砂、碳)的前提下,又對(duì)水進(jìn)行高一層的保護(hù)(如反滲透、復(fù)合床等)最終經(jīng)過(guò)深度處理的離子交換系統(tǒng),而得到高純度的水。
離子交換系統(tǒng)常見(jiàn)的問(wèn)題
1, equipment use period is short: system design is not reasonable, the influent water quality some ingredients, anion resin regeneration is not completely up2, equipment water pH deviated from the normal range: a resin tank, not completely regenerated anion resin regeneration not contaminated3, color resin: resin is subjected to heavy metals ( such as Fe ) material contamination failure4, resin regeneration not: pharmaceutical delivery quantity enough, failure, resin regeneration liquid is not clean, the regeneration of the resin is not a good layer, resin regeneration after mixing5, ion exchange system effluent standards: resin selection unreasonable, regeneration of
