電鍍廢水除鎳樹脂型號齊全

一、樹(shu)脂(zhi)(zhi)(zhi)的運輸(shu)(shu)和(he)貯(zhu)(zhu)存(cun)：離子交換樹(shu)脂(zhi)(zhi)(zhi)內含(han)有(you)一定(ding)(ding)量(liang)的水(shui)份(fen)，在(zai)運輸(shu)(shu)及貯(zhu)(zhu)存(cun)過程(cheng)中(zhong)(zhong)應(ying)盡量(liang)保持(chi)這部分水(shui)份(fen)。如果貯(zhu)(zhu)存(cun)過程(cheng)中(zhong)(zhong)樹(shu)脂(zhi)(zhi)(zhi)脫了水(shui)，應(ying)先用濃食(shi)鹽水(shui)（8-10%)浸(jin)泡1-2小時，再(zai)逐(zhu)漸稀釋，不得直接(jie)放于水(shui)中(zhong)(zhong)，以免樹(shu)脂(zhi)(zhi)(zhi)急劇膨脹而破碎。樹(shu)脂(zhi)(zhi)(zhi)在(zai)貯(zhu)(zhu)存(cun)或(huo)運輸(shu)(shu)過程(cheng)中(zhong)(zhong)，應(ying)保持(chi)在(zai)5-40℃的溫度環境中(zhong)(zhong)，避免過冷或(huo)過熱(re)，影(ying)響質量(liang)。若冬季沒有(you)保溫設(she)備時，可(ke)(ke)將樹(shu)脂(zhi)(zhi)(zhi)貯(zhu)(zhu)存(cun)在(zai)食(shi)鹽水(shui)中(zhong)(zhong)，食(shi)鹽水(shui)的溫度可(ke)(ke)根據氣溫而定(ding)(ding)。

　　二、新樹(shu)(shu)(shu)脂(zhi)(zhi)的予處(chu)理：新樹(shu)(shu)(shu)脂(zhi)(zhi)常含有溶(rong)劑、未參加(jia)聚(ju)合反應的物質和少量低(di)聚(ju)合物，還可能(neng)吸著(zhu)鐵、鋁、銅等(deng)重(zhong)金屬離子。當樹(shu)(shu)(shu)脂(zhi)(zhi)與(yu)水、酸、堿或(huo)其它溶(rong)液相接(jie)觸時，上述可溶(rong)性雜質就(jiu)會轉(zhuan)入溶(rong)液中(zhong)，在使用(yong)初期(qi)污染(ran)出水水質。所以，新樹(shu)(shu)(shu)脂(zhi)(zhi)在投運前(qian)要進行預處(chu)理。

電鍍廢水除鎳樹脂型號齊全 不同軟化水設備的一切工序十分挨近，僅僅因為實踐工藝的不同或操控的需求，可能會有一些附加的流程。任何故鈉離子交流為根底的軟化水設備都是在這五個流程的根底上開展來的(其間，全自動軟化水設備會添加鹽水重注進程)。作業(有時叫做產水，下同)、反洗、吸鹽(再生)、慢沖刷(置換)、快沖刷五個進程。 慢沖刷 在用鹽水流過樹脂今后，用原水以相同的流速慢慢將樹脂中的鹽悉數沖刷潔凈的進程叫慢沖刷，因為這個沖刷進程中仍有很多的功能基團上的鈣鎂離子被鈉離子交流，依據實踐經歷，這個進程中是再生的首要進程，所以很多人將這個進程稱作置換。這個進程一般與吸鹽的時刻相同，即30分鐘左右。 快沖刷 為了將殘留的鹽*沖刷潔凈，要選用與實踐作業挨近的流速，用原水對樹脂進行沖刷，這個進程的zui終出水應為合格的軟水。一般情況下，快沖刷進程為5-15分鐘。 反洗 鍋爐軟化水001*7陽離子樹脂交換過程，作業一段時刻后的設備，會在樹脂上部阻攔很多由原水帶來的污物，把這些污物除去后，離子交流樹脂才干*曝露出來，再生的效果才干得到確保。反洗進程就是水從樹脂的底部洗入，從頂部流出，這樣能夠把頂部阻攔下來的污物沖走。這個進程一般需求5-15分鐘左右。 鍋爐軟化水001*7陽離子樹脂交換過程，吸鹽 行將鹽水注入樹脂罐體的進程，傳統設備是選用鹽泵將鹽水注入，全自動的設備是選用的內置噴射器將鹽水吸入(只需進水有必定的壓力即可)。在實踐作業進程中，鹽水以較慢的速度流過樹脂的再生效果比單純用鹽水浸泡樹脂的效果好，所以軟化水設備都是選用鹽水慢速流過樹脂的辦法再生，這個進程一般需求30分鐘左右，實踐時刻受用鹽量的影響。
