重慶恒諾水處理設備有限公司從事水處理事業十多年，已成為重慶純水、超純水設備，重慶實驗室超純水設備，重慶工業電子級超純水設備,重慶實驗室廢水系統，重慶礦用水處理設備的(de)專業生產(chan)廠家，致(zhi)力于為客戶提供優(you)質的(de)水處理解決(jue)方案，今天(tian)分享周期(qi)換向電(dian)凝(ning)聚體系的(de)優(you)勢以及組成，供大家參考

傳統的(de)(de)(de)電(dian)(dian)(dian)凝(ning)聚技術多采(cai)(cai)取同(tong)種電(dian)(dian)(dian)極(ji)(ji)(ji)(ji)，在(zai)電(dian)(dian)(dian)極(ji)(ji)(ji)(ji)反應(ying)過(guo)(guo)程中(zhong)，極(ji)(ji)(ji)(ji)板(ban)(ban)易發(fa)生(sheng)鈍化(hua)(hua)(hua)，形成(cheng)致密的(de)(de)(de)鈍化(hua)(hua)(hua)膜，阻礙或停(ting)止反應(ying)的(de)(de)(de)進一步(bu)進行，降低(di)了(le)處(chu)(chu)理(li)(li)(li)(li)效率。當(dang)電(dian)(dian)(dian)極(ji)(ji)(ji)(ji)發(fa)生(sheng)鈍化(hua)(hua)(hua)現象時(shi)，會使處(chu)(chu)理(li)(li)(li)(li)效率降低(di)，耗(hao)(hao)電(dian)(dian)(dian)量(liang)增(zeng)加(jia)，處(chu)(chu)理(li)(li)(li)(li)成(cheng)本(ben)提升。由于電(dian)(dian)(dian)氧(yang)化(hua)(hua)(hua)過(guo)(guo)程中(zhong)陽(yang)極(ji)(ji)(ji)(ji)發(fa)生(sheng)溶(rong)解，陽(yang)極(ji)(ji)(ji)(ji)損耗(hao)(hao)嚴(yan)重。理(li)(li)(li)(li)論上(shang)，電(dian)(dian)(dian)極(ji)(ji)(ji)(ji)鈍化(hua)(hua)(hua)膜形成(cheng)后，當(dang)采(cai)(cai)用(yong)換向(xiang)(xiang)電(dian)(dian)(dian)源(yuan)時(shi)，可(ke)(ke)(ke)以(yi)(yi)使電(dian)(dian)(dian)極(ji)(ji)(ji)(ji)形成(cheng)的(de)(de)(de)鈍化(hua)(hua)(hua)膜發(fa)生(sheng)部(bu)分(fen)溶(rong)解，延緩電(dian)(dian)(dian)極(ji)(ji)(ji)(ji)鈍化(hua)(hua)(hua)過(guo)(guo)程，并(bing)使鈍化(hua)(hua)(hua)電(dian)(dian)(dian)極(ji)(ji)(ji)(ji)活化(hua)(hua)(hua)。同(tong)時(shi)，如果(guo)兩(liang)極(ji)(ji)(ji)(ji)均(jun)是可(ke)(ke)(ke)溶(rong)性電(dian)(dian)(dian)極(ji)(ji)(ji)(ji)，當(dang)采(cai)(cai)用(yong)周(zhou)期(qi)換向(xiang)(xiang)電(dian)(dian)(dian)源(yuan)時(shi)，兩(liang)極(ji)(ji)(ji)(ji)均(jun)可(ke)(ke)(ke)產生(sheng)具有絮凝(ning)作(zuo)用(yong)的(de)(de)(de)金(jin)(jin)屬(shu)離子(zi)，更有利于提高(gao)處(chu)(chu)理(li)(li)(li)(li)效率。基于以(yi)(yi)上(shang)原理(li)(li)(li)(li)性分(fen)析，課題組采(cai)(cai)用(yong)了(le)金(jin)(jin)屬(shu)鋁(lv)(lv)(lv)板(ban)(ban)和(he)(he)鐵(tie)板(ban)(ban)分(fen)別作(zuo)為(wei)兩(liang)極(ji)(ji)(ji)(ji)，利用(yong)周(zhou)期(qi)換向(xiang)(xiang)電(dian)(dian)(dian)源(yuan)制成(cheng)新型(xing)電(dian)(dian)(dian)化(hua)(hua)(hua)學反應(ying)器(qi)，利用(yong)電(dian)(dian)(dian)凝(ning)聚方法處(chu)(chu)理(li)(li)(li)(li)模(mo)擬染(ran)料廢(fei)(fei)水(shui)。由于采(cai)(cai)用(yong)金(jin)(jin)屬(shu)鋁(lv)(lv)(lv)作(zuo)為(wei)陽(yang)極(ji)(ji)(ji)(ji)時(shi)有可(ke)(ke)(ke)能使鋁(lv)(lv)(lv)離子(zi)在(zai)廢(fei)(fei)水(shui)中(zhong)出現剩(sheng)余(yu)影響水(shui)質，并(bing)因鋁(lv)(lv)(lv)陽(yang)極(ji)(ji)(ji)(ji)的(de)(de)(de)過(guo)(guo)度(du)溶(rong)解而加(jia)劇鋁(lv)(lv)(lv)極(ji)(ji)(ji)(ji)板(ban)(ban)損耗(hao)(hao)，通(tong)過(guo)(guo)調(diao)整兩(liang)極(ji)(ji)(ji)(ji)換向(xiang)(xiang)周(zhou)期(qi)，可(ke)(ke)(ke)以(yi)(yi)在(zai)確保(bao)高(gao)效處(chu)(chu)理(li)(li)(li)(li)廢(fei)(fei)水(shui)的(de)(de)(de)同(tong)時(shi)，有效避(bi)免廢(fei)(fei)水(shui)中(zhong)鋁(lv)(lv)(lv)離子(zi)過(guo)(guo)量(liang)存在(zai)的(de)(de)(de)問(wen)題，并(bing)減少極(ji)(ji)(ji)(ji)板(ban)(ban)的(de)(de)(de)消耗(hao)(hao)。通(tong)過(guo)(guo)對(dui)采(cai)(cai)用(yong)不(bu)同(tong)電(dian)(dian)(dian)源(yuan)、不(bu)同(tong)電(dian)(dian)(dian)極(ji)(ji)(ji)(ji)、不(bu)同(tong)換向(xiang)(xiang)方式的(de)(de)(de)對(dui)比(bi)研(yan)究，可(ke)(ke)(ke)以(yi)(yi)基于換向(xiang)(xiang)過(guo)(guo)程對(dui)于廢(fei)(fei)水(shui)處(chu)(chu)理(li)(li)(li)(li)過(guo)(guo)程和(he)(he)處(chu)(chu)理(li)(li)(li)(li)機理(li)(li)(li)(li)、極(ji)(ji)(ji)(ji)板(ban)(ban)表面結構(gou)特(te)征(zheng)、回路中(zhong)電(dian)(dian)(dian)流變(bian)化(hua)(hua)(hua)特(te)點等進行理(li)(li)(li)(li)論分(fen)析和(he)(he)驗證(zheng)，為(wei)優(you)化(hua)(hua)(hua)周(zhou)期(qi)換向(xiang)(xiang)電(dian)(dian)(dian)凝(ning)聚法處(chu)(chu)理(li)(li)(li)(li)染(ran)料廢(fei)(fei)水(shui)的(de)(de)(de)各項參數提供(gong)依據。

實驗處理裝置(zhi)采用(yong)自制(zhi)的(de)圓形無隔(ge)膜電(dian)解裝置(zhi)。電(dian)解槽(cao)材(cai)料(liao)為(wei)有機玻(bo)璃，直徑(jing)為(wei)85mm，高為(wei)90mm，有效(xiao)容積(ji)為(wei)500mL。實驗電(dian)路(lu)由電(dian)源(yuan)、電(dian)磁繼電(dian)器(qi)、時鐘繼電(dian)器(qi)、電(dian)流方向轉(zhuan)換(huan)器(qi)、磁力(li)攪拌(ban)器(qi)經導線連接(jie)而成(cheng)，通過(guo)對時鐘繼電(dian)器(qi)和(he)(he)電(dian)流方向轉(zhuan)換(huan)器(qi)的(de)調節以實現回路(lu)電(dian)流方向和(he)(he)處理時間的(de)變換(huan)。極板(ban)完全浸入溶液(ye)中，磁力(li)攪拌(ban)器(qi)在槽(cao)底進行攪拌(ban)。
