傳統的(de)(de)電(dian)(dian)(dian)(dian)凝(ning)聚技術多采(cai)取同(tong)(tong)(tong)種電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)，在電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)反(fan)應過(guo)程中，極(ji)(ji)(ji)(ji)板(ban)易發(fa)生(sheng)(sheng)鈍(dun)(dun)化(hua)(hua)，形成(cheng)致(zhi)密的(de)(de)鈍(dun)(dun)化(hua)(hua)膜，阻礙(ai)或停止反(fan)應的(de)(de)進(jin)一步進(jin)行，降低了(le)處(chu)(chu)(chu)理(li)(li)效(xiao)率(lv)。當(dang)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)發(fa)生(sheng)(sheng)鈍(dun)(dun)化(hua)(hua)現象時(shi)，會使(shi)處(chu)(chu)(chu)理(li)(li)效(xiao)率(lv)降低，耗(hao)電(dian)(dian)(dian)(dian)量(liang)增(zeng)加(jia)，處(chu)(chu)(chu)理(li)(li)成(cheng)本提升。由于(yu)電(dian)(dian)(dian)(dian)氧化(hua)(hua)過(guo)程中陽極(ji)(ji)(ji)(ji)發(fa)生(sheng)(sheng)溶(rong)(rong)解，陽極(ji)(ji)(ji)(ji)損(sun)耗(hao)嚴重。理(li)(li)論上，電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)鈍(dun)(dun)化(hua)(hua)膜形成(cheng)后，當(dang)采(cai)用換(huan)(huan)向(xiang)電(dian)(dian)(dian)(dian)源時(shi)，可以使(shi)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)形成(cheng)的(de)(de)鈍(dun)(dun)化(hua)(hua)膜發(fa)生(sheng)(sheng)部分(fen)溶(rong)(rong)解，延緩電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)鈍(dun)(dun)化(hua)(hua)過(guo)程，并使(shi)鈍(dun)(dun)化(hua)(hua)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)活化(hua)(hua)。同(tong)(tong)(tong)時(shi)，如果兩(liang)(liang)極(ji)(ji)(ji)(ji)均(jun)是可溶(rong)(rong)性(xing)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)，當(dang)采(cai)用周(zhou)期(qi)換(huan)(huan)向(xiang)電(dian)(dian)(dian)(dian)源時(shi)，兩(liang)(liang)極(ji)(ji)(ji)(ji)均(jun)可產生(sheng)(sheng)具(ju)有絮凝(ning)作(zuo)用的(de)(de)金(jin)屬離(li)子(zi)(zi)，更有利(li)于(yu)提高處(chu)(chu)(chu)理(li)(li)效(xiao)率(lv)。基(ji)于(yu)以上原理(li)(li)性(xing)分(fen)析，課題組采(cai)用了(le)金(jin)屬鋁(lv)板(ban)和鐵板(ban)分(fen)別作(zuo)為(wei)兩(liang)(liang)極(ji)(ji)(ji)(ji)，利(li)用周(zhou)期(qi)換(huan)(huan)向(xiang)電(dian)(dian)(dian)(dian)源制成(cheng)新型電(dian)(dian)(dian)(dian)化(hua)(hua)學(xue)反(fan)應器，利(li)用電(dian)(dian)(dian)(dian)凝(ning)聚方法(fa)處(chu)(chu)(chu)理(li)(li)模擬染(ran)料廢(fei)水。由于(yu)采(cai)用金(jin)屬鋁(lv)作(zuo)為(wei)陽極(ji)(ji)(ji)(ji)時(shi)有可能使(shi)鋁(lv)離(li)子(zi)(zi)在廢(fei)水中出現剩余影(ying)響水質，并因鋁(lv)陽極(ji)(ji)(ji)(ji)的(de)(de)過(guo)度溶(rong)(rong)解而加(jia)劇鋁(lv)極(ji)(ji)(ji)(ji)板(ban)損(sun)耗(hao)，通過(guo)調整兩(liang)(liang)極(ji)(ji)(ji)(ji)換(huan)(huan)向(xiang)周(zhou)期(qi)，可以在確保高效(xiao)處(chu)(chu)(chu)理(li)(li)廢(fei)水的(de)(de)同(tong)(tong)(tong)時(shi)，有效(xiao)避免廢(fei)水中鋁(lv)離(li)子(zi)(zi)過(guo)量(liang)存(cun)在的(de)(de)問題，并減少極(ji)(ji)(ji)(ji)板(ban)的(de)(de)消耗(hao)。通過(guo)對(dui)采(cai)用不同(tong)(tong)(tong)電(dian)(dian)(dian)(dian)源、不同(tong)(tong)(tong)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)、不同(tong)(tong)(tong)換(huan)(huan)向(xiang)方式的(de)(de)對(dui)比(bi)研究，可以基(ji)于(yu)換(huan)(huan)向(xiang)過(guo)程對(dui)于(yu)廢(fei)水處(chu)(chu)(chu)理(li)(li)過(guo)程和處(chu)(chu)(chu)理(li)(li)機理(li)(li)、極(ji)(ji)(ji)(ji)板(ban)表面結(jie)構特征、回(hui)路中電(dian)(dian)(dian)(dian)流(liu)變化(hua)(hua)特點等進(jin)行理(li)(li)論分(fen)析和驗證(zheng)，為(wei)優(you)化(hua)(hua)周(zhou)期(qi)換(huan)(huan)向(xiang)電(dian)(dian)(dian)(dian)凝(ning)聚法(fa)處(chu)(chu)(chu)理(li)(li)染(ran)料廢(fei)水的(de)(de)各項參數提供依(yi)據。
