近年來,污水(shui)處理行(xing)業政策(ce)導向明顯,我(wo)國污水(shui)凈化劑行(xing)業獲得了較快(kuai)發展,進而帶動聚合氯(lv)化鋁行(xing)業投資積極性增加,行(xing)業改建(jian)、擴建(jian)以及(ji)新(xin)建(jian)項目不斷(duan)增多。 聚氯(lv)化鋁(Poly Aluminum Chloride,PAC)又稱聚合(he)氯(lv)化鋁、聚鋁,是(shi)一種(zhong)含不(bu)同量羥(qian)基的(de)多核(he)無(wu)機高(gao)分子高(gao)效混凝(ning)(ning)劑,分子式(shi)為[Alm(OH)n(H2O)x]Cl3m-n(n≤3m),具有混凝(ning)(ning)性(xing)能(neng)好(hao)、絮體大(da)、用量少、沉淀性(xing)能(neng)好(hao)、水(shui)中堿度消耗少等優點,被廣泛用于水(shui)處理領域,是(shi)一種(zhong)公認的(de)高(gao)效優良(liang)凈(jing)水(shui)劑。 聚(ju)氯化(hua)(hua)鋁最早開始研究是(shi)在(zai)20世紀初,但其被(bei)真正用于水處(chu)理(li)領域是(shi)在(zai)20世紀70年代,彼時的(de)(de)(de)(de)中國(guo)才剛(gang)剛(gang)擺脫文(wen)化(hua)(hua)大革命的(de)(de)(de)(de)束縛,開始對聚(ju)氯化(hua)(hua)鋁進(jin)行(xing)研發(fa)。經過(guo)(guo)近半個(ge)世紀的(de)(de)(de)(de)發(fa)展,目前我國(guo)已(yi)經發(fa)展成(cheng)為(wei)全球最大的(de)(de)(de)(de)聚(ju)氯化(hua)(hua)鋁生產(chan)基地(di)之一,低廉的(de)(de)(de)(de)價格和(he)快捷(jie)的(de)(de)(de)(de)貨(huo)運(yun),使得中國(guo)聚(ju)氯化(hua)(hua)鋁產(chan)品暢銷東南亞、英國(guo)、非洲、俄(e)羅斯、美(mei)國(guo)、日(ri)本等數十(shi)個(ge)國(guo)家(jia)和(he)地(di)區,行(xing)業總產(chan)能更是(shi)超(chao)過(guo)(guo)百萬噸(dun)(折合固體含(han)量)。 聚(ju)(ju)(ju)(ju)氯(lv)(lv)(lv)化(hua)(hua)(hua)(hua)鋁(lv)(lv)主要(yao)被分為工(gong)(gong)業(ye)級(ji)(ji)聚(ju)(ju)(ju)(ju)氯(lv)(lv)(lv)化(hua)(hua)(hua)(hua)鋁(lv)(lv)、飲用水(shui)級(ji)(ji)聚(ju)(ju)(ju)(ju)氯(lv)(lv)(lv)化(hua)(hua)(hua)(hua)鋁(lv)(lv)兩(liang)類(lei),其中(zhong),工(gong)(gong)業(ye)級(ji)(ji)聚(ju)(ju)(ju)(ju)氯(lv)(lv)(lv)化(hua)(hua)(hua)(hua)鋁(lv)(lv)常被用作工(gong)(gong)業(ye)廢水(shui)和(he)(he)污泥處(chu)理的絮凝劑;飲用水(shui)級(ji)(ji)聚(ju)(ju)(ju)(ju)氯(lv)(lv)(lv)化(hua)(hua)(hua)(hua)鋁(lv)(lv)可用于飲用水(shui)和(he)(he)自來(lai)水(shui)等特殊水(shui)質的凈化(hua)(hua)(hua)(hua)處(chu)理,如除(chu)鐵、除(chu)氟、除(chu)浮油等。目前,根據新思界產業(ye)研(yan)究中(zhong)心發布的《2021-2025年聚(ju)(ju)(ju)(ju)合氯(lv)(lv)(lv)化(hua)(hua)(hua)(hua)鋁(lv)(lv)行業(ye)深度(du)市場調(diao)研(yan)及投資策(ce)略》顯示,我國聚(ju)(ju)(ju)(ju)氯(lv)(lv)(lv)化(hua)(hua)(hua)(hua)鋁(lv)(lv)主要(yao)以工(gong)(gong)業(ye)級(ji)(ji)聚(ju)(ju)(ju)(ju)氯(lv)(lv)(lv)化(hua)(hua)(hua)(hua)鋁(lv)(lv)為主,工(gong)(gong)業(ye)級(ji)(ji)聚(ju)(ju)(ju)(ju)氯(lv)(lv)(lv)化(hua)(hua)(hua)(hua)鋁(lv)(lv)產能(neng)(neng)占總產能(neng)(neng)的75%以上。 近年(nian)來(lai),污(wu)水處理(li)行(xing)業(ye)政策導向明顯(xian),我(wo)國污(wu)水凈化(hua)(hua)劑(ji)行(xing)業(ye)獲得了(le)較快發展,進而(er)帶動聚(ju)(ju)合(he)氯化(hua)(hua)鋁(lv)(lv)行(xing)業(ye)投(tou)資積極性增加,行(xing)業(ye)改建(jian)(jian)(jian)、擴建(jian)(jian)(jian)以(yi)及新建(jian)(jian)(jian)項(xiang)目(mu)(mu)不斷(duan)增多。如2019年(nian)1月(yue)(yue)(yue),凱米拉天成萬豐化(hua)(hua)學品(兗州)有(you)限公(gong)司年(nian)產4萬噸(dun)聚(ju)(ju)合(he)氯化(hua)(hua)鋁(lv)(lv)建(jian)(jian)(jian)設項(xiang)目(mu)(mu)舉(ju)行(xing)奠基慶(qing)典儀式;2019年(nian)9月(yue)(yue)(yue),廣(guang)西百(bai)色與新疆五家渠鵬翔建(jian)(jian)(jian)材有(you)限公(gong)司簽約年(nian)產25萬噸(dun)聚(ju)(ju)合(he)氯化(hua)(hua)鋁(lv)(lv)項(xiang)目(mu)(mu);2020年(nian)3月(yue)(yue)(yue),由山西洹浦(pu)化(hua)(hua)工有(you)限責(ze)任公(gong)司承建(jian)(jian)(jian)年(nian)產10萬噸(dun)聚(ju)(ju)合(he)氯化(hua)(hua)鋁(lv)(lv)項(xiang)目(mu)(mu)開(kai)工;2021年(nian)10月(yue)(yue)(yue),云南龍(long)鎂年(nian)產5萬噸(dun)聚(ju)(ju)合(he)氯化(hua)(hua)鋁(lv)(lv)項(xiang)目(mu)(mu)舉(ju)行(xing)簽約儀式。 新(xin)(xin)思界(jie)產(chan)業研究員認(ren)為,近年(nian)來(lai),我國對工(gong)業污(wu)染的治理(li)已(yi)經取得了(le)較大的進(jin)步,工(gong)業廢(fei)(fei)水(shui)排放量(liang)總體(ti)上呈下(xia)降趨(qu)勢。但社會經濟持續發(fa)展和新(xin)(xin)型(xing)城(cheng)鎮(zhen)化(hua)持續推(tui)進(jin)使得廢(fei)(fei)水(shui)排放體(ti)量(liang)仍處(chu)較高水(shui)平(ping),作(zuo)為在給水(shui)排水(shui)處(chu)理(li)中(zhong)廣泛使用(yong)的混(hun)凝凈水(shui)劑(ji),聚(ju)氯(lv)化(hua)鋁具有良(liang)好的市場前(qian)景,行業將迎來(lai)新(xin)(xin)一輪(lun)發(fa)展機遇(yu)。 |
