Izakhiwo nemisebenzi ye-polyaluminium chloride

I-Polyaluminium chloride iyisihlanzi samanzi esisebenza kahle kakhulu, esingabulala amagciwane, sikhiphe iphunga, sikhiphe umbala, njll. Ngenxa yezici zayo ezivelele nezinzuzo kanye nebanga elibanzi lohlelo lokusebenza, umthamo ungancishiswa ngaphezu kuka-30% uma uqhathaniswa nezihlanzi zamanzi zendabuko, futhi izindleko zingagcinwa ngaphezu kwama-40%.Isiphenduke isihlanzi samanzi esihle kakhulu esiqashelwa ekhaya naphesheya.Ngaphezu kwalokho, i-polyaluminium chloride ingase isetshenziselwe ukuhlanza ikhwalithi yamanzi ekhethekile njengamanzi okuphuza kanye nokunikezwa kwamanzi kampompi, njengokukhishwa kwe-iron, ukukhishwa kwe-cadmium, ukukhishwa kwe-fluorine, ukukhishwa kwe-radioactive pollutant, kanye nokususwa kwe-oyili.

Izici ze-PAC (Poly Aluminium Chloride):

I-Polyaluminium chloride iphakathi kwe-ALCL3 ne-ALNCL6-NLm] lapho u-m emelela izinga le-polymerization futhi n emele izinga lokungathathi hlangothi lomkhiqizo we-PAC.I-Polyaluminium chloride efushanisiwe njenge-PAC ngokuvamile ibizwa nangokuthi i-polyaluminium chloride noma i-coagulant, njll. Umbala uphuzi noma uphuzi ngokukhanyayo, onsundu ngokumnyama, okumpunga okuqinile okuqinile okunenhlaka.Umkhiqizo unezakhiwo eziqinile zokukhangisa ngamabhuloho, futhi phakathi nenqubo ye-hydrolysis, izinqubo zomzimba nezamakhemikhali ezifana nokuhlangana, i-adsorption kanye nemvula zenzeka.

Isicelo se-PAC (Poly Aluminium Chloride):

I-Polyaluminium chloride isetshenziselwa ikakhulukazi ukuhlinzeka ngamanzi asemadolobheni kanye nokuhlanzwa kwe-drainage: amanzi omfula, amanzi e-reservoir, amanzi angaphansi komhlaba;ukuhlanzwa kwamanzi ezimbonini, ukuthuthwa kwendle emadolobheni, ukutholwa kwezinto eziwusizo emanzini angcolile ezimbonini nasezinsalela zemfucuza, ukugqugquzela ukuchithwa kwamalahle agayiwe emanzini angcolile okuwashwa kwamalahle, ukukhiqizwa kwesitashi Ukugaywa kabusha kwesitashi;I-polyaluminium chloride ingahlanza amanzi angcolile ahlukahlukene ezimbonini, njengalokhu: ukuphrinta nokudaya amanzi angcolile, amanzi angcolile esikhumba, amanzi angcolile ane-fluorine, amanzi angcolile anensimbi esindayo, amanzi angcolile aqukethe uwoyela, amanzi angcolile okwenza amaphepha, amanzi angcolile okugeza amalahle, amanzi angcolile ezimayini, ukuphisa amanzi angcolile, amanzi angcolile, i-meatlurgical waste. Ukucubungula amanzi angcolile, njll.;I-Polyaluminium chloride yokuhlanza indle: ukwenza usayizi wephepha, ukucwengisiswa kukashukela, ukubumba ukubunjwa, ukuvimbela ukushwabana kwendwangu, umthwali we-catalyst, ukusetha ngokushesha usimende wokucwenga, izinto zokusetshenziswa zezimonyo.

Inkomba yekhwalithi ye-PAC (i-polyaluminium chloride)

Yiziphi izinkomba ezintathu zekhwalithi ezibaluleke kakhulu ze-PAC (i-polyaluminium chloride)?Usawoti, inani le-PH, nokuqukethwe kwe-alumina okunquma ikhwalithi ye-polyaluminium chloride yizinkomba ezintathu zekhwalithi ezibaluleke kakhulu ze-polyaluminium chloride.

1. Usawoti.

Izinga le-hydroxylation noma i-alkalization yefomu elithile ku-PAC (i-polyaluminium chloride) ibizwa ngedigri ye-basicity noma i-alkalinity.Ngokuvamile kuvezwa isilinganiso se-molar se-aluminium hydroxide B=[OH]/[Al] iphesenti.I-salinity ingenye yezinkomba ezibaluleke kakhulu ze-polyaluminium chloride, ehlobene eduze nomphumela we-flocculation.Ukuphakama kwamanzi aluhlaza kanye nokwanda kosawoti, kuba ngcono umphumela we-flocculation.Ukufingqa, kububanzi be-turbidity yamanzi aluhlaza engu-86~10000mg/L, usawoti ophelele we-polyaluminium chloride ngu-409~853, nezinye izici eziningi ze-polyaluminium chloride zihlobene nobusawoti.

2. inani le-pH.

I-pH yesisombululo se-PAC (i-polyaluminium chloride) nayo iyinkomba ebalulekile.Imele inani le-OH- esimweni esikhululekile esixazululweni.Inani le-pH le-polyaluminium chloride ngokuvamile liyakhuphuka ngokwenyuka kwesisekelo, kodwa oketshezini olunezinhlanganisela ezihlukene, abukho ubuhlobo obuhambisanayo phakathi kwevelu ye-pH kanye nokuyisisekelo.Uketshezi olunokugxiliswa kosawoti ofanayo kunamanani e-pH ahlukene lapho ukugxila kuhlukile.

3. Okuqukethwe kwe-Alumina.

Okuqukethwe kwe-alumina ku-PAC (i-polyaluminium chloride) isilinganiso sezingxenye ezisebenzayo zomkhiqizo, ezinobudlelwano obuthile nokuminyana okuhlobene kwesixazululo.Ngokuvamile, uma kukhulu ukuminyana okuhlobene, kuyanda okuqukethwe kwe-alumina.I-viscosity ye-polyaluminium chloride ihlobene nokuqukethwe kwe-alumina, futhi i-viscosity iyanda ngokwanda kokuqukethwe kwe-alumina.Ngaphansi kwezimo ezifanayo kanye nokuhlushwa okufanayo kwe-alumina, i-viscosity ye-polyaluminium chloride iphansi kunaleyo ye-aluminium sulfate, ehamba phambili ekuthuthweni nasekusetshenzisweni.
