I-Polyaluminium chloride sisicoci samanzi esisebenza kakuhle kakhulu, esinokucolisa, sisuse amavumba, sikhuphe umbala, njl.njl iindleko zingagcinwa ngaphezu kwe-40%.Ibe sisicoci samanzi esigqwesileyo esaziwayo ekhaya nakwamanye amazwe.Ukongeza, i-polyaluminium chloride inokusetyenziselwa ukucoca umgangatho wamanzi okhethekileyo onje ngamanzi okusela kunye nonikezelo lwamanzi etephu, njengokususwa kwentsimbi, ukususwa kwecadmium, ukususwa kwefluorine, ukususwa kongcoliseko lweradioactive, kunye nokususwa kwe-oyile etyibilikayo.
PAC (Poly Aluminiyam Chloride) Iimpawu:
I-Polyaluminium chloride iphakathi kwe-ALCL3 kunye ne-ALNCL6-NLm] apho u-m emele iqondo le-polymerization kwaye n imele iqondo lokungathathi hlangothi kwemveliso yePAC.I-Polyaluminium chloride efinyeziweyo njenge-PAC idla ngokubizwa ngokuba yi-polyaluminium chloride okanye i-coagulant, njl.Imveliso ineempawu ezomeleleyo ze-adsorption, kwaye ngexesha lenkqubo ye-hydrolysis, iinkqubo zomzimba kunye neekhemikhali ezifana ne-coagulation, i-adsorption kunye nemvula zenzeka.
Isicelo sePAC (Poly Aluminiyam Chloride):
I-Polyaluminium chloride isetyenziselwa ukubonelela ngamanzi asezidolophini kunye nokucocwa kwamanzi: amanzi omlambo, amanzi okugcina amanzi, amanzi aphantsi komhlaba;ukucocwa konikezelo lwamanzi kwimizi-mveliso, ukucocwa kogutyulo olusezidolophini, ukufunyanwa kwezinto eziluncedo kumanzi amdaka avela kwimizi-mveliso kunye nentsalela yenkunkuma, ukukhuthaza intlenge yamalahle acoliweyo kumanzi amdaka okuhlamba amalahle, ukwenziwa kwesitatshi Ukurisayikilishwa kwesitatshi;I-polyaluminium chloride inokucoca amanzi amdaka ahlukeneyo kwimizi-mveliso, anje: ukuprinta kunye nokudaya amanzi amdaka, amanzi amdaka esikhumba, amanzi amdaka anefluorine, amanzi amdaka anesinyithi, amanzi amdaka aneoyile, amanzi amdaka enziwe ngamaphepha, amanzi amdaka okuhlamba amalahle, amanzi amdaka emigodi, ukubilisa amanzi amdaka, amanzi amdaka, isinyithi esinenyama. Ukulungiswa kwamanzi amdaka, njl.;I-Polyaluminium chloride yokucoca ugutyulo: ukwenza iphepha, ukucokisa iswekile, ukubumba ukubumba, ukuthintela ukushwabana kwelaphu, umthwali wecatalyst, ukusetwa kwesamente kumayeza okucokisa ngokukhawuleza, izinto zokuthambisa zokuthambisa.
Isalathisi somgangatho wePAC (ipolyaluminium chloride)
Ziziphi ezona mpawu zintathu zibalulekileyo zomgangatho wePAC (ipolyaluminium chloride)?I-salinity, ixabiso le-PH, kunye nomxholo we-alumina ogqiba umgangatho we-polyaluminium chloride zizona zibonakaliso ezintathu ezibalulekileyo zekhwalithi ye-polyaluminium chloride.
1. Ubutyuwa.
Iqondo le-hydroxylation okanye i-alkalization yefomu ethile kwi-PAC (i-polyaluminium chloride) ibizwa ngokuba yi-degree of basicity okanye i-alkalinity.Ngokuqhelekileyo ibonakaliswa yi-molar ratio ye-aluminium hydroxide B = [OH] / [Al] ipesenti.Ityuwa yenye yezona zibonakaliso ezibalulekileyo ze-polyaluminium chloride, ehambelana ngokusondeleyo nefuthe le-flocculation.Okukhona uphezulu ugxininiso lwamanzi akrwada kwaye kokukhona ityuwa iphezulu, kokukhona isiphumo se-flocculation singcono.Ukushwankathela, kuluhlu lwe-turbidity yamanzi akrwada ye-86 ~ 10000mg / L, i-salinity ephezulu ye-polyaluminium chloride yi-409 ~ 853, kunye nezinye iimpawu ezininzi ze-polyaluminium chloride zihambelana nobutyuwa.
2. ixabiso le-pH.
I-pH ye-PAC (i-polyaluminium chloride) isisombululo nayo isalathisi esibalulekileyo.Imele inani le-OH-kwimeko ekhululekile kwisisombululo.Ixabiso le-pH le-polyaluminium chloride linyuka ngokubanzi ngokunyuka kwesiseko, kodwa kulwelo olunemixube eyahlukeneyo, akukho budlelwane buhambelanayo phakathi kwexabiso le-pH kunye nesiseko.Ulwelo olunogxininiso olufanayo lwetyuwa lunamaxabiso ahlukeneyo e-pH xa ugxininiso lwahlukile.
3. Umxholo weAlumina.
Umxholo we-alumina kwi-PAC (i-polyaluminium chloride) ngumlinganiselo wamacandelo asebenzayo emveliso, enobudlelwane obuthile kunye nobuninzi besisombululo.Ngokuqhelekileyo, okukhona ukuxinana okukhulu, kokukhona kuphezulu umxholo we-alumina.I-viscosity ye-polyaluminium chloride ihambelana nomxholo we-alumina, kwaye i-viscosity iyanda ngokunyuka komxholo we-alumina.Ngaphantsi kweemeko ezifanayo kunye noxinzelelo olufanayo lwe-alumina, i-viscosity ye-polyaluminium chloride iphantsi kune-aluminium sulfate, eyona nto ilungele ukuthutha kunye nokusetyenziswa.
