Ziziphi ii-flocculants eziqhelekileyo ze-cationic?

Unyango lwamanzi luyinxalenye ebalulekileyo yolawulo lokusingqongileyo, ukuqinisekisa ukuba amanzi akhuselekile ukusetyenziswa kunye nokusetyenziswa kwimizi-mveliso. Enye yezinto ezibalulekileyo kule nkqubo kukusetyenziswa kwee-flocculants—iikhemikhali ezikhuthaza ukuhlanganiswa kwee-slimps zibe zii-clusters ezinkulu, okanye ii-floc, ezinokususwa ngokulula emanzini. Phakathi kweentlobo ngeentlobo zee-flocculants, ii-cationic flocculants zisebenza kakhulu ngenxa ye-positive charge yazo, esebenzisana kakhulu nee-negative charges ezifumaneka emanzini amdaka. Eli nqaku lihlola ii-cationic flocculants eziqhelekileyo ezisetyenziswa kunyango lwamanzi kunye nokusetyenziswa kwazo.

IiPolyacrylamides zeCationic(CPAM)

IiCationic Polyacrylamides, ziphakathi kwezona flocculants zisetyenziswa kakhulu kushishino lokunyanga amanzi. Kubasebenzisi abaninzi, iCPAM yeyona ndlela ingcono kubo. Ezi polymers ziquka ii-subunits ze-acrylamide, ezinokulungiswa ukuba zibandakanye amaqela asebenzayo e-cationic. Ukuguquguquka kweeCationic polyacrylamides kuxhomekeke kubunzima bazo beemolekyuli kunye noxinano lwetshaja, nto leyo evumela ukuba zenziwe ngokwezifiso kwizicelo ezithile. Ii-C-PAM zisebenza ngokukodwa ekunyangeni amanzi amdaka emizi-mveliso kunye nokukhuculwa kodaka ngenxa yokusebenza kwazo okuphezulu kwe-flocculation kunye neemfuno zedosi ephantsi.

I-Poly (diallyldimethylammonium chloride) (I-PolyDADMAC)

I-PolyDADMAC yi-flocculant ye-cationic esetyenziswa kakhulu eyaziwa ngokuba ne-charge density ephezulu kunye nokusebenza kakuhle kwiinkqubo zonyango lwamanzi. Le polymer isebenza kakhulu kwiinkqubo zokujiya kunye nokujiya, okwenza ukuba ibe lukhetho oludumileyo lokunyanga amanzi okusela, amanzi amdaka, kunye nenkunkuma yemizi-mveliso. I-PolyDADMAC isebenza kakuhle kunye nezinye ii-flocculant kunye nee-coagulants, iphucula inkqubo yonyango iyonke ngokubonelela ngendlela eqinileyo yokuhlanganisa nokususa iinxalenye.

IiPolyamines(PA)

Iipolyamines lolunye udidi lwee-cationic flocculants ezisetyenziswa kakhulu ekunyangweni kwamanzi. Ezi compounds, eziquka i-poly (dimethylamine-co-epichlorohydrin) kunye nezakhiwo ezifanayo, zibonisa uxinano olukhulu lwe-cationic charge, nto leyo eyenza ukuba zisebenze kakhulu ekuthomalaliseni amasuntswana atshajwe kakubi. Iipolyamines ziluncedo kakhulu ekucaciseni amanzi aluhlaza, ekususeni izinto eziphilayo, nasekunyangweni kwenkunkuma eyahlukeneyo yemizi-mveliso. Amandla azo okwenza ii-floc ezixineneyo akhokelela kwixesha lokuzinza ngokukhawuleza kunye nokucaca okuphuculweyo kwamanzi anyangiweyo.

Izicelo kunye neeNzuzo

Ii-flocculants ze-cationic zidlala indima ebalulekileyo kwiindlela ezahlukeneyo zokucoca amanzi, ukusuka kumanzi amdaka kamasipala kunye nokucocwa kwamanzi okusela ukuya kulawulo lwamanzi amdaka kwimizi-mveliso. Inzuzo yazo ephambili kukuba zikwazi ukuphelisa ngempumelelo amasuntswana atshajwe kakubi, nto leyo ekhokelela ekwakhekeni kwe-floc ngokukhawuleza nangokufanelekileyo. Oku kuphumela ekucaceni okuphuculweyo, ukuncipha kokungcola, kunye nokuphucula umgangatho wamanzi ngokubanzi. Ukongeza, ii-flocculants ze-cationic zihlala zisetyenziswa kunye nezinye iikhemikhali zonyango, ezifana nee-coagulants, ukuphucula inkqubo yonyango kunye nokufezekisa imigangatho yomgangatho wamanzi oyifunayo.

Ukusetyenziswa kwee-cationic flocculants kubalulekile kwiinkqubo zanamhlanje zonyango lwamanzi, kubonelela ngezisombululo ezisebenzayo nezithembekileyo zokuhlanganisa nokususa amasuntswana. IiPolyacrylamides, iipolyamines, iiPolyDADMAC zimele ezinye zezona flocculants zixhaphakileyo nezisebenzayo ze-cationic ezikhoyo namhlanje. Ukuguquguquka kwazo, ukusebenza kwazo kakuhle, kunye nokuzivumelanisa nezimo kuzenza zibe zizixhobo ezibalulekileyo ekuqinisekiseni ukufumaneka kwamanzi acocekileyo nakhuselekileyo kwiindlela ezahlukeneyo.

Kakade ke, ukhetho lwe-flocculant luxhomekeke kwindlela umsebenzisi ayisebenzisa ngayo, ukwakheka kwezinto, indawo ahlala kuyo, njl. Isikhokelo sokusetyenziswa kwemveliso kufuneka silandelwe.
