Ziziphi iiflocculants eziqhelekileyo ze-cationic?

Ukucocwa kwamanzi yinxalenye ebalulekileyo yolawulo lwendalo esingqongileyo, ukuqinisekisa ukuba amanzi akhuselekile ukuba angasetyenziswa kunye nokusetyenziswa kwimizi-mveliso. Enye yezinto eziphambili kule nkqubo kukusetyenziswa kweeflocculants—imichiza ekhuthaza ukudityaniswa kwamasuntswana ajingayo abe ngamaqela amakhulu, anokususwa ngokulula ngakumbi emanzini. Phakathi kweentlobo ezahlukeneyo ze-flocculants, ii-cationic flocculants zisebenza ngokukodwa ngenxa yentlawulo yabo efanelekileyo, edibanisa ngamandla kunye neengqungquthela ezithintekayo ezixhaphakileyo ezifumaneka kumanzi amdaka. Eli nqaku liphonononga iiflocculants ze-cationic eziqhelekileyo ezisetyenziselwa unyango lwamanzi kunye nezicelo zabo.

Iipolyacrylamides zeCationic(CPAM)

I-Cationic Polyacrylamides, ziphakathi kwezona flocculants zisetyenziswa kakhulu kushishino lokucoca amanzi. Kubasebenzisi abaninzi, iCPAM lukhetho lwabo olungcono. Ezi polymers ziquka i-acrylamide subunits, enokuthi ilungiselelwe ukubandakanya amaqela asebenzayo e-cationic. Ukuguquguquka kweCationic polyacrylamides ilele kubunzima bazo obuhlengahlengiswayo bemolekyuli kunye nokuxinana kwentlawulo, okubavumela ukuba benzelwe usetyenziso oluthile. Ii-C-PAMs zisebenza ngokukodwa ekunyangeni amanzi amdaka akwimizi-mveliso kunye nokucocwa kodaka ngenxa yokusebenza kakuhle kwazo kunye neemfuneko zedosi ephantsi.

Poly(diallyldimethylammonium chloride) (PolyDADMAC)

I-PolyDADMAC isetyenziswa ngokubanzi i-cationic flocculant eyaziwayo ngokuxinwa kwayo okuphezulu kunye nokusebenza kakuhle kwiinkqubo zokunyanga amanzi. Le polymer isebenza ngokukodwa kwiinkqubo zokudibanisa kunye ne-flocculation, iyenza ibe lukhetho oludumileyo lokunyanga amanzi okusela, amanzi amdaka, kunye nokungcola kwimizi-mveliso. I-PolyDADMAC isebenza kakuhle ngokubambisana namanye ama-flocculants kunye ne-coagulants, ukuphucula inkqubo yonyango ngokubanzi ngokubonelela ngendlela eqinile yokudibanisa amaqhekeza kunye nokususwa.

Iipolyamines(PA)

I-Polyamines lolunye udidi lwe-cationic flocculants olusetyenziswa ngokuqhelekileyo kunyango lwamanzi. Ezi zixhobo, ezibandakanya i-poly (dimethylamine-co-epichlorohydrin) kunye nezakhiwo ezifanayo, zibonisa ukuxinwa kwentlawulo ye-cationic eqinile, ezenza zisebenze kakhulu ekunciphiseni amasuntswana ahlawuliswa kakubi. I-Polyamines ibaluleke kakhulu ekucaciseni amanzi akrwada, ukususwa kwezinto eziphilayo, kunye nokunyangwa kwamanzi ahlukeneyo amashishini. Ukukwazi kwabo ukwenza iiflocs ezixineneyo kubangela amaxesha okuzinzisa ngokukhawuleza kunye nokucaca okuphuculweyo kwamanzi acociweyo.

Usetyenziso kunye nezinto eziluncedo

I-Cationic flocculants idlala indima ebalulekileyo kuluhlu olubanzi lwezicelo zokucocwa kwamanzi, ukusuka kumanzi amdaka kamasipala kunye nokucocwa kwamanzi okusela ukuya kulawulo lwamanzi amdaka kwimizi-mveliso. Inzuzo yabo ephambili ixhomekeke ekukwazini kwabo ukungathathi hlangothi ngokufanelekileyo amasuntswana ahlawuliswa kakubi, okukhokelela ekubunjweni kwefloc ngokukhawuleza nangokufanelekileyo. Oku kukhokelela ekucaceni okuphuculiweyo, ukuthotywa kwe-turbidity, kunye nokuphucula umgangatho wamanzi ngokubanzi. Ukongeza, iiflocculants ze-cationic zihlala zisetyenziswa ngokudityaniswa nezinye iikhemikhali zonyango, ezinje nge-coagulants, ukwandisa inkqubo yonyango kunye nokufikelela kwimigangatho efunwayo yomgangatho wamanzi.

Ukusetyenziswa kweeflocculants ze-cationic kuyinxalenye yeenkqubo zanamhlanje zokunyanga amanzi, ukunika izisombululo ezisebenzayo nezithembekileyo zokudityaniswa kwamasuntswana kunye nokususwa. I-Polyacrylamides, i-polyamines, i-PolyDADMAC imele ezinye zezona ziqhelekileyo kwaye zisebenzayo ze-cationic flocculants ezikhoyo namhlanje. Ukuguquguquka kwazo, ukusebenza kakuhle, kunye nokuguquguquka kwazo kuzenza zibe zizixhobo eziyimfuneko ekuqinisekiseni ukufumaneka kwamanzi acocekileyo nakhuselekileyo okusetyenziswa ngeendlela ezahlukeneyo.

Ngokuqinisekileyo, ukhetho lwe-flocculant luxhomekeke kwimikhwa yokusetyenziswa komsebenzisi, ukwakhiwa kwezinto, indawo, njl njl. Isikhokelo sokusetyenziswa kwemveliso kufuneka silandelwe.
