Ukungaqondani okuqhelekileyo xa ukhetha i-PAM

Polyacrylamide(I-PAM), njenge-polymer flocculant esetyenziswa ngokuqhelekileyo, isetyenziswa ngokubanzi kwiimeko ezahlukeneyo zokunyanga ilindle. Nangona kunjalo, abasebenzisi abaninzi baye bawela ekungaqondini okuthile ngexesha lokukhetha kunye nokusetyenziswa kwenkqubo. Eli nqaku lijonge ukuveza oku kungaqondani kunye nokunika ukuqonda okuchanekileyo kunye neengcebiso.

Ukungaqondi kakuhle 1: Okukhona ubunzima bemolekyuli, kokukhona buphezulu ukusebenza kakuhle kwe-flocculation.

Xa ukhetha i-polyacrylamide, abantu abaninzi bacinga ukuba imodeli enobunzima obukhulu bemolekyuli kufuneka ibe nokusebenza kakuhle kwe-flocculation. Kodwa eneneni, kukho amakhulu eemodeli zepolyacrylamide, ezilungele iimeko ezahlukeneyo zomgangatho wamanzi. Ubume bamanzi amdaka aveliswa ziifektri kumashishini ahlukeneyo ahlukile. Ixabiso le-pH kunye nokungcola okukhethekileyo kweempawu ezahlukeneyo zamanzi zahluke kakhulu. Zinokuba ne-asidi, i-alkaline, ingathathi hlangothi, okanye iqulethe ioli, i-organic matter, umbala, intlenga, njl. Ngoko ke, kunzima kuhlobo olulodwa lwe-polyacrylamide ukuhlangabezana nazo zonke iimfuno zokucocwa kwamanzi amdaka. Indlela echanekileyo kukuqala ngokukhetha imodeli ngokusebenzisa imifuniselo, kwaye emva koko uqhube iimvavanyo zoomatshini ukumisela idosi efanelekileyo yokufumana eyona mpembelelo inexabiso eliphezulu.

Ukungaqondi kakuhle i-2: Iphezulu i-concentration concentration, ingcono

Xa ulungiselela izisombululo ze-polyacrylamide, abasebenzisi abaninzi bakholelwa ukuba okukhona uxinaniso luphezulu, kokukhona iipropati ze-flocculation zingcono. Nangona kunjalo, le mbono ayilunganga. Enyanisweni, ukuxinwa koqwalaselo lwe-PAM kufuneka kumiselwe ngokwemiqathango ethile yogutyulo kunye neemeko zodaka. Ngokuqhelekileyo, izisombululo ze-PAM kunye ne-concentration ye-0.1% -0.3% zifanelekile kwi-flocculation kunye ne-sedimentation, ngelixa i-concentration ye-sludge kamasipala kunye ne-industrial dewatering yi-0.2% -0.5%. Xa kuninzi ukungcola kumanzi amdaka, ukuxinwa kwe-PAM kunokufuneka kwandiswe ngokufanelekileyo. Ke ngoko, uqwalaselo loqwalaselo olufanelekileyo kufuneka lugqitywe ngovavanyo ngaphambi kokusetyenziswa ukuqinisekisa eyona mpembelelo ilungileyo yokusetyenziswa.

Ukungaqondi kakuhle 3: Ukuba lide ixesha lokunyibilika kunye nokuvuselela, kungcono

I-Polyacrylamide yi-particle emhlophe ye-crystalline efuna ukuchithwa ngokupheleleyo ukufezekisa umphumo ongcono. Abasebenzisi abaninzi bacinga ukuba ixesha elide lokuchithwa kunye nokuvuselela, kungcono, kodwa enyanisweni oku akunjalo. Ukuba ixesha lokuvuselela lide kakhulu, liya kubangela ukuphuka kwenxalenye ye-PAM ye-molecular chain kwaye ichaphazele ukusebenza kwe-flocculation. Ngokuqhelekileyo, ixesha lokunyibilika kunye nokuvuselela akufanele libe ngaphantsi kwemizuzu engama-30 kwaye kufuneka landiswe ngokufanelekileyo xa ubushushu buphantsi ebusika. Ukuba ukuchithwa kunye nexesha lokuvuselela lifutshane kakhulu, i-PAM ayiyi kuchithwa ngokupheleleyo, okuya kubangela ukungakwazi ukwenza ngokufanelekileyo ukuhamba ngokukhawuleza emanzini amdaka. Ngoko ke, abasebenzisi kufuneka baqinisekise ukutshatyalaliswa okwaneleyo kunye nexesha lokuvuselela xa belisebenzisa ukuqinisekisa umphumo we-flocculation we-PAM.

Ukungaqondi kakuhle i-4: I-Ionicity / i-Ionic degree yodwa isiseko sokhetho

Njengenye yezalathi ezibalulekileyo ze-polyacrylamide, i-ionicity ibhekisa kwintlawulo ye-ionic embi kunye nelungileyo kunye nokuxinana kwayo kwentlawulo. Abantu abaninzi banikela ingqalelo kakhulu kwi-ionicity xa kuthengwa, becinga ukuba kokukhona kungcono. Kodwa eneneni, iqondo le-ioncity linxulumene nobukhulu bobunzima bemolekyuli. Okukhona i-ionicity iphezulu, incinci ubunzima be-molecular, kwaye ixabiso eliphezulu. Kwinkqubo yokukhetha, ngaphezu kwe-ionicity, ezinye izinto kufuneka ziqwalaselwe, ezifana neemeko ezithile zomgangatho wamanzi, iimfuno zempembelelo ye-flocculation, njl. Ngoko ke, imodeli ayikwazi ukukhethwa ngokusekelwe kuphela kwinqanaba le-ionization. Uvavanyo olongezelelweyo luyafuneka ukumisela imodeli efunekayo.

Njengeflocculant, i-polyacrylamide idlala indima ebalulekileyo kumashishini okucoca amanzi. Xa ufuna ukukhetha iinkcukacha ezikufanelayo, nceda uqhagamshelane nam.
