Indlela yokugweba impembelelo ye-flocculation ye-PAM kunye ne-PAC

Njenge-coagulant esetyenziswa ngokubanzi kwintsimi yonyango lwamanzi,PACibonisa ukuzinza kweekhemikhali okugqwesileyo kubushushu begumbi kwaye inoluhlu olubanzi lwe-pH lwesicelo. Oku kuvumela iPAC ukuba isabele ngokukhawuleza kwaye yenze iintyatyambo ze-alum xa kunyangwa iimpawu ezahlukeneyo zamanzi, ngaloo ndlela isusa ngokufanelekileyo izinto ezingcolisa amanzi. Kunyango lwamanzi amdaka amashishini, iPAC inempembelelo enkulu ekususweni kwezinto ezinobungozi ezifana ne-phosphorus, i-ammonia nitrogen, i-COD, i-BOD kunye ne-ion zetsimbi enzima. Oku kubangelwa ubukhulu becala kubuchule obuqinileyo bokuhlangana kwePAC, ekwaziyo ukujiya ezi zinto ziyingozi zibe ngamasuntswana amakhulu nge-adsorption kunye ne-coiling banding, iququzelele ukuhlaliswa okulandelayo kunye nokuhluzwa.

I-PAM: isixhobo esiyimfihlo sokwandisa i-flocculation

Isebenzisana nePAC, iPAM idlala indima ebaluleke kakhulu ekucoceni amanzi amdaka. Njenge-polymer flocculant, i-PAM inokuphucula umphumo we-flocculation ngokulungelelanisa ubunzima bayo be-molecular, ionicity kunye ne-ionic degree. I-PAM inokwenza i-flocs idibanise ngakumbi kwaye inyuse isantya se-sedimentation, ngaloo ndlela iphucula ukucaca kwamanzi. Ukuba i-dosage ye-PAM ayanelanga okanye igqithise, iiflocs zinokukhululeka, okukhokelela kumgangatho wamanzi amdaka.

Ukujonga impumelelo yePAC kunye nePAM ngokwemiqathango yefloc

Qaphela ubungakanani beeflocs: Ukuba iiflocs zincinci kodwa zisasazwa ngokulinganayo, oko kuthetha ukuba umlinganiselo wedosi ye-PAM kunye nePAC awulungelelaniswa. Ukuze kuphuculwe isiphumo, idosi yePAC kufuneka yonyuswe ngokufanelekileyo.

Vavanya isiphumo sentlenga: Ukuba izinto eziqinileyo ezinqunyanyisiweyo zikhulu kwaye intlenge isiphumo ilungile, kodwa umgangatho wamanzi ogqithisayo umdaka, oku kubonisa ukuba iPAC ayongezwa ngokwaneleyo okanye umlinganiselo wePAM awufanelekanga. Ngeli xesha, unokucinga ngokunyusa umthamo wePAC ngelixa ugcina ubungakanani bePAM ingatshintshwanga kwaye uqhubeke nokujonga isiphumo.

Qaphela i-morphology ye-flocs: Ukuba ii-flocs zinzima kodwa amanzi ane-turbid, i-dosage ye-PAM inokunyuswa ngokufanelekileyo; ukuba i-sediment incinci kwaye i-supernatant i-turbid, ibonisa ukuba i-dosage ye-PAM ayanelanga, kwaye umthamo wayo kufuneka unyuswe ngokufanelekileyo.

Ukubaluleka kovavanyo lwengqayi (ekwabizwa ngokuba yi-beaker experiment): Kuvavanyo lwengqayi, ukuba kufunyenwe isigqubuthelo eludongeni lwebeaker, oko kuthetha ukuba iPAM eninzi yongezwe. Ngoko ke, umthamo wayo kufuneka uncitshiswe ngokufanelekileyo.

Uvavanyo lokucaca: Xa izinto eziqinileyo ezimisiweyo zilungile okanye zirhabaxa, ukuba i-supernatant icace kakhulu, oko kuthetha ukuba umlinganiselo wedosi ye-PAM kunye ne-PAC usengqiqweni ngakumbi.

Ngamafutshane, ukuze kuphunyezwe eyona mpembelelo ibalaseleyo ye-flocculation, idosi yePAC kunye nePAM kufuneka ilawulwe ngononophelo kwaye ihlengahlengiswe. Ngokujonga kunye nokulinga, sinokugweba ngokuchanekileyo ngakumbi isiphumo sokusetyenziswa kwezi zimbini, ngaloo ndlela siphucula inkqubo yokucocwa kwelindle. Kwizicelo ezisebenzayo, kuyimfuneko ukuqwalasela ngokubanzi iimeko ezithile zomgangatho wamanzi, iimfuno zonyango, iiparamitha zezixhobo kunye nezinye izinto ukuze kuqulunqwe isicwangciso somntu wekhemikhali. Ukongezelela, ingqwalasela eyaneleyo kufuneka ihlawulwe kwindawo yokugcina, ukuthutha kunye nokulungiswa kwePAC kunye ne-PAM ukuqinisekisa ukusebenza kunye nokhuseleko lwamachiza.
