Indlela yokugweba isiphumo se-flocculation se-PAM kunye ne-PAC

Njenge-coagulant esetyenziswa kakhulu kwicandelo lokunyanga amanzi, i-PAC ibonisa uzinzo oluhle kakhulu lweekhemikhali kubushushu begumbi kwaye inoluhlu olubanzi lwe-pH yokusetyenziswa. Oku kuvumela i-PAC ukuba iphendule ngokukhawuleza kwaye yenze iintyatyambo ze-alum xa iphatha iimpawu ezahlukeneyo zamanzi, ngaloo ndlela isusa ngempumelelo ukungcola emanzini. Kunyango lwamanzi amdaka emizi-mveliso, i-PAC inefuthe elikhulu ekususweni kwezinto ezinobungozi ezifana ne-phosphorus, i-ammonia nitrogen, i-COD, i-BOD kunye nee-ion zesinyithi esinzima. Oku kungenxa kakhulu yamandla okujiya kwe-PAC, ekwaziyo ukujiya ezi zinto zinobungozi zibe ngamasuntswana amakhulu ngokufaka i-adsorption kunye ne-coiling banding, okwenza kube lula ukuhlala kunye nokuhluza okulandelayo.

I-PAM: isixhobo esiyimfihlo sokwenza ngcono i-flocculation 

Ngokusebenzisana ne-PAC, i-PAM idlala indima ebalulekileyo ekunyangweni kwamanzi amdaka. Njenge-polymer flocculant, i-PAM inokuphucula isiphumo se-flocculation ngokulungelelanisa ubunzima bayo be-molecular, i-ionicity kunye ne-ionic degree. I-PAM ingenza ii-floc zibe ncinci ngakumbi kwaye yonyuse isantya se-sedimentation, ngaloo ndlela iphucula ukucaca kwamanzi. Ukuba idosi ye-PAM ayanelanga okanye igqithisile, ii-floc zinokukhululeka, nto leyo ekhokelela kumgangatho wamanzi omdaka.

Ukugweba ukusebenza kwe-PAC kunye ne-PAM ngokweemeko ze-floc

Jonga ubungakanani bee-flocs: Ukuba ii-flocs zincinci kodwa zisasazwe ngokulinganayo, oko kuthetha ukuba umlinganiselo wedosi ye-PAM kunye ne-PAC awulungelelaniswanga. Ukuze kuphuculwe isiphumo, umthamo we-PAC kufuneka wonyuswe ngokufanelekileyo.

Vavanya isiphumo sokugalela: Ukuba izinto eziqinileyo ezixhonyiweyo zikhulu kwaye isiphumo sokugalela silungile, kodwa i-supernatant yomgangatho wamanzi imdaka, oku kubonisa ukuba i-PAC ayongezwanga ngokwaneleyo okanye umlinganiselo we-PAM awufanelekanga. Ngeli xesha, ungacinga ngokunyusa umthamo we-PAC ngelixa ugcina umlinganiselo we-PAM ungatshintshi kwaye uqhubeke nokujonga isiphumo.

Qaphela indlela ezimile ngayo ii-flocs: Ukuba ii-flocs zijiyile kodwa amanzi amdaka, umthamo we-PAM unokwandiswa ngokufanelekileyo; ukuba i-sediment incinci kwaye i-supernatant imdaka, oko kubonisa ukuba umthamo we-PAM awonelanga, kwaye umthamo wayo kufuneka unyuswe ngokufanelekileyo.

Ukubaluleka kovavanyo lwebhotile (olubizwa ngokuba luvavanyo lwebhotile): Kuvavanyo lwebhotile, ukuba kufunyenwe inkunkuma eludongeni lwebhotile, oko kuthetha ukuba kongezwe i-PAM eninzi kakhulu. Ke ngoko, idosi yayo kufuneka incitshiswe ngokufanelekileyo.

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

Ngamafutshane, ukuze kufezekiswe isiphumo esihle kakhulu sokuqunjelwa, idosi ye-PAC kunye ne-PAM kufuneka ilawulwe ngononophelo kwaye ilungiswe. Ngokujonga kunye novavanyo, sinokugweba ngokuchanekileyo isiphumo sokusetyenziswa kwezi zimbini, ngaloo ndlela siphucule inkqubo yokucocwa kwamanzi amdaka. Kwizicelo ezisebenzayo, kuyimfuneko ukuqwalasela ngokupheleleyo iimeko ezithile zomgangatho wamanzi, iimfuno zonyango, iiparameter zezixhobo kunye nezinye izinto ukuze kwenziwe isicwangciso sokulinganisa iikhemikhali ezenzelwe wena. Ukongeza, kufuneka kunikwe ingqalelo eyaneleyo ekugcineni, ekuthuthweni nasekulungisweni kwe-PAC kunye ne-PAM ukuqinisekisa ukusebenza kakuhle kunye nokhuseleko lwamayeza.
