Indlela i-PAC ephucula ngayo ukusebenza kakuhle konyango lwamanzi kwimizi-mveliso

Kwicandelo lokunyanga amanzi kwimizi-mveliso, ukufuna izisombululo ezisebenzayo nezisebenzayo kubaluleke kakhulu. Iinkqubo zoshishino zihlala zivelisa amanzi amaninzi amdaka aqulethe izinto eziqinileyo ezixhonyiweyo, izinto eziphilayo, kunye nezinye izinto ezingcolisayo. Ukunyanga amanzi ngokufanelekileyo kubalulekile kungekuphela nje ekuthobeleni imithetho kodwa nakwimisebenzi ezinzileyo.I-poly aluminum chloride(PAC) idlala indima ebalulekileyo kule nkqubo ngokuncedisa ukujiya kunye nokuqunjelwa, amanyathelo abalulekileyo ekwahlukaniseni ukungcola emanzini.

I-poly aluminum chloride yikhemikhali yonyango lwamanzi esebenza ngeendlela ezininzi esebenza njenge-coagulant. Ii-coagulants zinceda ukungazinzi kwee-colloidal particles emanzini, zivumela ukuba zihlangane zibe zii-floc ezinkulu nezinzima ezinokususwa ngokulula nge-sedimentation okanye i-filtration. Ulwakhiwo olulodwa lwe-PAC, oluphawulwa yinethiwekhi eyinkimbinkimbi yee-polymers ze-aluminium oxyhydroxide, luyenza ikwazi ukwenza ii-floc ezinkulu nezixineneyo xa kuthelekiswa nee-coagulants eziqhelekileyo ezifana ne-aluminium sulfate.

Iingenelo eziphambili zokusebenzisa i-PAC kuNyango lwaManzi kwiMizi-mveliso

Ukuqina kwe-Coagulation kunye ne-Flocculation eNgcono

I-PAC ineempawu zokujiya eziphezulu xa ithelekiswa ne-coagulants zemveli ezifana ne-aluminium sulfate. Ulwakhiwo lwayo lwe-polymeric luvumela ukuhlanganiswa ngokukhawuleza kwamasuntswana amancinci, okwenza ii-flocs ezinkulu nezixineneyo. Oku kukhokelela ekufakweni kwenkunkuma kunye nokuhluzwa okusebenzayo ngakumbi, okubangela ukuba amanzi acace ngakumbi.

Ukusebenza kakuhle koLuhlu lwe-pH ebanzi

Enye yeenzuzo ezibalulekileyo ze-PAC kukukwazi kwayo ukusebenza ngokufanelekileyo kuluhlu olubanzi lwe-pH (5.0 ukuya kwi-9.0). Oku kuyenza ifaneleke ukunyanga iintlobo ezahlukeneyo zamanzi amdaka emizi-mveliso ngaphandle kokufuna uhlengahlengiso olukhulu lwe-pH, nto leyo egcina ixesha kunye neendleko zokusebenza.

Umthamo wodaka oncitshisiweyo

I-PAC ivelisa udaka oluncinci xa ithelekiswa nezinye izinto ezibangela ukuxinana kwamanzi, njengoko ifuna iidosi eziphantsi kunye neekhemikhali ezimbalwa ukuze kufezekiswe iziphumo ezifunwayo. Oku akunciphisi nje kuphela iindleko zokuphatha nokulahla udaka kodwa kunciphisa nomngcipheko wenkqubo yonyango kwindalo esingqongileyo.

Ukusebenza kakuhle kokuhluza okuphuculweyo

Ngokuvelisa ii-floc ezakhiwe kakuhle, i-PAC iphucula ukusebenza kweenkqubo zokucoca ezisezantsi. Amanzi acocekileyo aphuma kwinqanaba lokucoca andisa ubomi bezihluzo kwaye anciphise iimfuno zokugcinwa.

Ukusetyenziswa kweekhemikhali okuphantsi

Ukusebenza kakuhle kwe-PAC kuthetha ukuba kufuneka iikhemikhali ezimbalwa ukuze kufunyanwe iziphumo ezilungileyo. Oku kuthetha ukonga iindleko kunye nokunciphisa impembelelo enokubakho kwindalo esingqongileyo yeekhemikhali eziseleyo emanzini acociweyo.

Izicelo zeI-PAC kuNyango lwaManzi kwiMizi-mveliso

I-PAC isetyenziswa kwiindidi ezahlukeneyo zamashishini, kuquka:

Ishishini leempahla zelaphu:Ukususa iidayi kunye nokungcola okungokwemvelo emanzini amdaka.

Ukwenziwa kwePhepha:Ukuphucula ukucaca kunye nokususwa kombala emanzini enkqubo.

Ioyile kunye neGesi:Ukunyanga amanzi avelisiweyo kunye nokucoca amanzi amdaka.

Ukutya Neziselo:Ukuqinisekisa ukuthotyelwa kwemigangatho engqongqo yokukhupha abantu abaswelekileyo.

Njengoko amashishini ezama ukwamkela iindlela eziluhlaza, i-PAC ivela njengendlela ezinzileyo. Ukusebenza kwayo kakuhle kwiidosi eziphantsi, ukuveliswa kodaka olunciphileyo, kunye nokukwazi kwayo ukudibana ngokungenamthungo neenkqubo zonyango ezikhoyo kuhambelana neenjongo zokunciphisa ukusetyenziswa kwezixhobo kunye nokunciphisa inkunkuma.

Ngokufaka i-PAC kwiinkqubo zokunyanga amanzi, amashishini anokufezekisa ukungcola okucocekileyo, athobele imimiselo yokusingqongileyo, kwaye afake isandla kwiinkqubo zolawulo lwamanzi ezizinzileyo. Kumashishini afuna ukuphucula iinkqubo zawo zokunyanga amanzi, i-PAC inikezela ngesisombululo esithembekileyo nesiqinisekisiweyo sokuhlangabezana neemfuno zemingeni yanamhlanje yokucocwa kwamanzi.
