I-PolyDADMAC, egama layo lipheleleyo yi-polydimethyldiallylammonium chloride, yi-polymer enyibilikayo emanzini e-cationic esetyenziswa kakhulu kwicandelo lokunyanga amanzi. Ngenxa yobuninzi bayo obukhethekileyo be-cationic charge kunye nokunyibilika kwamanzi okuphezulu, i-PolyDADMAC yi-coagulant esebenzayo enokususa ngempumelelo ukungcola, umbala kunye nokunye ukungcola emanzini. Nangona kunjalo, kwizicelo ezisebenzayo, idla ngokusetyenziswa njenge-i-flocculantxa idibene nezinye izinto ezibangela ukuxinana kwamanzi ukuze kulungiswe amanzi amdaka emizi-mveliso.
Iimpawu kunye nendlela yokusebenza kwePolyDADMAC
I-PolyDADMAC ifunxa ngokukhawuleza kwaye ihlanganise amasuntswana e-colloidal atshajwe kakubi kunye nezinto eziqinileyo ezixhonyiweyo emanzini ngenxa yobuninzi bayo be-cationic charge. Indlela esebenza ngayo isekelwe ikakhulu ekutsaleni kwe-electrostatic, okubangela ukuba la masuntswana mancinci ahlangane abe ngamasuntswana amakhulu, ukuze asuswe ngempumelelo ngexesha leenkqubo ezilandelayo zokuna kwemvula okanye zokuhluza.
Indlela yokudibanisa i-PolyDADMAC
Ukuqunjelwa linye lamanyathelo kwinkqubo yokujiya kwamalungu omzimba. Libhekisa kwinkqubo apho
"Iintyatyambo ezincinci ze-alum" ezenziwe ngexesha lenkqubo yokujiya zenza ii-flocs ezinamasuntswana amakhulu ngokufunxa, ukuthomalalisa umbane, ukubopha kunye nokubamba i-net.
Kwishishini lokucoca amanzi, ukufunxa amanzi kunye nokungashukumi kombane kuhlelwa njenge-coagulation, ngelixa i-bridging kunye ne-net-capture kuhlelwa njenge-flocculation. Iikhemikhali ezifanayo zibizwa ngokuba yi-coagulants kunye ne-flocculants ngokwahlukeneyo.
Ngokwesiqhelo kukholelwa ukuba iPolyDADMAC ineendlela ezintathu zokusebenza: ukufunxa, ukunganyamezeli kombane kunye nokubopha. Ezokuqala ezimbini zezona ziphambili. Yiyo loo nto iPolyDADMAC ihlelwa njengee-coagulants. Nangona kunjalo, uninzi lwabantu lubona ukujiya kunye ne-flocculation njengenkqubo efanayo, ngoko ke iPolyDADMAC ikwabizwa ngokuba yi-flocculant.
Kwiinkqubo zokunyanga amanzi, iPolyDADMAC isetyenziswa kakhulu njenge-flocculant ukuphucula umgangatho wamanzi. Ngokukodwa, iqela letyuwa ye-cationic quaternary ammonium yePolyDADMAC linokuvelisa umtsalane we-electrostatic ngee-anionic suspended particles okanye ii-colloidal particles emanzini, nto leyo ebangela ukuba i-neutralization, yenze ii-flocs zee-particles ezinkulu kwaye zihlale phantsi. Ezi flocs ziyahlolwa ngexesha lenkqubo elandelayo yokutsalwa okanye yokuhluzwa ukuze kuhlanjululwe umgangatho wamanzi.
Iingenelo zePolyDADMAC
Xa kuthelekiswa nee-flocculants zendabuko (i-alum, i-PAC, njl.njl.), i-PolyDADMAC ineenzuzo ezibalulekileyo ezilandelayo:
Isebenza kakuhle: I-PolyDADMAC inokususa ukungcola emanzini ngokukhawuleza kwaye iphucule umgangatho wamanzi.
Kulula ukuyisebenzisa: Ukusetyenziswa kwayo kulula, yongeza nje phantsi kweemeko ezifanelekileyo.
Ukuzinza: I-PolyDADMAC izinzile kakuhle kwaye ayiqhekeki lula njenge-polyacrylamide.
Isiphumo esinamandla sokuqunjelwa: Iqela letyuwa ye-cationic quaternary ammonium linika i-PDMDAAC amandla okuqunjelwa aqinileyo, ngaloo ndlela iphatha ngempumelelo iimpawu ezahlukeneyo zamanzi;
Ukumelana kakuhle netyuwa, ukumelana ne-asidi kunye ne-alkali: I-PDMDAAC ifanelekile kwiimeko ezinzima zomgangatho wamanzi, kwaye isenamandla okushukuma okuzinzileyo phantsi kweemeko zetyuwa ephezulu, i-asidi okanye i-alkali;
Ixabiso eliphantsi: I-PolyDADMAC inamandla aphezulu okuhambahamba kunye nedosi ephantsi, enokunciphisa iindleko zokunyanga amanzi.
Udaka oluphantsi: I-PolyDADMAC ivelisa udaka oluncinci kune-inorganic coagulants kunye ne-flocculants kwaye igcina iindleko zokucubungula emva kokusetyenziswa.
Idosi yePolyDADMAC kunye namanyathelo okhuseleko
Xa usebenzisa iPolyDADMAC, iinkqubo zokusebenza kufuneka zilandelwe ngokungqongqo ukuqinisekisa iziphumo zonyango ezilungileyo kwaye kuthintelwe iziphumo ebezingalindelekanga. Ngokwesiqhelo, emva kokongeza ii-flocculants ezifana ne-polyaluminium chloride, iPolyDADMAC yongezwa ukuze kufezekiswe isiphumo esihle kakhulu sokujiya. Ukongeza, idosi kufuneka ilungiswe ngokufanelekileyo ngokwemigangatho yamanzi kunye neemfuno zonyango. Idosi efanelekileyo inokumiselwa ngovavanyo lweejagi.
Konke kwinto enye,I-PolyDADMACidlala indima ebalulekileyo kwicandelo lokunyanga amanzi. Ukuqonda nzulu iimpawu zayo kunye nokusetyenziswa kwayo kuya kunceda ekusebenziseni le mveliso ngempumelelo ukuphucula umgangatho wamanzi nokukhusela okusingqongileyo.
