I-PolyDADMAC, egama layo elipheleleyo yi-polydimethyldiallylammonium chloride, i-polymer ye-cationic yamanzi e-soluble esetyenziswa ngokubanzi kwintsimi yonyango lwamanzi. Ngenxa yobuninzi bentlawulo ye-cationic kunye ne-solubility ephezulu yamanzi, i-PolyDADMAC i-coagulant esebenzayo inokususa ngokufanelekileyo i-turbidity, umbala kunye nokunye ukungcola emanzini. Nangona kunjalo, kwizicelo ezisebenzayo, ihlala isetyenziswa njengeflocculantngokudibanisa nezinye iicoagulants ukunyanga ilindle kwimizi-mveliso.
Iimpawu kunye neendlela zesenzo sePolyDADMAC
I-PolyDADMAC ibhengeza ngokukhawuleza kwaye idibanise amasuntswana e-colloidal ahlawuliswe kakubi kunye nezinto eziqinileyo ezimisiweyo emanzini ngenxa yoxinano oluphezulu lwentlawulo ye-cationic. Indlela yokusebenza kwayo isekelwe ikakhulu kumtsalane we-electrostatic, nto leyo ebangela ukuba la masuntswana amancinane adibane abe ngamasuntswana amakhulu, ukuze asuswe ngempumelelo ngexesha lemvula okanye iinkqubo zokuhluza.
Indlela ye-flocculation ye-PolyDADMAC
I-Flocculation yenye yamanyathelo kwinkqubo yokudibanisa. Ibhekisa kwinkqubo apho i
"Iintyatyambo ezincinci ze-alum" ezenziwe ngexesha lenkqubo yokudibanisa zenza iiflocs ezinamasuntswana amakhulu ngokusebenzisa i-adsorption, ukungathathi hlangothi kombane, ibhulorho kunye ne-net-capture.
Kumashishini okucoca amanzi, i-adsorption kunye ne-neutralization yombane zihlelwa njenge-coagulation, ngelixa i-bridging kunye ne-net-capture zihlelwa njenge-flocculation. Iikhemikhali ezihambelanayo zibizwa ngokuba yi-coagulants kunye ne-flocculants ngokulandelanayo.
Ngokuqhelekileyo kukholelwa ukuba i-PolyDADMAC ineendlela ezintathu zesenzo: i-adsorption, i-neutralization yombane kunye ne-bridging. Ezimbini zokuqala zezona ziphambili. Kungenxa yoko le nto iPolyDADMAC ihlelwa njenge-coagulants. Nangona kunjalo, uninzi lwabantu luthatha i-coagulation kunye ne-flocculation njengenkqubo efanayo, ke iPolyDADMAC ikwabizwa ngokuba yi-flocculant.
Kwiinkqubo zokunyanga amanzi, i-PolyDADMAC isetyenziswa kakhulu njenge-flocculant yokuphucula umgangatho wamanzi. Ngokukodwa, i-cationic quaternary ammonium salt group ye-PolyDADMAC inokuvelisa umtsalane we-electrostatic kunye ne-anionic suspended particles okanye i-colloidal particles emanzini, okubangela ukuba i-neutralization, yenze i-flocs yeengqungquthela ezinkulu kunye nokuzinza. Ezi flocs zihluzwa ngexesha le-sedimentation elandelayo okanye inkqubo yokucoca ukucoca umgangatho wamanzi.
Izinto eziluncedo zePolyDADMAC
Xa kuthelekiswa neeflocculants zemveli (i-alum, iPAC, njl.njl.), iPolyDADMAC inezi zinzuzo zilandelayo:
Ukusebenza kakuhle: I-PolyDADMAC inokususa ngokukhawuleza ukungcola emanzini kunye nokuphucula umgangatho wamanzi.
Kulula ukuyisebenzisa: Ukusetyenziswa kwayo kulula, yongeza nje phantsi kweemeko ezifanelekileyo.
Ukuzinza: I-PolyDADMAC inozinzo oluhle kwaye ayiphuli lula njenge-polyacrylamide.
Impembelelo enamandla ye-flocculation: Iqela letyuwa ye-cationic quaternary ammonium inika i-PDMDAAC isakhono esinamandla se-flocculation, ngaloo ndlela iphatha ngokufanelekileyo iimpawu ezahlukeneyo zamanzi;
Ukuxhathisa ityuwa elungileyo, ukuxhathisa kwe-asidi kunye ne-alkali: I-PDMDAAC ifanelekile kwiimeko ezintsonkothileyo zomgangatho wamanzi, kwaye isenomsebenzi ozinzileyo we-flocculation phantsi kwetyuwa ephezulu, i-acidic okanye i-alkaline;
Iindleko eziphantsi: I-PolyDADMAC inokusebenza kakuhle kwe-flocculation kunye ne-dosage ephantsi, enokunciphisa iindleko zokunyanga amanzi.
I-sludge ephantsi: I-PolyDADMAC ivelisa i-sludge encinci kune-coagulants ye-inorganic kunye ne-flocculants kwaye igcine iindleko ze-post-processing.
Idosi yePolyDADMAC kunye nezilumkiso
Xa usebenzisa i-PolyDADMAC, iinkqubo zokusebenza kufuneka zilandelwe ngokungqongqo ukuqinisekisa iziphumo ezilungileyo zonyango kwaye ugweme imiphumo enokwenzeka. Ngokuqhelekileyo, emva kokufaka i-flocculants efana ne-polyaluminium chloride, i-PolyDADMAC yongezwa ukufezekisa i-coagulation effect. Ukongeza, idosi kufuneka ilungiswe ngokufanelekileyo ngokwemigangatho yamanzi kunye neemfuno zonyango. Idosi efanelekileyo inokumiselwa ngovavanyo lwejagi.
Konke kwinto enye,PolyDADMACidlala indima ebalulekileyo kwintsimi yokucoca amanzi. Ukuqonda okunzulu kweempawu zayo kunye nezicelo kuya kunceda ukusebenzisa ngokufanelekileyo le mveliso ukuphucula umgangatho wamanzi kunye nokukhusela indalo.
