I-PolyDADMAC njenge-organic coagulant kunye ne-flocculant: isixhobo esinamandla sokunyanga amanzi amdaka emizi-mveliso

Ngenxa yophuhliso olukhawulezileyo lwemizi-mveliso, ukukhutshwa kwamanzi amdaka kwimizi-mveliso kuye kwanda minyaka le, nto leyo ebeka umngcipheko omkhulu kwindalo esingqongileyo. Ukuze sikhusele indalo esingqongileyo, kufuneka sithathe amanyathelo asebenzayo okunyanga la manzi amdaka. Njenge-i-organic coagulant, iPolyDADMAC kancinci kancinci iba sisisombululo esithandwayo sokunyanga amanzi amdaka emizi-mveliso.

Kutheni kufuneka kuphathwe amanzi amdaka emizi-mveliso?

Iingozi zamanzi amdaka emizi-mveliso azinakubethwa ngoyaba. Amanzi amdaka aqulethe inani elikhulu lee-ion zesinyithi ezinzima, iikhemikhali eziyingozi, iioyile, njl. Ezi zinto ziyingozi kakhulu kwizidalwa zasemanzini nakubantu. Ukukhutshwa kwamanzi amdaka anganyangwanga ixesha elide kuya kukhokelela kungcoliseko lwamanzi, umonakalo kwindalo, kunye nezifo zabantu.

Njengoko imveliso yemizi-mveliso iqhubeka nokwanda, amanzi amaninzi amdaka akhutshwa ngqo kwindalo esingqongileyo ngaphandle kokunyangwa, nto leyo eyonakalisa kakhulu ulungelelwaniso lwendalo kwaye ibeka impilo yabantu esichengeni. Ke ngoko, kufuneka sithathe amanyathelo okunyanga amanzi amdaka emizi-mveliso ukuze sinciphise impembelelo yawo embi kwindalo esingqongileyo.

Kutheni ukhethaI-PolyDADMACukunyanga amanzi amdaka emizi-mveliso?

Ukujongana neengozi zamanzi amdaka emizi-mveliso, iindlela zonyango ezisetyenziswa rhoqo ziquka ukufunxa i-alum okanye i-PAC. Nangona kunjalo, ezi ndlela zemveli zihlala zineengxaki ezifana nomthamo ophezulu wodaka, imisebenzi enzima, kunye neendleko eziphezulu. Ke ngoko, kufuneka sifumane indlela yonyango esebenza kakuhle, engabizi kakhulu, neyongamela ukusingqongileyo. Njenge-organic coagulant, i-PolyDADMAC ineempawu ezibalaseleyo zokuqunjelwa kunye nokuxinana kwaye inokususa ngokukhawuleza nangokufanelekileyo izinto eziqinileyo ezixhonyiweyo (ezihlala ziqulathe ii-ion zesinyithi esinzima kunye neekhemikhali eziyingozi) emanzini amdaka. Xa kuthelekiswa neendlela zemveli zokucubungula, i-PolyDADMAC ineengenelo zokusebenza lula, ukusebenza kakuhle kokucubungula, umthamo ophantsi wodaka, kunye neendleko eziphantsi. I-PolyDADMAC ikwasetyenziswa njengearhente yokukhupha amanzi odaka ukunciphisa umxholo wamanzi odaka olubangelwa zezinye iinkqubo zoshishino.

I-PolyDADMAC iwaphatha njani amanzi amdaka emizi-mveliso?

Okokuqala, yongeza isisombululo esixutyiweyo sePolyDADMAC emanzini amdaka ngokwemilinganiselo ethile uze usixube kakuhle ngokuxubha. Phantsi kwesenzo se-coagulant, izinto eziqinileyo ezixhonyiweyo emanzini amdaka ziya kuhlangana ngokukhawuleza zenze ii-particle flocs ezinkulu. Emva koko, ngamanyathelo onyango alandelayo anje ngokuthungwa okanye ukuhluzwa, i-floc iyahlulwa kumanzi amdaka ukuze kufezekiswe injongo yokucoca amanzi amdaka.

Xa usebenzisa iPolyDADMAC ukunyanga amanzi amdaka emizi-mveliso, kufuneka unikele ingqalelo kule mibandela ilandelayo. Okokuqala, kufuneka ukhethe umthengisi onomgangatho othembekileyo ukuqinisekisa ukuba i-coagulant ethengiweyo ikumgangatho ofanelekileyo. Okwesibini, ngokwendalo kunye noxinzelelo lwamanzi amdaka, umthamo we-coagulant kufuneka ukhethwe ngokufanelekileyo ukuze kuthintelwe ukugqithiswa okanye unyango olunganelanga olukhokelela kwiziphumo zonyango ezingalunganga. Kwangaxeshanye, umgangatho wamanzi amdaka acociweyo kufuneka uhlolwe rhoqo ukuqinisekisa ukuba imigangatho yokukhupha iyafezekiswa. Ukongeza, abaqhubi kufuneka bafumane uqeqesho lobungcali kwaye baqhelane neempawu kunye nokusetyenziswa kwe-coagulants kunye namanyathelo okukhusela ukuqinisekisa ukhuseleko kunye nokuzinza kwenkqubo yonyango.

Ngamafutshane, iPolyDADMAC, njenge-coagulant esebenzayo neyonga imali, ineengenelo ezibalulekileyo ekuphatheni amanzi amdaka emizi-mveliso. Ngokusebenzisa i-PolyDADMAC ngendlela eyiyo, singayinciphisa ngempumelelo ingozi yamanzi amdaka emizi-mveliso kwindalo esingqongileyo kwaye sikhusele ulungelelwaniso lwendalo kunye nempilo yabantu. Kwixesha elizayo, ngokuphuculwa okuqhubekayo kolwazi lwendalo esingqongileyo kunye nophuhliso lwetekhnoloji, iPolyDADMAC iya kudlala indima ebaluleke ngakumbi kwicandelo lokunyanga amanzi amdaka emizi-mveliso.
