Ukuguqula ukucocwa kwamanzi amdaka: iiPolyamines njengeSitshixo kwizisombululo eziZinzileyo nezisebenzayo

Ukucocwa kwamanzi amdaka yinkqubo ebalulekileyo yokuqinisekisa amanzi acocekileyo nakhuselekileyo ukuze asetyenziswe ngabantu kunye nokukhusela okusingqongileyo.Iindlela zemveli zokunyanga amanzi amdaka zixhomekeke ekusebenziseniimichiza coagulants, njenge-aluminiyam kunye neetyuwa zentsimbi, ukususa ukungcola emanzini.Nangona kunjalo, eziiikhemikhali zokunyanga amanzi kwimizi-mvelisozibiza kakhulu, zifuna umbane kakhulu, kwaye zinokuba neempembelelo ezimbi zokusingqongileyo.

Ngethamsanqa, isisombululo esitsha siye savela kwintsimi yokucoca amanzi amdaka -iipolyamines(PA).I-Polyamines liqela leekhompawundi eziphilayo ezifumaneka ngokwemvelo kwiiseli eziphilayo kwaye zineempawu ezizodwa ezenza ukuba zisebenze kakhulu kunyango lwamanzi amdaka.Ukusetyenziswa kweepolyamines kuguqula intsimi yokucoca amanzi amdaka kwaye inikezela ngesisombululo esizinzileyo nesisebenzayo kwimingeni yongcoliseko lwamanzi kunye nokunqongophala.

I-China ngomnye wabathengi abakhulu beekhemikhali zokucoca amanzi kwihlabathi, kunye nemfuno ekhula ngokukhawuleza yezisombululo zokucocwa kwamanzi amdaka asebenzayo kwaye afikelelekayo.Ukusetyenziswa kwe-polyamines kwishishini lokucocwa kwamanzi amdaka laseTshayina lifumana amandla ngenxa yokusebenza kwazo okuphezulu kunye nokusebenza kakuhle kweendleko xa kuthelekiswa neekhemikhali zemveli.

Iipolyamines zineenzuzo ezininzi ngaphezu kweekhemikhali zokucoca amanzi emveli.Enye yeenzuzo eziphambili kukunxulumana kwabo okuphezulu kungcoliseko olwahlukeneyo olufumaneka kumanzi amdaka, njengesinyithi esinzima, idayi, kunye neekhompawundi eziphilayo.Iipolyamines zinokujija ngokufanelekileyo kwaye zihambise ezi zingcolisi, okukhokelela ekususweni kwazo ngokulula emanzini.Le nkqubo iphucula ngokubonakalayo ukusebenza kakuhle kwenkqubo yokucocwa kwamanzi amdaka, okukhokelela kumgangatho ongcono wamanzi amdaka.

Enye inzuzo yeepolyamines yimfuno yabo yedosi ephantsi.Iipolyamines zinokufikelela kwinqanaba elifanayo lokususa ungcoliseko njengemichiza yemveli ngamanani amancinci, okukhokelela ekongeni kweendleko ezinkulu zezityalo zokucocwa kwamanzi amdaka.Ngaphezu koko, ukusetyenziswa kwe-polyamines kunokunciphisa inani le-sludge eyenziwa ngexesha lonyango, elinokunciphisa ngakumbi iindleko zokusebenza.

Ekugqibeleni, ukusetyenziswa kwePA ekucocweni kwamanzi amdaka kuguqula ibala lokucocwa kwelindle kwaye linikezela ngesisombululo esizinzileyo nesisebenzayo kwimingeni yongcoliseko lwamanzi kunye nokunqaba.Ngemfuno ekhulayo yezisombululo zokucocwa kwamanzi amdaka asebenzayo kwaye afikelelekayo e-China, ukusetyenziswa kwe-polyamines kushishino lokucocwa kwamanzi amdaka kulindeleke ukuba kwandiswe kwiminyaka ezayo, ukubonelela ngendawo ecocekileyo nekhuselekileyo kubo bonke.
