Bakeng sa ho qhala kapa ho sebelisa hape Mokelikeli ka mor'a Phekolo, mefuta e fapaneng ea Lik'hemik'hale e lokela ho sebelisoa ts'ebetsong ea Phekolo ea Likhoerekhoere.Kajeno,PAM (Polyacrylamide) barekisie tla u bolella ka li-flocculants:
Flocculant: Ka linako tse ling hape e bitsoa coagulant, e ka sebelisoa e le mokhoa oa ho matlafatsa karohano ea metsi a tiileng, 'me e ka sebelisoa ka tanka ea ho lokisa ea mantlha, tanka ea ho lokisa ea bobeli, tanka ea flotation, phekolo ea thuto e phahameng kapa phekolo e tsoetseng pele le lihokelo tse ling tsa ts'ebetso.
Li-flocculants li sebelisoa e le mokhoa oa ho matlafatsa karohano e tiileng-metsi tšimong ea phekolo ea likhoerekhoere.Li ka sebelisoa ho matlafatsa sedimentation ea mantlha ea likhoerekhoere, kalafo ea flotation le sedimentation ea bobeli ka mor'a ts'ebetso ea seretse, hape e ka sebelisoa bakeng sa kalafo ea thuto e phahameng kapa kalafo e tsoetseng pele ea likhoerekhoere.Ha e sebelisoa bakeng sa boemo pele ho felloa ke metsi a litšila tse feteletseng, li-flocculants le li-coagulant li fetoha li-conditioner tsa sludge kapa li-dehydrating agents.
Ha u sebelisa li-flocculants tsa setso, mokhoa oa ho eketsa lithuso tsa coagulant o ka sebelisoa ho ntlafatsa phello ea flocculation.Ka mohlala, ho sebelisa activated silicic acid e le coagulant aid bakeng sa inorganic flocculants tse kang ferrous sulfate le aluminium sulfate le ho li eketsa ka tatellano ho ka finyella flocculation e ntle.Ka hona, ho ea ka mantsoe a layman, IPF ea inorganic polymer flocculant e hlile e lokiselitsoe ka ho kopanya thuso ea coagulant le flocculant ebe e kopantsoe hammoho ho nolofatsa ts'ebetso ea mosebelisi.
Kalafo ea coagulation e atisa ho behoa ka pel'a setsi sa karohano ea metsi a tiileng, 'me e kopantsoe le sebaka sa karohano, e ka khona ho tlosa lintho tse tiileng tse emisitsoeng le lintho tsa colloidal tse nang le boholo ba karolo ea 1nm ho ea ho 100μm metsing a tala, ho fokotsa metsi a litšila le CODCr, 'me e ka sebelisoa ho lokisa mekhoa ea likhoerekhoere esale pele.Kalafo, phekolo e tsoetseng pele, e ka boela ea sebelisoa bakeng sa phekolo ea sludge e setseng.Phekolo ea coagulation e ka boela ea tlosa likokoana-hloko le libaktheria tsa pathogenic ka katleho metsing, 'me ea tlosa oli ea emulsified, chroma, li-ion tsa tšepe tse boima le litšila tse ling tsa likhoerekhoere.Sekgahla sa ho tloswa ha phosphorus e ka hara dikgwerekgwere e ka ba hodimo ho 90% ha coagulation sedimentation e sebediswa ho phekola phosphorus.~95%, ke mokhoa o theko e tlaase le o sebetsang ka ho fetisisa oa ho tlosa phosphorus.
Ts'ebetsong ea ho hloekisa likhoerekhoere, lisebelisoa tse ling li tla sebelisoa.Kajeno, thePAM Moetsie hlahisitse e le nngwe feela ya tsona.O ntse o utlwisisa?Ela hloko Yuncang 'me u arabele tsebo e eketsehileng ea ho hloekisa likhoerekhoere bakeng sa hau!
