Mohato oa bohlokoa ts'ebetsong ea ho hloekisa metsi a litšila ke ho kopanya le ho lokisoa ha lintho tse tiileng tse emisitsoeng, e leng mokhoa o itšetlehileng haholo ka lik'hemik'hale tse bitsoang flocculants. Tabeng ena, li-polymers li phetha karolo ea bohlokoa, kahoo PAM, polyamines.li-flocculants tsa polymer, tšebeliso ea li-polymers e le li-flocculants ho hloekisa metsi a litšila, le mesebetsi e ka morao ho tsona.
Li-polymer flocculants tse sebelisoang hangata ke life?
Li-polymer flocculants tse sebelisoang ka tloaelo li kenyelletsa li-polymers tsa cationic, li-polymer tsa anionic le li-polymers tsa nonionic. Li-polymer tsena li ka fumanoa ka mekhoa e fapaneng ea maiketsetso mme li na le meaho e fapaneng ea cationic le ea makala. Lits'ebetsong tse sebetsang, hoa hlokahala ho khetha li-polymer flocculants tse loketseng ho latela maemo a khethehileng a metsi a litšila ho fumana phello e ntle ea kalafo. PAM, polyDADMAC, e sebelisoa haholo ho hloekisa metsi a litšila a indasteri. Polyacrylamide ke flocculant e sebelisoang ka ho fetisisa lefatšeng. Li-polymer tsena tse qhibilihang ka metsi li entsoe 'me li ka etsoa ka mokhoa o ikhethileng bakeng sa lits'ebetso tse ikhethileng ka litekanyo tse fapaneng tsa limolek'hule, li-viscosities, likhato tse fapaneng tsa tefiso, mefuta e fapaneng e kang likaroloana, li-emulsions, joalo-joalo PolyDADMAC e sebelisoa haholo metsing a pompo, ho phalla ha metsi a tala, sludge. dehydration, indasteri ea pampiri le indasteri ea khatiso le dae.
Tšebeliso ea li-flocculants ho hloekisa metsi a litšila
Sepheo se seholo sa ho hloekisa metsi a litšila ke ho tlosa lintho tse silafatsang tse kang lintho tse tiileng tse emisitsoeng, lintho tse phelang tse qhibilihisitsoeng le likaroloana tsa colloidal tse tsoang metsing ho ntlafatsa boleng ba metsi. Ts'ebetsong ena, li-flocculants li phetha karolo ea bohlokoa. Ka ho sebelisa li-flocculants, likaroloana tse nyenyane le lintho tse nyenyane tse ka metsing li ka etsa hore li kopane hore e be lihlopha tse khōloanyane, tse ka ntšoang habonolo ka ho qhibiliha kapa ho sefa. Sena se ke ke sa ntlafatsa boleng ba metsi feela, empa hape se ka ntlafatsa ts'ebetso ea kalafo le ho fokotsa litšenyehelo tsa kalafo.
Ke hobane'ng ha li-polymers li ka etsa li-flocculants?
Li-polymers li ka sebelisoa e le li-flocculants haholo-holo ka lebaka la boima ba tsona bo phahameng ba limolek'hule le sebopeho sa makala a mangata. Lintho tsena li lumella polymer hore e iketsetse hantle holim'a lintho tse nyenyane, ho etsa lihlopha tse kholo tse ka lulang kapele. Ho phaella moo, polymers ka felisa repulsion electrostatic pakeng tsa likaroloana ka qoso neutralization, lumella likaroloana ho atamela le agglomerate hammoho.
Mokhoa oa ts'ebetso oa li-polymer ho hloekisa metsi a litšila
Mochini oa ts'ebetso ea li-polymers joalo ka li-flocculants li ka aroloa ka mehato e meraro: ho se nke lehlakore ka tefiso, ho phalla ha bridging le ho ts'oaroa ha marang-rang. Ntlha ea pele, polymer e felisa ho repulsion electrostatic pakeng tsa likaroloana ka ho se nke lehlakore, ho lumella likaroloana ho atamela. Joale polymer e kopanya likaroloana ho etsa lihlopha tse kholoanyane ka ho phalla ha bridging. Qetellong, lihlopha tsena li kopanngoa le ho lula ka metsing ka ho fiela ha matlooa.
Lintlha tse amang katleho ea li-Polymers ho phekola metsi a litšila
Ho na le lintlha tse ngata tse amang katleho ea phekolo ea polymer ea metsi a litšila, ho kenyelletsa le mofuta oa polymer, litekanyetso, boleng ba pH, mocheso, lebelo le susumetsang, joalo-joalo Har'a tsona, mofuta oa polymer le litekanyetso ke e 'ngoe ea lintlha tsa bohlokoa ka ho fetisisa. Mefuta e fapaneng ea li-polymers e na le thepa e fapaneng ea litefiso le kabo ea boima ba limolek'hule, ka hona hoa hlokahala ho khetha mofuta o nepahetseng oa polymer le litekanyetso bakeng sa metsi a litšila a fapaneng ho fihlela phello e ntle ea kalafo. Ntle le moo, lintlha tse joalo ka boleng ba pH, mocheso, le lebelo le susumetsang le tsona li tla ama ts'ebetso ea kalafo, 'me maemo a nepahetseng a tlameha ho khethoa ka liteko.
Li-polymers li bapala karolo ea bohlokoa e le li-flocculants ho hloekisa metsi a litšila. Kutloisiso e tebileng ea mokhoa oa ts'ebetso le lintlha tse susumetsang tsa li-polymers li ka fana ka ts'ehetso ea bohlokoa ea theory le tataiso e sebetsang bakeng sa ho ntlafatsa lits'ebetso tsa ho hloekisa metsi a litšila le ho ntlafatsa ts'ebetso ea kalafo. Nakong e tlang, ka ntlafatso e tsoelang pele ea litlhoko tsa tšireletso ea tikoloho le tsoelo-pele e tsoelang pele ea saense le thekenoloji, ho lumeloa hore tšebeliso ea li-polymers ho hloekisa metsi a litšila e tla ba e pharaletseng le e tebileng.
