Hajoale, COD e tloaelehileng ea metsi a litšila e feta tekanyetso haholo-holo e kenyelletsa electroplating, board board, papermaking, meriana, masela, khatiso le dae, lik'hemik'hale le metsi a mang a litšila, joale mekhoa ea kalafo ea metsi a litšila a COD ke efe?Ha re yeng re bone mmoho.
Phapang ea COD ea metsi a litšila.
Mehloli ea metsi a litšila a hlahisoang e arotsoe ka: metsi a litšila a indasteri, metsi a litšila a temo, le metsi a litšila a bongaka.
Likhoerekhoere tsa ka tlung li bolela motsoako o rarahaneng oa mefuta e fapaneng ea lintho tse phelang tse entsoeng ka lintho tse sa pheleng le tse phelang, ho akarelletsa:

Mekhoa ea kalafo ea metsi a litšila a COD e kenyelletsa:
Ho tlosoa ha COD ka mokhoa oa coagulation: mokhoa oa ho kopanya lik'hemik'hale o ka tlosa lintho tse phelang metsing a litšila le ho fokotsa COD haholo.Ts'ebetso ea coagulation e amoheloa, ka ho eketsa flocculant, ho sebelisa adsorption le bridging ea flocculant, motlakase o habeli o hatelloa, e le hore taba ea colloid le e emisitsoeng ka metsing e fokotsehe, e thulane, 'me e fokotsehe ka har'a lihlopha, ebe sedimentation kapa moea. flotation tshebetso e sebelisoa ho tlosa Particles ba arohanngoa le metsi, e le ho finyella morero oa ho hloekisa 'mele oa metsi.
Mokhoa oa likokoana-hloko oa ho tlosa COD: Mokhoa oa likokoana-hloko ke mokhoa oa ho hloekisa metsi a litšila o itšetlehileng ka li-enzyme tsa likokoana-hloko ho oxidize kapa ho fokotsa lintho tse phelang ho senya li-unsaturated bonds le chromophores ho finyella morero oa phekolo.Lilemong tsa morao tjena, likokoana-hloko li 'nile tsa sebelisoa haholo ho phekola metsi a litšila ka lebaka la lebelo la tsona la ho ikatisa ka potlako, ho ikamahanya le maemo ho matla le theko e tlaase.
Ho tlosoa ha electrochemical COD: Moko oa phekolo ea metsi a litšila a electrochemical ke ho sebelisa electrolysis ka ho toba kapa ka tsela e sa tobang ho tlosa litšila tse ka metsing, kapa ho fetola lintho tse chefo hore e be lintho tse se nang chefo le tse fokolang.
Ho tlosoa ha COD ka micro-electrolysis: Theknoloji ea Micro-electrolysis hona joale ke mokhoa o loketseng oa ho phekola metsi a litšila a mangata, a tsejoang hape e le electrolysis ea ka hare.Tlhahiso ena e sebelisa lisebelisoa tsa micro-electrolysis ho tlatsa metsi a litšila tlas'a boemo ba ho se be le motlakase, 'me e hlahisa 1.2V e ka bang teng ka boeona ho etsa hore metsi a litšila a etsoe ka electrolyze ho finyella morero oa ho senya litšila tse phelang.
Ho tlosoa ha COD ka mokhoa oa ho monya: khabone e kentsoeng, macroporous resin, bentonite le lisebelisoa tse ling tse sebetsang tsa adsorption li ka sebelisoa ho bapatsa le ho phekola likaroloana tsa tlhaho le chroma ka likhoerekhoere.E ka sebelisoa e le kalafo ea pele ho fokotsa COD eo ho leng bonolo ho e sebetsana.
Mokhoa oa oxidation oa ho tlosa COD: Lilemong tsa morao tjena, ts'ebeliso ea theknoloji ea oxidation ea photocatalytic tšimong ea kalafo ea metsi a litšila e na le menyetla e metle ea 'maraka le melemo ea moruo, empa ho ntse ho e-na le mathata a mangata lipatlisisong tsa lefapha lena, joalo ka ho fumana li-catalyst tse sebetsang hantle haholo. , karohano le ho hlaphoheloa ha li-catalyst li emetse.
