Metsi a litšila a dailoeng a hlahisoang ke leloala la masela a silafatsa tikoloho haholo. Ka hona, metsi a litšila a hloka ho ts'oaroa pele a ka tsoa kapa a sebelisoa bocha. Ozone ke motsoako o matla haholo 'me e bapala karolo ea bohlokoa kalafong ea metsi a litšila.
Ho hatisa le ho daea metsi a litšila ke metsi a likhoerekhoere a nang le chroma e kholo, lihlahisoa tse phahameng tsa 'mele le sebopeho se rarahaneng. Metsi a na le lidae tse ngata tse setseng, alkalis, diazo, azo, jj, tse thata ho sebetsana le tsona. Metsi a litšila a masela hangata a phekoloa ka mekhahlelo e meraro:
Pele: kalafo ea 'mele, e arohantsoeng ke sedimentation le grid filtration;
Ea bobeli: kalafo ea lik'hemik'hale, ho eketsa lisebelisoa tsa lik'hemik'hale ho ntlafatsa boleng ba metsi;
Ea boraro: kalafo e tsoetseng pele, ho sebelisa theknoloji ea ozone oxidation , ho fokotsa boleng ba COD, BOD, le ho ntlafatsa ts'ebeliso ea ts'ebeliso ea metsi kapa ho latela.
Mochini oa ts'ebetso ea ozone:
Ozone e na le oxidant e matla, 'me matla a eona a redox ka metsing a bobeli ho feta fluorine. E sebelisoa khafetsa kalafong ea kalafo le kalafo e tsoetseng pele ea metsi a litšila a liindastering. E na le mesebetsi e mengata kalafong ea metsi, ho nyopisa, ho tlosa lipompo, ho tlosa metsi lehare, ho tlosa metsi le ho bola ha oxidative. Ozone e sebelisoa haholoholo ho phethola 'mala le ho nyenyefatsa manyolo le ho fokotsa boleng ba COD le BOD kalafong ea ho hatisa le ho daea metsi a litšila.
Ha o sebetsana le chromaticity ea ho hatisa le ho daea metsi a litšila, ozone oxidation e ka roba tlamo e ts'oanang ea phepelo ea dae kapa chromogenic ea dae, mme ka nako e ts'oanang e senye motsoako oa cyclic o etsang sehlopha sa chromophore, ka tsela eo o silafatsa metsi a litšila.
Ozone e itšoara ka lintho tse thata ho senyeha, tse fetolang chefo ea lintho tse silafatsang le ho senyeha ha likokoana-hloko. Ka nako e ts'oanang, fokotsa COD le BOD, o ntlafatse boleng ba metsi. Ozone e ka kopanya lintho tse ngata tsa manyolo le likokoana-hloko metsing a litšila, mme ea fokotsa boleng ba eona ba COD le BOD ntle le tšilafalo ea bobeli le ho bola habonolo. Ka nako e ts'oanang, e ka hlakola, ea nyopa le ho fepa. E sebelisitsoe haholo kalafong e tsoetseng pele ea kalafo ea metsi a litšila.
