Cov tshuab hluav taws xob muaj cov pa oxygen tau siv dav hauv kev kho dej hauv ntau qhov kev lag luam vim lawv cov tshuaj lom neeg muaj zog los ntawm peb cov pa oxygen molecules uas tsim lawv.Kev lag luam tsim cov pa oxygen los ntawm kev kho dej ua ke nrog lub tswv yim tseem ceeb ntawm kev kho dej ntsuab.Lub tshuab hluav taws xob muaj oxygen tuaj yeem lim tawm cov pa phem hauv dej thiab decompose rau hauv o2 los ntawm huab cua oxidation.Cov cuab yeej siv tshuab hluav taws xob muaj cov pa oxygen ua lub luag haujlwm tseem ceeb hauv kev kho cov dej haus (dej kais dej, dej huv, dej ntxhia, thiab dej caij nplooj ntoos hlav), kev kho dej khib nyiab thiab pov tseg, kev ua luam dej hauv pas dej, kev siv dej rov siv dua, thiab kev tsim khoom noj thiab dej haus. .
Hauv kev tsim cov tshuab hluav taws xob kho mob, lawv tau siv los kho cov dej haus thiab muab cov txiaj ntsig zoo xws li tshuaj tua kab mob, decolorization, tshem tawm tsw, thiab tshem tawm cov hlau, manganese, thiab permanganate.Cov tshuab cua oxidation kuj tseem siv los decompose organic tebchaw, tswj thiab kawm txog kev loj hlob ntawm algae, txhim kho saj, thiab tiv thaiv ib puag ncig los ntawm kev tiv thaiv cov pa phem thib ob uas yuav tshwm sim los ntawm kev siv chlorine dioxide.Cov chaw tsim khoom noj khoom haus thiab dej haus kuj tuaj yeem siv cov tshuab hluav taws xob muaj oxygen los tsim ntau yam tshuaj tua kab mob.
Hauv cov pas dej da dej, cov tshuab hluav taws xob muaj cov pa oxygen tuaj yeem tua kab mob thiab tshem tawm cov khoom siv organic, txhim kho cov xim ntawm cov dej, txhim kho pH qib, tiv thaiv cov tshuaj fluoride thiab tsis xis nyob, tawv nqaij khaus, thiab tsw los ntawm hydrogen sulfide cov tshuaj tiv thaiv, thiab txo cov tshuaj siv tshuaj.
Cov tshuab hluav taws xob muaj oxygen kuj tuaj yeem siv rau hauv tsev kho mob sab nrauv kho cov dej khib nyiab thiab muaj qhov zoo xws li tshuaj tua kab mob sai thiab ua kom tsis muaj menyuam, tshem tawm ntau yam kab mob, tshem tawm cov kab mob xws li chlorine thiab cyanide, txhim kho cov dej yaj cov pa oxygen, decomposition ntawm refractory organic compounds thiab dioxins. , kev txhim kho kev lom neeg thiab tshuaj lom neeg cov yam ntxwv ntawm cov dej khib nyiab, yooj yim ntawm decomposition, thiab kev pheej hmoo tsawg kawg ntawm cov pa phem thib ob.
Hauv kev kho dej khib nyiab hauv kev lag luam, cov tshuab hluav taws xob muaj cov pa oxygen tuaj yeem tshem tawm cov kab mob zoo, tua kab mob thiab ua kom tsis muaj menyuam, decolorize, tshem tawm tsw, thiab tsis muaj pa phem thib ob.Lawv kuj tuaj yeem siv rau kev kho dej khib nyiab, sai sai decompose cyanide thiab phenols, tshem tawm cov teeb meem, txo qis COD, thiab kho cov dej txias los ntawm kev tshem cov kab mob, algae, thiab nplai.
Piv nrog rau cov txheej txheem ib txwm siv ntawm kev ntxiv tshuaj thiab tshuaj chlorine rau kev kho dej, kev siv cov tshuab hluav taws xob muaj oxygen hauv kev kho dej yog nrov zuj zus vim lawv tsis hloov cov dej muaj pes tsawg leeg, tab sis tuaj yeem tshem tawm cov ntxhiab tsw thiab txo cov concentration ntawm tag nrho cov organic tebchaw. , txhim kho cov xim thiab zoo ntawm cov dej thiab muab cov txiaj ntsig tseem ceeb hauv cov dej khib nyiab rov siv dua thiab kev tiv thaiv ib puag ncig.
