Peb txhua tus paub tias hydrogen peroxide feem ntau yog siv rau kev kho mob, tub rog, thiab tshuaj tua kab mob txhua hnub. Txawm li cas los xij, kev lag luam hydrogen peroxide muaj ib qho kev siv ntxiv, uas yog, nws yog siv los tswj cov dej paug. Txawm li cas los xij, raws li oxidant, hydrogen peroxide yog siv rau cov dej paug. Dab tsi yog siv?
Txij li thaum muaj hydrogen peroxide feem ntau muaj hydroxide thiab sodium ions, hydroxide tuaj yeem ua ke nrog ntau hom hlau ions los ua flocs lossis precipitates. Piv txwv li, raws li peb txhua tus paub, dej phwj muaj hlau ions xws li txhuas ions los yog hlau ions, muaj zog acid ntsev thiab qaug zog acid ntsev, thiab lwm yam, uas reacts nrog hydroxide ions los tsim flocs los yog insoluble precipitates. Lub hauv paus ntsiab lus ntawm flocculation yog tsuas yog ua ke nrog hydroxide hauv cov dej phwj tuaj tsim cov tshuaj flocculent kom ua tiav cov nyhuv flocculation. Nws tseem tuaj yeem tshem tawm cov kua qaub ntau dhau hauv cov dej phwj tuaj, xws li Cl-(SO4) 2-(PO4) 3, thiab lwm yam. Nws kuj tseem siv tau los kho tus nqi pH, thiab qhov ntau npaum li cas ntawm hydrogen peroxide yog txiav txim siab. raws li pH.
Kev tiv thaiv ib puag ncig tuaj yeem kho txhua yam dej khib nyiab, suav nrog kev tshem tawm, deodorization, thiab decolorization, tshwj xeeb tshaj yog tsim rau kev kho dej khib nyiab ntawm sulfur compounds, cyanide, thiab phenols. Nws tuaj yeem siv ib leeg lossis ua ke nrog ozone lossis UV teeb. Siv hydrogen peroxide los ntxuav cov av uas muaj kuab paug los ntawm cov roj xau los yog lwm yam khoom siv organic tuaj yeem ua rau muaj cov kab mob regrowth, degrade cov pa phem, thiab kho cov pa khib nyiab uas muaj NOx, SO2, H2S, thiab lwm yam, uas tuaj yeem tsim cov concentrated nitric acid thiab concentrated sulfuric. kua qaub. Hydrogen peroxide kuj tseem txhim kho lub peev xwm ntawm cov txheej txheem biochemical los kho cov dej khib nyiab thiab tiv thaiv sludge bulking. Thaum cov dej khib nyiab raug kho, cov pa roj carbon activated siv hauv cov pa khib nyiab tuaj yeem rov tsim dua nrog hydrogen peroxide.
