Kev qhia tshwj xeeb rau kev siv sodium bromide hauv kev kho dej

Sodium bromide (NaBr), thaum tsis siv dav hauv kev kho dej raws li cov tshuaj tua kab mob xws li tshuaj chlorine lossis chlorine dioxide, muaj txiaj ntsig zoo raws li cov xwm txheej tshwj xeeb vim nws cov ntsiab lus bromine. Nws cov ntawv thov tseem ceeb yog nyob rau hauv cov hauv qab no:

I. Synergistic Disinfection

Sodium bromide nws tus kheej muaj kev txwv cov kab mob bactericidal, tab sis thaum siv ua ke nrog oxidizers xws li chlorine los yog ozone, nws reacts los tsim hypobromous acid (HBrO) los yog elemental bromine (Br₂), yog li txhim kho tag nrho cov tshuaj tua kab mob. Lub generated hypobromous acid zoo rhuav tshem microbial cell lug, tua kab mob, kab mob, thiab algae.

Hauv cov dej hauv lub cev uas muaj pH siab dua (xws li qee cov dej hauv kev lag luam), bromine - cov tshuaj tua kab mob yog ruaj khov dua li cov tshuaj chlorine - cov tshuaj tua kab mob, lawv cov kab mob bactericidal tsis cuam tshuam los ntawm pH, thiab lawv tuaj yeem txo qhov tsim ntawm cov khoom siv xws li trihalomethanes. Qhov no ua rau lawv tsim nyog rau cov ntawv thov xws li cov pas dej da dej thiab cov dej txias ua haujlwm, qhov chaw tshuaj tua kab mob thiab kev nyab xeeb ib puag ncig yog qhov tseem ceeb.

II. Inhibition ntawm Biofilm Tsim

Nyob rau hauv kev lag luam circulating dej systems, sodium bromide yuav siv tau ua ke nrog oxidizing biocides xws li chloramines thiab chlorine dioxide los tsim ib tug bromine -raws li ib puag ncig nrog tas li tshuaj tua kab mob. Qhov no inhibits qhov txuas ntawm cov kab mob, fungi, thiab algae mus rau qhov chaw ntawm cov kav dej thiab cov khoom siv hluav taws xob, txo qis kev tsim biofilm thiab txo qis kev pheej hmoo ntawm txhaws thiab xeb, yog li pab tswj kev ua haujlwm ntawm cov cua sov.

III. Kev Pab Cuam Tshem Tawm Ntawm Cov Kabmob Tshwj Xeeb

Hauv qee cov txheej txheem kev kho dej khib nyiab, sodium bromide tuaj yeem siv los ua tus neeg sawv cev pabcuam kom tshem tawm qee yam hlau hnyav lossis cov pa phem:

Bromide ions tuaj yeem tsim cov bromide insoluble precipitates nrog hnyav hlau ions xws li nyiaj thiab mercury (piv txwv li, AgBr, HgBr₂), ua kom cov hlau hnyav tshem tawm los ntawm cov khoom sib cais - kua.

Nyob rau hauv cov txheej txheem oxidation siab heev, sodium bromide tuaj yeem koom nrog cov tshuaj tiv thaiv dawb radical, pab hauv kev degradation ntawm qee cov organic tebchaw, tab sis nws daim ntawv thov yuav tsum tau soj ntsuam thiab kho raws li cov dej zoo.

IV. Kev ceev faj rau kev siv

Sodium bromide feem ntau tsis siv ib leeg ua tus neeg saib xyuas dej; Nws yuav tsum tau ua ke nrog oxidizers kom ua tau zoo. Cov koob tshuaj yuav tsum nruj me ntsis tswj kom tsis txhob muaj bromide ion residue ntau dhau los cuam tshuam rau kev kho dej tom qab lossis ua raws li cov qauv kev tso tawm.

Tus neeg sawv cev no yog tam sim no tsuas yog siv rau hauv cov ntawv thov tshwj xeeb xws li cov dej txias thiab dej hauv pas dej da dej, thiab tsis yog qhov kev xaiv tseem ceeb rau cov dej khib nyiab hauv nroog lossis kev kho dej haus. Hauv kev siv tswv yim, nws yuav tsum tau ua tib zoo soj ntsuam ua ke nrog cov yam ntxwv ntawm cov dej zoo thiab cov txheej txheem yuav tsum tau ua.
