Cov khoom siv kho dej yog ib qho tseem ceeb ntawm cov txheej txheem kho dej. Lawv ua lub luag haujlwm tseem ceeb hauv cov txheej txheem kho dej, kom ntseeg tau tias cov dej zoo ua tau raws li cov qauv kev xav tau thiab ua tiav cov kev xav tau ntawm ntau yam kev thov.
Cov khoom siv kho dej muaj ntau yam, suav nrog txhua yam ntawm kev kho ua ntej mus rau kev kho mob siab, tom qab- kho, thiab cov cuab yeej pabcuam.
Hauv theem pretreatment, feem ntau siv cov khoom siv kho dej muaj xws li cov ntxaij vab tshaus, sieves, thiab cov ntxaij lim dej. Bar cov ntxaij vab tshaus thiab sieves feem ntau yog siv los tshem tawm cov impurities loj hauv dej, xws li tshem tawm cov khib nyiab thiab cov teeb meem ntab, tiv thaiv cov impurities los ntawm kev nkag mus rau cov chav kho mob tom ntej thiab ua rau muaj kev cuam tshuam los yog puas tsuaj. Cov lim dej ntxiv ua kom zoo dua cov txheej txheem pom, thiab nyob ntawm qhov pom tseeb, lawv tuaj yeem muab faib ua cov lim ntxhib, lim nruab nrab, thiab cov ntxaij lim dej zoo, tshem tawm cov khoom me me thiab cov khib nyiab hauv dej.
Hauv cov txheej txheem kev kho mob tseem ceeb, kev xaiv cov khoom siv kho dej ua kom muaj ntau haiv neeg. Piv txwv li, hauv kev kho softening, ion exchange resin yog ib qho tseem ceeb accessory. Nws tuaj yeem tshem tawm calcium thiab magnesium ions los ntawm dej los ntawm kev sib pauv ion, txo cov dej tawv thiab tiv thaiv kev tsim cov nplai. Hauv kev kho rov qab osmosis, rov qab osmosis membrane yog qhov tseem ceeb. Siv lub hauv paus ntsiab lus ntawm ib nrab -permeable membrane, nws yuam cov dej molecules los ntawm nyob rau hauv lub siab thaum ntxiab impurities, yog li ua tiav dej purification.
Tsis tas li ntawd, tom qab- cov khoom siv kho dej kho mob kuj tseem ceeb heev. Piv txwv li, ultraviolet (UV) sterilizers siv UV hluav taws xob los cuam tshuam cov qauv microbial hauv dej, ua kom tsis muaj menyuam. Cov pa roj carbon activated siv cov khoom adsorption ntawm cov pa roj carbon activated kom tshem tawm cov chlorine seem, ntxhiab tsw, thiab lwm yam teeb meem, txhim kho saj thiab zoo ntawm cov dej.
Dhau li ntawm cov khoom tseem ceeb no, lub tshuab kho dej yuav tsum muaj cov cuab yeej pabcuam los xyuas kom meej tias nws ua haujlwm li qub. Piv txwv li, lub twj tso kua mis dej yog cov cuab yeej tseem ceeb uas muab lub zog rau cov dej ntws, thiab nws qhov kev ua tau zoo cuam tshuam ncaj qha rau kev kho lub peev xwm thiab kev ua haujlwm ntawm kev kho dej. Flow meters saib xyuas cov dej ntws kom ntseeg tau tias lub kaw lus ua haujlwm raws li kev teeb tsa. Cov ntsuas ntsuas ntsuas pom lub siab nyob rau hauv lub kaw lus, pab cov neeg ua haujlwm kho thiab ua kom lub cev ua haujlwm zoo raws sijhawm.
Thaum xaiv cov khoom siv kho dej, ntau yam yuav tsum tau txiav txim siab, xws li cov yam ntxwv zoo ntawm cov dej, kev kho kom zoo, thiab qhov ntsuas qhov system. Nyob rau tib lub sijhawm, kev saib xyuas yuav tsum tau them rau qhov zoo, kev ua tau zoo, lub neej ntev, thiab tom qab - kev muag khoom ntawm cov khoom. High-cov khoom siv kho dej zoo tsis yog tsuas yog txhim kho kev ruaj ntseg thiab kev ntseeg siab ntawm kev kho dej, tab sis kuj txo cov nqi khiav lag luam thiab kev saib xyuas, nqa mus ntev - cov txiaj ntsig kev lag luam rau cov neeg siv.
Tsis tas li ntawd, nrog kev txhim kho thev naus laus zis thiab kev paub txog ib puag ncig, cov khoom siv kho dej tau hloov kho tas li. Cov khoom siv tshiab tshiab tsis yog tsuas yog muab kev kho kom zoo dua qub thiab cov txiaj ntsig kev kho mob zoo dua tab sis kuj tseem ceeb dua rau kev txuag hluav taws xob, kev tiv thaiv ib puag ncig, thiab kev tswj xyuas ntse. Piv txwv li, qee cov khoom siv kho dej ntse tuaj yeem saib xyuas cov dej zoo hauv lub sijhawm tiag tiag thiab tuaj yeem kho cov kev kho tsis zoo, ua tiav kev kho dej ntau dua thiab ua tau zoo.
