Yuav daws qhov teeb meem lim dej ntawm cov cuab yeej siv dej lim nrog li cas?
Cov cuab yeej siv dej ua kom huv huv tuaj yeem ua tau raws li qhov ua tau zoo ntawm cov dej haus ntawm cov chaw tsim tshuaj thiab tsev kho mob, xws li kev ua dej huv, kev npaj ua loj thiab lwm yam. Nws yog dav siv hauv tshuaj, biochemistry, tshuaj lom neeg kev lag luam, tsev kho mob thiab lwm yam lag luam. Xyoo tsis ntev los no, Tuam Tshoj' s kev lag luam kws tshuaj tau tsim muaj sai heev. Qee cov ntaub ntawv kwv yees tias thaum xaus 2020, kev ua lag luam nplai ntawm Tuam Tshoj' s kev lag luam kws tshuaj yuav ncav cuag 1,79 trillion yuan, uas tseem coj cov hauv kev lag luam ntxiv rau kev lag luam khoom siv dej huv. Nyob rau tib lub sijhawm, nrog kev tswj hwm nruj ntau ntxiv ntawm kev lag luam kws kho mob, kev lag luam kws tshuaj kuj tseem tso cov kev cai siab dua rau cov dej huv ntawm cov khoom siv dej lim.
Lub lim dej yog lub siab ntawm cov khoom siv lim dej, uas ua lub luag haujlwm txiav txim siab hauv qhov zoo ntawm cov dej tsis huv, yog li nws tsim nyog tiv thaiv zoo rau txhua theem ntawm cov khoom lim. Nws to taub tias cov cuab yeej siv dej huv feem ntau yog tsim los ntawm PPC, cov roj carbon activated, RO membrane thiab lwm cov khoom lim. Txhua theem ntawm cov khoom lim muaj cov haujlwm sib txawv. Piv txwv li, thawj qib qib kev ua ntej yuav tshem tawm cov khoom loj, cov tshuaj muaj kuab tshuaj, calcium ions thiab magnesium ions hauv dej kom tau txais txiaj ntsig zoo ua ntej; theem ob ntawm thim rov qab osmosis tuaj yeem lim feem ntau cov pa phem nrog rau cov inorganic ions; qib thib peb ntawm kev sib pauv ion tuaj yeem tshem cov tshuaj ionic.
Txhawm rau kom ntseeg tau tias qhov zoo ntawm cov dej tsim, lub lim lim cov teeb meem ntawm cov cuab yeej siv dej lim yuav tsum daws nyob rau lub sijhawm. Ntawm ib sab, nws yuav tsum tau txhim kho kom raug, txwv tsis pub nws yuav tsis muaj peev xwm ua kom muaj kev ruaj khov ntawm cov lag luam tshuaj siv dej huv, ua rau muaj dej paug. Ua ntej kev teeb tsa, nws yog ib qho tsim nyog yuav tsum tau them sai sai rau seb lub chaw teeb tsa tiaj tus, puas yog qhov chaw ib puag ncig huv thiab seb qhov chaw teeb tsa tau zoo; thaum lub sijhawm teeb tsa, txhua cov raj xa dej, cov hlua, cov khoom siv thiab cov ntu loj yuav tsum sib dhos raws li cov lus qhia tshwj xeeb thiab cov qauv, thiab cov paib cuam tshuam yuav tsum dhau los.
Ntawm qhov tod tes, yog tias lub lim lim siv lub sijhawm ntev, nws yuav nqus tau ntau yam tsis huv, uas yuav ua rau txhaws thiab ua rau lub peev xwm lim dej tsis zoo. Yog li, nws yog qhov yuav tsum tau hloov lub lim dej tsis tu ncua kom tsis txhob muaj cov pa phem zaum ob rau dej.
Tus sau tau kawm paub tias vim yog tus nqi siab thiab tus nqi ntawm lub lim lim, ntau cov neeg siv yuav xav kom tshem tawm cov khoom lim tawm thiab ntxuav nws, thiab tom qab ntawd nruab rau nws rov qab. Yog li cov txuj ci no puas yog?
Hauv qhov no, qee tus kws qhia tawm tau taw qhia tias txoj kev xav tau no tsis yog qhov xav tau. Qhov laj thawj yog hais tias tus qauv ntawm lub taub lim yog txoj. Tom qab nqus tau cov impurities ntau dhau lawm, lub caij lim dej yuav hloov xim. Tso dej tawm yooj yim tsis tuaj yeem tshem tawm cov khoom tsis huv nyob hauv lub lim, thiab tsis tuaj yeem lav qhov ua tau zoo ntawm cov lim. Yog li, txhawm rau txhim kho cov dej ua kom tsis muaj peev xwm ntawm cov khoom siv lim dej, nws yog qhov yuav tsum hloov cov lim dej tsis tu ncua.
Yog li, ntau npaum li cas cov lim dej huv ntawm cov khoom siv lim dej yuav tsum tau hloov? Tus kws tshaj lij hais tias raws li cov lim sib txawv, hloov lub sijhawm hloov mus tsis yog tib yam. Nyob rau hauv ib txwm muaj tshwm sim, lub hloov hloov ntawm ultrafiltration cov khoom lim lub caij yog 12-24 lub hlis, uas ntawm kev siv lub tshuab lim roj yog 6-18 lub hlis, thiab qhov rov qab hloov osmosis membrane lim keeb yog 18-36 hlis.
Ntxiv rau qhov yuav tsum tau them sai sai rau kev tiv thaiv ntawm cov khoom lim, qhov tsis zoo ntawm cov khoom lim kuj tseem ceeb heev, uas tseem ceeb toom cov tuam ntxhab kom xav txog tsis yog tus nqi nkaus xwb, tab sis kuj tsim cov khoom lag luam zoo thaum xaiv lub lim, thiaj li zam kev coj zais kev phom sij rau kev tsim khoom tom qab thiab ua rau kev lag luam poob peev.
