Kev sib xyaw ntawm cov khoom siv dej ntshiab huv

Lub desalination core tivthaiv ntawm ultra-ntshiab dej system khoom siv yog ib qho txawv teb rov qab osmosis membrane module. Cov khoom siv dej ntshiab ultra-ntshiab feem ntau yog tsim los ntawm kev kho ua ntej, qhov rov qab osmosis tus tswv tsev, thiab ib feem tom qab kho.

1. Pretreatment muaj quartz xuab zeb lim, activated carbon lim, siab tsis siv neeg dej softener, thiab precision lim (peb lub tuam txhab txais tag nrho tsis siv neeg tswj valve hau). Ultrafiltration system kuj raug xaiv los ua pretreatment, tab sis feem ntau qhov project nqi yog siab. Lub hom phiaj tseem ceeb ntawm pretreatment yog tshem tawm sediment, xeb, colloidal tshuaj, tshem tawm cov khib nyiab, chromaticity, tsw, thiab biochemical organic tshuaj muaj nyob rau hauv cov dej nyoos. Thaum lub hardness ntawm cov dej nyoos yog siab, lub siab tsis siv neeg dej softener tuaj yeem xaiv, uas muaj txiaj ntsig zoo tiv thaiv qhov rov qab osmosis membrane, yog li txuas ntxiv kev pab cuam lub neej ntawm rov qab osmosis membrane.

2. Tus tswv tsev rov qab osmosis feem ntau muaj cov twj tso kua mis siab, cov khoom siv membrane, cov khoom siv rov qab osmosis membrane, cov khoom siv hauv online, tswj hluav taws xob, thiab lwm yam. Tsuav yog cov naj npawb ntawm daim nyias nyias thiab cov qauv xaiv ntawm cov twj tso kua mis tsim nyog, lub desalination. tus nqi thiab dej tawm los ntawm tus tswv tsev rov qab osmosis tuaj yeem ua tau raws li cov ntsuas ntsuas, thiab cov khoom siv hluav taws xob tuaj yeem lav tau kom tsawg dua lossis sib npaug li 10us Hauv qab CM, (cov dej tsis zoo yog tsawg dua 500us / cm, ua haujlwm kub: 1. ~ 40 degree)

3. Qhov kev kho tom qab yog txhawm rau txhawm rau kho cov dej ntshiab uas ua los ntawm rov qab osmosis los tsim cov dej ntshiab huv, feem ntau yog siv ion txauv cov khoom siv txaj txaj lossis EDI cov khoom siv. Raws li cov neeg siv khoom xav tau, cov dej tsis kam tuaj yeem ncav cuag 18.2 M Ω. CM. Yog tias nws tau siv rau cov txheej txheem haus dej ncaj qha, nws txaus los ntxiv cov khoom siv kom tsis muaj menyuam, feem ntau yog ultraviolet sterilizer lossis lub tshuab hluav taws xob ozone, ua kom cov dej tsim tau raws li tus qauv haus dej ncaj qha.

Kev sib pauv cov tshuaj tiv thaiv tshwm sim nyob rau hauv cov tshuaj dawb huv chamber ntawm lub module, qhov twg anion pauv resins siv lawv hydrogen thiab oxygen los pauv anions (xws li chloride ions Cl) nyob rau hauv yaj ntsev raws li ions (OH). Yog li, cation txauv resins siv lawv cov hydrogen ions (H) pauv cations (xws li Na) hauv cov ntsev yaj.
