Tau ua haujlwm hauv kev lag luam no ntau tshaj kaum xyoo, kuv tau nug ntau zaus: Dab tsi yog cov khoom tseem ceeb tshaj plaws hauv kev kho dej? Kuv qhia koj tias nws tsis yog qhov rov qab osmosis membrane, tsis yog cov pa roj carbon activated, tab sis qhov tsis zoo tshaj plaws quartz xuab zeb lim.
Lub luag haujlwm ntawm quartz xuab zeb lim yog ua "kev ua haujlwm ntxhib" - lim tawm cov khoom loj ntawm impurities los ntawm dej.
Cov dej nyoos nkag mus rau hauv lub tank los ntawm cov yeeb nkab inlet thiab sib npaug sib npaug saum cov quartz xuab zeb lim txheej los ntawm tus neeg faib khoom. Cov dej ntws los ntawm cov txheej lim dej, thiab cov khoom tsis zoo xws li cov xuab zeb, xeb, tshem tawm cov khib nyiab, thiab cov colloids raug kaw los ntawm qhov khoob ntawm cov xuab zeb quartz. Cov dej huv ntws tawm los ntawm cov khoom siv hauv qab, thaum cov impurities tseem nyob hauv cov xuab zeb txheej. Tag nrho cov txheej txheem yog kev cuam tshuam lub cev nkaus xwb, tsis muaj qhov sib ntxiv ntawm cov tshuaj.
quartz xuab zeb lim xov xwm muaj qhov sib txawv particle loj; txheej sab sauv yog finer, intercepting me me hais, thaum lub qis txheej yog coarser, xyuas kom meej cov dej txaus txaus. Cov qauv tsim qib no ua kom pom tseeb qhov tseeb thiab kev tsim dej txaus.
Nws ua tau zoo npaum li cas? Quartz xuab zeb lim tuaj yeem tshem tawm ntau dua 90% ntawm cov khib nyiab tshem tawm. Muaj qhov sib txawv tseem ceeb ntawm turbidity ntawm tus muaj zog thiab cov dej ntws tawm - qhov muaj zog turbidity tuaj yeem yog kaum ntawm NTU lossis siab dua, thaum cov dej turbidity tuaj yeem tswj tau qis dua 1 NTU tom qab pom, ua tau raws li qhov xav tau ntawm cov khoom siv hauv qab. Tus tsim pom tus nqi feem ntau yog 8 mus rau 12 meters ib teev, thiab kev ua tau zoo tuaj yeem rov qab tau tom qab ntxuav rov qab; lub lim xov xwm nws tus kheej tsis tas yuav hloov ntau zaus.
Nws tus nqi yog dab tsi? Lub quartz xuab zeb lim ua raws li "tus neeg saib xyuas," khaws cov kab mob tawm thiab tiv thaiv cov khoom siv kim dua thiab cov khoom siv hauv qab. Yog tsis muaj quartz xuab zeb lim, thim rov qab osmosis daim nyias nyias yuav sai sai siv tsis tau, thiab cov pa roj carbon activated yuav sai sai no clogged nrog sludge. Nws yog pheej yig, tsis ilv, thiab yooj yim rau siv, tab sis indispensable.
