Nrog cov xwm txheej kub ntawm kev ua luam dej hauv Beijing 2008 Olympic Games, qhov nrov ntawm cov pas dej da dej thiab kev txhim kho qib, qee qhov tuaj yeem ua tau raws li cov kev xav tau ntawm cov dej zoo dua thiab kev txuag hluav taws xob ntau dua, cov cuab yeej tshiab, cov cuab yeej tshiab, yog maj mam muab tso rau hauv cov pas dej da dej ntau dua. Txawm hais tias lub pas dej ua ke tshiab (natatorium) lossis lub pas dej da dej tseem nyob hauv kev kho dua tshiab ntawm lub pas dej ua ke tau ntsib teeb meem ntawm yuav ua li cas xaiv lub pas dej da dej zoo.
Cov yam ntxwv ntawm diatomite txiav txim siab nws daim ntawv thov teb. Diatomite yog tus cwj pwm siab, qis ntom ntom, thaj chaw tshwj xeeb thaj tsam, tsis zoo, tsis muaj tshuaj lom thiab tshuaj lom neeg. Nws yog ib qho zoo heev lim auxiliary khoom. Kev siv tshuab hauv tsev hauv kev kho dej phwj tuaj, npias, zaub mov thiab dej haus pom muaj ntau yam kev siv
Nyob rau hauv txawv teb chaws, diatomite filtration technology thiab cov cuab yeej siv tau dav siv nyob rau hauv lub circulating dej kho system ntawm ua luam dej pas dej ua ke. Vim muaj zog adsorption ntawm diatomite lim pab, nws tuaj yeem nqus dej 1.5-4 npaug ntawm nws tus kheej. Nws lub peev xwm yog qhov tsis zoo, nws tus nqi tiag yog qhov loj, thiab nws lub peev xwm los nqus cov nqi zoo yog muaj zog. Vim hais tias ntawm lawv cov cheeb tsam loj loj thiab deg adsorption thiab lwm yam, tshem tawm qhov ruaj khov colloidal tsis yooj yim rau adsorption mus rau diatomite, thiab adhesion ntawm diatomite particles ntawm cov kuab paug nyob rau hauv kev sib nrig sib adsorption muaj peev xwm loj, yog li refined hloov diatomite yog siv rau kev kho dej, sai sai tsim loj flocs thiab stability, granular flocs. Txawm tias thaum cov flocs tau tawg, kuj tuaj yeem tshwm sim dua flocculation. Filter pab yog qhov no lwm yam txhuas ntsev, hlau ntsev, xws li cov dej khib nyiab ntawm flocculant tsis tuaj yeem ncav cuag, diatomite loj tshwj xeeb nto, muaj zog adsorption thiab cov hluav taws xob hluav taws xob, ua rau nws nyob rau hauv cov txheej txheem ntawm kev kho dej, tsis tsuas yog tshem tawm cov roj hmab particle lub xeev thiab lub cev ntawm cov pa phem, thiab muaj peev xwm tshem tawm chromaticity thiab muaj nyob rau hauv yaj phosphorus (ib qho ntawm cov hlau, thiab lwm yam).
