Ntuj Zeolite lim xov xwm lim dej kho dej
Qhia txog Zeolite lim media
Zeolite lim xov xwm yog ua los ntawm cov khoom zoo zeolite ore, ua kom huv thiab granulated. Nws muaj cov haujlwm ntawm adsorption, pom thiab deodorization. Nws tuaj yeem siv los ua lub tshuab ua kom huv thiab ua kom zoo tshaj plaws, thiab lwm yam, thiab tau siv dav hauv kev kho dej, tsim cov av ntub, kho dej phwj tuaj, aquaculture.
Cov yam ntxwv zeolite
Zeolite muaj cov yam ntxwv ntawm kev nqus, hloov pauv ion, catalysis, thermal stability thiab acid thiab alkali tsis kam. Thaum siv hauv kev kho dej, zeolite tuaj yeem siv tsis tau tsuas yog siv nws cov adsorption, hloov pauv ion thiab lwm yam khoom, tab sis kuj tseem txo qis kev kho dej Tus nqi yog cov khoom lim zoo heev rau kev kho dej.
2.Zeolite lim xov xwm ua haujlwm
A: Tshem tawm ntawm ammonia nitrogen thiab phosphorus:
Zeolite muaj ntau yam kev siv hauv kev kho dej. Ntawm lawv, kev siv dav tshaj plaws yog nws lub peev xwm tshem tawm nitrogen thiab ammonia, thiab nws lub peev xwm tshem tawm phosphorus yog vim nws muaj peev xwm nqus tau zoo. Zeolite feem ntau siv rau hauv kev kho cov dej eutrophic, thiab zeolite haum kuj tseem tuaj yeem xaiv los ua cov muab tshuaj hauv kev kho cov av, uas tsis yog tsuas yog daws qhov kev tswj hwm tus nqi ntim khoom, tab sis kuj tseem siv tau cov av ntub dej muaj peev xwm tshem tawm cov tshuaj phem. Ib qho ntxiv, zeolite kuj tseem tuaj yeem siv los tshem tawm cov nitrogen thiab phosphorus los ntawm cov sludge.
B: Tshem tawm cov hlau hnyav ions:
Kev hloov kho zeolite muaj kev tshem tawm zoo dua ntawm cov hlau hnyav. Kev hloov zeolite tuaj yeem nqus tau cov hmoov lead, zinc, cadmium, npib tsib xee, tooj liab, cesium, thiab strontium hauv cov dej phwj tuaj. Cov hlau hnyav ions adsorbed thiab sib pauv los ntawm zeolite tuaj yeem mob siab rau thiab rov zoo. Ib qho ntxiv, zeolite siv los tshem cov hlau hnyav ions tuaj yeem siv tau tom qab kho tas. Piv nrog rau cov txheej txheem txheej txheem hlau hnyav, zeolite muaj qhov zoo ntawm kev muaj peev xwm ua tau loj thiab ua tus nqi qis.
C: Tshem tawm cov kuab paug organic:
Lub peev xwm nqus tau zeolite tuaj yeem tsis tsuas yog nqus cov ammonia nitrogen thiab phosphorus hauv dej, tab sis tseem tshem tawm cov pa phem hauv dej mus rau qee yam. Zeolite tuaj yeem kho cov kab mob sib kis hauv cov dej phwj tuaj, suav nrog cov pa phem ib txwm muaj xws li phenols, anilines, thiab amino acids. Ib qho ntxiv, cov pa roj carbon activated tuaj yeem siv ua ke nrog zeolite txhawm rau txhim kho nws lub peev xwm tshem tawm cov organic hauv dej.
D: Tshem tawm cov tshuaj fluoride hauv cov dej haus:
Xyoo tsis ntev los no, cov ntsiab lus siab ntawm cov tshuaj fluorine hauv cov dej haus tau nyiam ntau thiab ntau dua. Kev siv zeolite los kho cov dej uas muaj cov tshuaj fluorine tuaj yeem ncav cuag tus qauv dej haus, thiab cov txheej txheem yog yooj yim, kev kho mob tau ruaj khov, thiab tus nqi kho mob tsawg.
E: Tshem tawm cov khoom siv hluav taws xob:
Kev sib pauv ion ntawm zeolite tuaj yeem siv los tshem tawm cov tshuaj muaj kuab lom hauv dej. Tom qab zeolite sib pauv nrog cov ions hluav taws xob tau yaj, cov hluav taws xob ions tuaj yeem kho tau hauv lub lattice siv lead ua, yog li tiv thaiv kev rov kis kab mob ntawm cov khoom siv hluav taws xob.
Qhov zoo ntawm zeolite lim media
Zeolite lim xov xwm tau siv hauv kev kho dej thiab muaj qhov zoo hauv qab no:
(1) Nws tsis qab thiab tsis ua rau muaj kev cuam tshuam ib puag ncig;
(2) Tus nqi pheej yig;
(3) Acid thiab alkali tsis kam;
(4) Zoo thermal stability;
(5) Kev ua haujlwm tshem tawm cov pa phem yog ruaj khov thiab ntseeg tau;
(6) Nws muaj lub luag haujlwm los kho cov dej tsis huv uas muaj kuab paug;
(7) Nws yog qhov yooj yim rov tsim dua tom qab ua tsis tiav thiab tuaj yeem rov ua dua tshiab.
Kev qhia tshwj xeeb: 0.5-2mm, 2-5mm, 5-13mm, 1-2cm, 2-5cm, 4-8cm.
