Tam sim no, muaj ntau txoj hauv kev los kho cov tshuaj fluoride ntau huv yog siv rau kev kho cov dej haus cawv uas yog siv rau kev noj haus dej haus, Khov, ion txauv, ultrarafiltration defluorination, electrocoagulation, electrocoagulation, electrocoagulation, hloov osmosissis, rov qab .
1.} nag lossis daus nag lossis daus
Nag lossis daus yog ib txoj kev siv ntau tshaj plaws rau kev kho fluoride los ntawm kev rho tawm dej nag lossis cov tshuaj lom neeg, thiab ua tiav cov tshuaj tiv thaiv fluoride} Nas Hau Zog .
2. Tus Qauv Tshuaj Zej Zog
Tshuaj lom neeg nag lossis daus yog siv rau kev kho mob fluoride hos los ua cov tshuaj pleev kom muaj calcium los ntawm kev ua kom tiav lub hom phiaj ntawm kev tshem tawm cov Wastewater . Cov txheej txheem yooj yim thiab yooj yim {} Yog yog li muaj qee yam kev kho tshuaj fluoride nyob rau hauv kev kho cov tshuaj fluoride mus txog ntawm kev saib xyuas cov tshuaj fluoride Thiab nws yog qhov nyuaj kom tau raws li lub teb chaws tus qauv rau thawj qib. prepmented nyob rau saum npoo ntawm CA (Huag)
Nyob rau hauv xyoo tsis ntev los no, qee cov kws tshaj lij tau ua ntau cov kev tshawb fawb ntawm kev ntxiv cov khoom siv roj ntsha, ntawm cov ntsev fluoride ntxiv, thiab cov kua qaub thiab cov aucel daws muaj cov ntsev magnesium kom tsim cov tshuaj tua kab mob fluoride kom ua rau cov kab mob fluoride Ua kom muaj cov khoom siv tshuaj pleev kom zoo nkauj, muaj cov roj ntsha tau ntxiv rau cov khoom siv pov tseg thiab cov roj ntsha tau ntxiv yam tsis muaj cov cuab yeej siv thiab kho khoom .
{{0 {}} co coagulation thiab sedimentation txoj kev
Cov txheej txheem sib xyaw thiab kev ua kom zoo yog ntxiv ob hom coagulan thiab alentsle} Cov txheej txheem fluently thiab aluminium kom ua tiav rau kev kho fluoride tsawg wastewater . Nws yog feem ntau siv rau kev kho mob fluoride thiab nag los, lub sijhawm effringation zoo yuav tsis ruaj khov txaus.
Cov tshuaj ntsuab ntawm cov hlau Coagulants feem ntau yuav tsum tau siv ua ke nrog Ca (Oh), yog li cov txheej txheem aluminium water, and use the complexation of Al3+ and F- and the Al(OH)3 alum produced after the hydrolysis of aluminum salts to remove F- in the wastewater, with good results. Aluminum salt coagulation and sedimentation method is widely used in industrial wastewater treatment due to the small amount of reagents added, low cost, and the effluent can meet the national emission standards after one kev kho .
4.} cov qauv adsorption
Cov qauv adsorption yog kom muab cov khoom siv hluav taws xob xws li ua kom zoo nkauj, ua kom cov roj ntsha adsorbent, ua haujlwm fluorbent, actical ras hloov pauv nrog cov khoom siv hluav taws xob, thiab thaum kawg adsorbed ntawm Adsorbent . Tus adsorbent tseem tuaj yeem tswj tau cov kev kho mob kom ntseeg tau, feem ntau yog cov kev kho mob siab tshaj plaws. Cov qauv no feem ntau yog siv rau kev kho mob qis-siab fluoride-muaj dej khib nyiab, thiab cov nyhuv yog qhov tseem ceeb heev . Vim nws muaj tus nqi qis thiab cov tshuaj fluoride uas muaj pov tseg kom huv si.}}
5. lwm txoj hauv kev
Ntxiv rau cov txheej txheem saum toj no, muaj qee cov kev siv tshuaj lom zem, tab sis tau ua tiav cov tshuaj lom neeg tshwj xeeb, thim rov qab osmosity Technology siv ntau dua li osmotic siab Txhawm rau hloov cov kab mob osmules hauv cov dej roj fluoride thiab hloov kho cov dej rov qab muaj xws li cov tshuaj txhuam hniav os Week Electrodialysis yog ib txoj kev sib pauv ntawm cov kab mob fluoride}} ion txauv cov resins yuav tsum tau ua etreated thiab rov ua dua nrog aluminium ntsev, yog li tus nqi yuav tsis muaj nqi, thiab muaj kev sib pauv hloov pauv, tab sis muaj kev tu cov txiaj ntsig rau lub cev, tab sis muaj kev sib pauv khoom noj kom zoo, tab sis yuav tsis muaj kev kho kom zoo dua qub txoj kev rau kev tshem tawm kom tob ntawm fluoride ions hauv dej .
