Cov ntaub ntawv sib txawv ntawm cov hlau sulfide, xws li pyrite (FeS?) thiab mackinawite (FeS), muaj ntau yam kev hloov pauv, cuam tshuam rau kev xaiv cov txheej txheem tshem tawm.

Qhov chaw ntawm Iron Sulfide Contamination

Cov kab mob hlau sulfide tuaj yeem tshwm sim los ntawm ntau qhov chaw, suav nrog cov minerals tshwm sim hauv cov av thiab pob zeb tsim, cov txheej txheem kev lag luam uas muaj leej faj, thiab txawm tias cov txheej txheem lom neeg. Kev nkag siab txog qhov chaw yog qhov tseem ceeb rau kev tsim kom muaj txiaj ntsig zoo hlau sulfide tshem tawm tswv yim. Piv txwv li, hauv cov chaw kho dej khib nyiab, hlau sulfide tuaj yeem tsim los ntawm kev tawg ntawm cov organic teeb meem nyob rau hauv cov xwm txheej anaerobic. Hauv kev mining, pyrite, ib hom hlau sulfide ntxhia, feem ntau yog cov khoom ntawm ore rho tawm.

Txoj kev rau Iron Sulfide Tshem Tawm

Txoj kev kho tshuaj

Tshuaj oxidation yog ib txoj hauv kev zoo rau hlau sulfide tshem tawm. Oxidizing cov neeg ua haujlwm, xws li chlorine, ozone, thiab hydrogen peroxide, hnov ​​​​mob nrog hlau sulfide, hloov nws mus rau hauv cov teeb meem tsis tshua muaj hlau oxides thiab sulfates. Kev xaiv ntawm oxidant nyob ntawm yam xws li tus nqi, kev ua tau zoo, thiab muaj peev xwm cuam tshuam ib puag ncig. Piv txwv li, chlorine muaj txiaj ntsig zoo tab sis tuaj yeem tsim cov khoom tsim kev puas tsuaj. Ozone yog qhov muaj zog oxidant, tab sis nws kim dua. Ua tib zoo xav txog cov ntawv thov tshwj xeeb thiab nws cov kev txwv yog qhov tseem ceeb.

Txoj kev tshem tawm lub cev

Kev siv lub cev, xws li kev pom thiab kev ua kom cov av qis, tuaj yeem ua haujlwm kom tshem tawm cov khoom hlau sulfide los ntawm dej los yog lwm yam dej. Cov tswv yim pom, suav nrog cov xuab zeb pom, membrane pom, thiab cov pa roj carbon adsorption, tuaj yeem cais cov hlau sulfide los ntawm cov kua dej zoo. Kev xaiv ntawm txoj kev pom zoo yog nyob ntawm qhov loj thiab qhov concentration ntawm cov khoom thiab qhov xav tau ntawm kev lim dej. Sedimentation yog ib txoj kev yooj yim dua thiab tsis tshua muaj zog-intensive txoj kev tsim nyog rau tshem tawm cov khoom loj dua uas tawm ntawm kev ncua.

Cov txheej txheem lom neeg

Biologically mediated hlau sulfide tshem tawm Nws suav nrog kev siv cov kab mob oxidize hlau sulfide. Txoj kev no muaj kev ruaj ntseg thiab ib puag ncig zoo rau kev kho tshuaj. Qee cov kab mob tuaj yeem ua tau zoo oxidize hlau sulfide, hloov nws mus rau hauv cov ntaub ntawv tsis zoo. Txawm li cas los xij, txoj kev no feem ntau xav tau ib puag ncig tshwj xeeb thiab tuaj yeem ua qeeb dua tshuaj oxidation.

Xaiv txoj cai hlau Sulfide tshem tawm cov txheej txheem

Qhov zoo hlau sulfide tshem tawm txoj kev nyob ntawm ob peb yam, nrog rau cov concentration ntawm hlau sulfide, hom hlau sulfide tam sim no, lub siab xav tau ntawm purification, thiab cov nqi txiav txim siab. Kev ntsuam xyuas tag nrho ntawm cov xwm txheej no yog qhov tseem ceeb ua ntej xaiv cov txheej txheem tshwj xeeb. Feem ntau, kev sib xyaw ua ke ua pov thawj zoo tshaj plaws.

Case Studies thiab Kev Ua Zoo Tshaj Plaws

Ob peb cov ntaub ntawv kawm tau zoo qhia tau hais tias kev ua tau zoo ntawm qhov sib txawv hlau sulfide tshem tawm cov tswv yim hauv ntau qhov kev lag luam.
