Zeolite siv rau kev lag luam

1. Clinoptilolite

Clinoptilolite nyob rau hauv cov qauv compact ntawm pob zeb feem ntau yog nyob rau hauv lub micro zoo li ntawm radial phaj sib dhos, thaum nyob rau hauv qhov chaw uas cov pores tau tsim, phaj siv lead ua ke nrog cov duab geometric zoo li qub lossis ib nrab zoo li qub tuaj yeem tsim, uas tuaj yeem ua tau txog li 20mm dav thiab 5mm tuab, nrog lub kaum sab xis ntawm txog 120 degrees ntawm qhov kawg, thiab qee qhov ntawm lawv yog nyob rau hauv cov duab ntawm pob zeb diamond phaj thiab strips. Lub EDX spectrum muaj Si, Al, Na, K, thiab Ca.

2. Mordenite

Tus qauv microstructure ntawm SEM yog fibrous, nrog rau cov duab ncaj lossis me ntsis nkhaus, nrog rau txoj kab uas hla ntawm kwv yees li 0.2 hli thiab ntev ntawm ntau hli. Nws tuaj yeem yog cov pob zeb authigenic, tab sis nws kuj tuaj yeem pom ntawm ntug sab nraud ntawm cov pob zeb hloov pauv, maj mam sib cais mus rau hauv filamentous zeolite hauv cov duab radial. Hom zeolite no yuav tsum yog cov pob zeb hloov pauv. EDX spectrum feem ntau yog tsim los ntawm Si, Al, Ca, thiab Na.

3. Calcite

Cov qauv microstructure ntawm SEM muaj cov tetragonal triaoctahedra thiab ntau yam polymorphs, nrog rau cov dav hlau siv lead ua feem ntau tshwm sim ua 4 lossis 6 sab duab. Qhov loj ntawm cov noob tuaj yeem ncav cuag ntau kaum tawm hli. EDX spectrum muaj cov ntsiab lus ntawm Si, Al, Na, thiab tej zaum yuav muaj me ntsis Ca.

zeolite

Muaj ntau hom, thiab 36 hom twb tau tshawb pom lawm. Lawv qhov tshwj xeeb yog tias lawv muaj cov qauv zoo li scaffold, uas txhais tau tias hauv lawv cov siv lead ua, cov molecules txuas ua ke zoo li scaffold, tsim ntau qhov hauv nruab nrab. Vim tias tseem muaj ntau cov dej molecules hauv cov qhov no, lawv yog cov minerals hydrated. Cov dej noo no yuav raug tso tawm thaum raug rau qhov kub siab, xws li thaum hlawv nrog nplaim taws, feem ntau cov zeolites yuav nthuav dav thiab ua npuas dej, zoo li npau. Lub npe zeolite los ntawm qhov no. Cov zeolites sib txawv muaj ntau hom, xws li zeolite thiab zeolite, uas feem ntau yog cov siv lead ua axial, zeolite thiab zeolite, uas zoo li phaj, thiab zeolite, uas zoo li koob lossis fibrous. Yog tias ntau yam zeolites yog ntshiab sab hauv, lawv yuav tsum tsis muaj xim lossis dawb, tab sis yog tias lwm yam impurities sib xyaw sab hauv, lawv yuav qhia ntau yam xim kaj. Zeolite kuj muaj lub teeb ci ntsa iab. Peb paub tias dej hauv zeolite tuaj yeem khiav tawm, tab sis qhov no tsis ua rau puas tsuaj rau cov qauv siv lead ua hauv zeolite. Yog li ntawd, nws kuj tuaj yeem rov nqus dej lossis lwm yam kua. Yog li, qhov no kuj tau dhau los ua ib qho yam ntxwv ntawm cov neeg siv zeolite. Peb tuaj yeem siv zeolite los cais qee yam khoom tsim tawm thaum lub sijhawm ua kom huv, uas tuaj yeem ua rau huab cua qhuav, nqus tau qee yam pa phem, ntxuav thiab qhuav cawv, thiab lwm yam.

Zeolite muaj cov yam ntxwv xws li kev nqus, kev pauv ion, catalysis, acid thiab cua sov tsis kam, thiab siv dav ua tus adsorbent, tus neeg sawv cev pauv ion, thiab catalyst. Nws kuj tseem siv tau rau hauv kev ziab roj, kev ntxuav, thiab kev kho dej khib nyiab. Zeolite kuj muaj txiaj ntsig zoo rau kev noj haus. Ntxiv 5% zeolite hmoov rau hauv pub tuaj yeem ua kom cov nqaij qaib thiab tsiaj txhu loj hlob sai dua, ua rau lawv muaj zog thiab tshiab, thiab muaj qe ntau lawm.

Vim yog cov khoom silicate porous ntawm zeolite, muaj qee qhov cua nyob rau hauv cov qhov me me, uas feem ntau siv los tiv thaiv kev npau. Thaum lub sijhawm cua sov, huab cua hauv lub qhov me me tawm mus, ua haujlwm ua lub hauv paus roj, thiab cov npuas me me yooj yim tsim ntawm lawv cov npoo thiab ces kaum.

Hauv kev ua liaj ua teb hauv dej

1. Ua ib qho khoom noj ntxiv rau ntses, cw, thiab cw. Zeolite muaj ntau yam khoom tsis tu ncua thiab cov khoom me me uas tsim nyog rau kev loj hlob thiab kev txhim kho ntawm ntses, cw, thiab cw. Cov khoom no feem ntau muaj nyob rau hauv cov xeev ion pauv tau thiab cov ntsev soluble, uas yooj yim nqus thiab siv. Tib lub sijhawm, lawv kuj muaj ntau yam teebmeem catalytic ntawm cov enzymes biological. Yog li ntawd, kev siv zeolite hauv ntses, cw, thiab cw pub muaj cov teebmeem ntawm kev txhawb nqa metabolism, txhawb kev loj hlob, txhim kho kev tiv thaiv kab mob, txhim kho tus nqi ciaj sia, tswj cov kua dej hauv lub cev tsiaj thiab osmotic siab, tswj cov kua qaub-puag sib npaug, ntxuav cov dej zoo, thiab muaj qee yam ntawm cov nyhuv tiv thaiv pwm. Tus nqi ntawm cov hmoov zeolite siv rau hauv ntses, cw, thiab cw pub feem ntau yog ntawm 3% thiab 5%.

2. Ua ib tug neeg sawv cev kho dej zoo. Zeolite muaj kev nqus dej tshwj xeeb, kev tshuaj ntsuam, kev sib pauv ntawm cov cations thiab anions, thiab kev ua haujlwm catalytic vim nws muaj ntau qhov loj me, cov qhov dej sib xws, thiab cov qhov dej loj sab hauv. Nws tuaj yeem nqus cov ammonia nitrogen, cov organic matter, thiab cov hlau hnyav hauv dej, txo cov tshuaj lom ntawm hydrogen sulfide hauv qab pas dej, tswj pH, ua rau cov pa oxygen yaj hauv dej, muab cov pa roj carbon txaus rau kev loj hlob ntawm phytoplankton, txhim kho qhov muaj zog ntawm cov dej photosynthesis, thiab kuj yog ib qho chiv zoo. Txhua kilogram ntawm zeolite siv rau hauv pas dej nuv ntses tuaj yeem coj 200 milliliters ntawm oxygen, uas maj mam tso tawm hauv daim ntawv ntawm microbubbles kom tiv thaiv kev puas tsuaj ntawm dej thiab ntses los ntawm kev ntab. Thaum siv cov hmoov zeolite ua cov tshuaj txhim kho dej zoo, cov koob tshuaj yuav tsum tau siv ntawm qhov tob ntawm dej ib 'meter' ib acre, ntxiv rau kwv yees li 13 kilograms, thiab muab tshuaj rau thoob plaws hauv pas dej.

3. Siv ua cov khoom siv rau kev tsim cov pas dej nuv ntses. Zeolite muaj ntau lub qhov hws sab hauv thiab muaj peev xwm nqus tau zoo heev. Thaum kho cov pas dej nuv ntses, tib neeg tso tseg txoj kev coj ua ib txwm siv xuab zeb daj los tso rau hauv qab ntawm lub pas dej. Hloov chaw, xuab zeb daj raug tso rau ntawm txheej hauv qab, thiab cov pob zeb npau nrog lub peev xwm pauv anions thiab cations thiab nqus cov tshuaj lom hauv dej raug tawg rau ntawm txheej sab saud. Qhov no tuaj yeem ua kom xim ntawm lub pas dej nuv ntses ntsuab lossis daj ntsuab txhua xyoo puag ncig, txhawb kev loj hlob sai thiab noj qab haus huv ntawm cov ntses, thiab txhim kho cov txiaj ntsig kev lag luam ntawm kev ua liaj ua teb aquaculture.
