Dab tsi yog ferric chloride siv rau hauv kev kho dej?

Ferric chlorideyog cov tshuaj sib txuas nrog cov mis fecl3. Nws yog dav siv nyob rau hauv cov txheej txheem dej kho mob ua ib qho kev ua kom zoo rau kev tshem tawm cov dej tsis zoo thiab tsis zoo hauv dej txias dua li alum. Kwv yees li 93% ntawm Ferric chloride yog siv hauv kev kho dej, piv txwv li cov dej khib nyiab, dej phwj tuaj thiab dej haus. Ferric chloride feem ntau yog siv nyob rau hauv daim ntawv foos raws li kev daws teeb meem rau dej thiab khib nyiab.

Daim ntawv thov ntawm ferric chloride hauv kev kho dej:

1. Kev siv flocculation: ib qho ntawm thawj cov siv ntawm ferric chloride hauv kev kho cov dej yog ua ib tug coagulant. Thaum ntxiv rau dej, ferric chloride reacts nrog cov dej ferric hydroxide thiab lwm yam impurities, thiab lwm yam impurities los tsim cov khoom loj, cov khoom hnyav hu ua flocs. Cov flocs no tuaj yeem txiav txim siab tau yooj yim dua thaum lub sijhawm ua kom tiav lossis cov txheej txheem pom, tso cai rau kev tshem tawm ntawm cov dej tsis huv.

2. Phosphorus tshem tawm: Ferric chloride yog siv tau tshwj xeeb hauv kev tshem tawm phosphorus ntawm dej. Phosphorus yog ib qho khoom noj muaj txiaj ntsig pom hauv cov dej khib nyiab, thiab cov qib ntau dhau los tuaj yeem ua rau Eutsroudicication hauv kev tau txais cov kua dej. Ferric chloride cov ntawv insoluble complex nrog phosphorus, uas tuaj yeem tshem tawm los ntawm nag lossis lim, pab txo kom txo cov dej phosphorus rau hauv dej.

3. Hnyav Hlau Tshem Tawm: Ferric Chloride tseem siv los tshem cov hlau hnyav, xws li arsenic, txhuas, thiab mercury, los ntawm dej. Cov hlau no tuaj yeem lom tau heev thiab ua rau muaj kev pheej hmoo txaus ntshai yog tias muaj nyob hauv dej haus. Ferric chloride cov ntaub ntawv insoluble hlau hydroxides lossis cov hlau tshem tawm, uas tuaj yeem raug tshem tawm cov txheej txheem hnyav ntawm cov dej.

4. Xim thiab ODOR kev tshem tawm: Ferric chloride muaj txiaj ntsig hauv kev tshem cov xim thiab tsw qab los ntawm dej. Nws oxidizes cov kab paus organic rau cov xim uas muaj lub luag haujlwm rau cov xim thiab tsw, tsoo lawv mus rau hauv me me, tsawg tsis pom zoo cov tshuaj. Cov txheej txheem no yuav pab txhim kho kom zoo nkauj ntawm dej, ua rau nws haum ntau rau kev haus, kev lag luam, lossis lub hom phiaj ua si.

5. Kev hloov kho: los ntawm kev tswj hwm lub ph, ferric chloride tuaj yeem ua kom tiav ntawm lwm yam kev kho mob, floagulation, flocculation, thiab tshuaj tua kab mob. Cov Phos Phos Yeem Pauv yuav pab tsim cov kev cai zoo rau kev tshem tawm ntawm impurities thiab paug los ntawm dej.

6. Kev kho mob los ntawm kev tswj hwm los ntawm kev tswj hwm: Ferric chloride tuaj yeem pab tswj kev tsim ntawm kev rho tawm cov tshuaj tua kab mob (DBPS) thaum kho dej. Thaum siv nrog cov tshuaj tua kab mob xws li cov tshuaj chlorine, ferric chloride tuaj yeem txo qhov kev tsim ntawm DMPS xws li Treihalomethanes (thoas) thiab muaj peev xwm), uas yog carcinogens. Qhov no pab tau tag nrho kev nyab xeeb thiab kev ua haujlwm ntawm cov dej haus.

7. Sludge dewatering: Ferric chloride kuj tseem siv nyob rau hauv sludge deedatering cov txheej txheem hauv cov nroj tsuag tsis siv dej. Nws pab kom muaj kev cuam tshuam cov sludge los ntawm kev txhawb nqa kev tsim ntawm loj dua, denser flocs, uas nyob ze sai thiab tso dej ntau dua. Qhov no ua rau kev txhim kho dewatering kev ua tau zoo thiab txo cov sludge ntim, ua rau nws yooj yim dua los daws thiab muab pov tseg ntawm cov sludge.

Ferric chloride plays lub luag haujlwm tseem ceeb hauv kev kho dej, suav nrog kev tshem tawm cov xim, ua kom tsis txhob muaj zog, phua kho tshuaj tua kab, thiab sludge dewatering. Nws cov versatility thiab cov txiaj ntsig ua rau nws muaj txiaj ntsig zoo rau kev kho cov dej ntawm ob qho dej haus thiab dej khib nyiab, pab kom muaj kev nyab xeeb, kev ua tau zoo, thiab muaj peev xwm ntawm cov khoom siv dej.
