Cov flocculant ua haujlwm li cas hauv kev kho dej?

FlocculantsUa si ib lub luag haujlwm tseem ceeb hauv kev kho dej los ntawm kev pab hauv kev tshem tawm ntawm cov ntawv raug tshem tawm thiab colloids los ntawm dej. Cov txheej txheem cuam tshuam nrog kev tsim cov flocs loj uas tuaj yeem daws tau lossis muab cov khoom tawg yooj yim. Ntawm no yog li cas flocculants ua haujlwm hauv kev kho dej: 

Flocculants yog tshuaj lom neeg ntxiv rau dej los pab txhawb kev sib cav ntawm cov me me, yooj yim tshem tawm cov roj teeb tau hu ua flocs.

Hom Flocculants suav nrog cov coorganic co coomulants zoo liPolymeric Aluminium Chloride(Pac) Thiab ferric chloride, ntxiv rau organic polymients flocculants uas tuaj yeem yog cov hluavtaws polymers xws li polyacrylamide lossis ntuj cov tshuaj xws li Chitosan.

Sib pauv:

Ua ntej flocculation, feem ntau yog cov tuaj yeem raug ntxiv rau txoj kev ua kom zoo colloidal hais. Caus yog nruab nrab nruab nrab ntawm cov nqi hluav taws xob ntawm cov me me, tso cai rau lawv tuaj ua ke.

Kev Coululants ib txwm muaj xws li polymeric txhuas chloride, txhuas sulfate (Alum) thiab ferric chloride.

Flocculation:

Flocculants tau ntxiv tom qab coagulation los txhawb kom muaj kev tsim cov flocs loj dua.

Cov tshuaj no sib cuam tshuam nrog cov khoom siv ua kom zoo, ua rau lawv tuaj ua ke thiab daim ntawv loj dua, pom kev sib xyaw.

Floc tsim:

Lub flocculation txheej txheem tshwm sim hauv kev tsim cov neeg loj thiab hnyav uas nyob ze sai vim nce ntxiv.

Floc tsim kuj tseem AIDS hauv kev nkag ntawm impurities, suav nrog cov khib nyiab, thiab lwm yam paug.

Tswm thiab qhia meej:

Thaum cov flocs tau tsim, cov dej tau tso cai rau khom nyob rau hauv ib tug sedimentation phiab.

Thaum lub sij hawm daws, flocs khom mus rau hauv qab, tawm hauv dej kom meej saum toj no.

Pom:

Rau kev ua kom huv ntxiv, cov dej kom meej yuav raug pom kom pom kev kom tshem tawm ib qho zoo uas tsis tau daws.

Tshuaj tua kab mob:

Tom qab flocculation, kev sib cais, cov dej yog feem ntau kho nrog cov tshuaj tua kab mob xws li chlorine los tshem tawm cov kab mob ntxiv thiab ua kom muaj kev nyab xeeb rau kev nyab xeeb.

Hauv cov ntsiab lus, cov nplaim taws ua haujlwm los ntawm nruab nrab ntawm kev txwv tsis pub siv cov khoom me me, tsim kom muaj qhov loj me me, ua rau muaj kev tshem tawm yooj yim thiab dej nqus tsev ntxhua khaub ncaws.
