Cov Yam Cuam Tshuam Rau Kev Ua Haujlwm Flocculant Hauv Kev Kho Dej Phwj

Hauv kev kho dej khib nyiab, pH yog ib qho tseem ceeb uas cuam tshuam ncaj qha rau qhov ua tau zoo ntawmCov tshuaj flocculantTsab xov xwm no piav qhia txog qhov cuam tshuam ntawm pH, alkalinity, kub, qhov loj ntawm cov khoom tsis huv, thiab hom flocculant rau kev ua haujlwm ntawm flocculation.

Kev cuam tshuam ntawm pH

Qhov pH ntawm cov dej khib nyiab muaj feem cuam tshuam nrog kev xaiv, kev siv tshuaj, thiab kev ua haujlwm ntawm cov tshuaj flocculants. Cov kev tshawb fawb qhia tau tias thaum pH qis dua 4, kev ua haujlwm ntawm cov tshuaj coagulation tsis zoo heev. Qhov no yuav yog vim muaj cov khoom me me uas tswj tau pH qis hauv cov dej khib nyiab, ua rau cov tshuaj flocculants nyuaj rau coagulate lawv. Thaum pH nyob nruab nrab ntawm 6.5 thiab 7.5, kev ua haujlwm ntawm cov tshuaj coagulation zoo dua vim tias qhov tsis ruaj khov ntawm cov khoom me me hauv pH no ua rau cov tshuaj flocculants ua haujlwm tau zoo dua. Txawm li cas los xij, thaum pH tshaj 8, kev ua haujlwm ntawm cov tshuaj coagulation poob qis, tej zaum vim tias pH siab hloov pauv qhov sib npaug ntawm cov ion hauv cov dej khib nyiab, cuam tshuam tsis zoo rau cov tshuaj flocculants.

Thaum pH qis dhau, PAC tsis tuaj yeem tsim cov flocs tau zoo, thiab cov pab pawg anionic ntawm APAM yuav raug neutralized, ua rau nws tsis ua haujlwm. Thaum pH siab dhau, PAC precipitates sai dhau, ua rau kev ua haujlwm tsis zoo, thiab CPAM yooj yim hydrolysis thiab ua tsis tau zoo.

Lub luag haujlwm ntawm Alkalinity

Qhov alkalinity ntawm cov dej phwj tuaj yeem ua rau pH tsis ruaj khov. Thaum cov dej phwj tsis txaus alkalinity, feem ntau yuav tsum tau ntxiv cov tshuaj xws li txiv qaub ntsuab kom tswj tau pH kom ruaj khov thiab txhim kho PAC qhov zoo tshaj plaws ntawm kev sib sau ua ke. Ntawm qhov tod tes, thaum pH ntawm dej siab dhau, tej zaum yuav tsum tau ntxiv cov kua qaub kom txo qhov pH kom nruab nrab, kom ntseeg tau tias cov tshuaj sib sau ua ke ua haujlwm tau zoo.

Kev Cuam Tshuam ntawm Kub

Qhov kub ntawm cov dej khib nyiab kuj yog ib qho tseem ceeb uas cuam tshuam rau qhov ua tau zoo ntawm kev ua kom cov dej khov loj. Thaum qhov kub qis, cov dej khib nyiab muaj viscosity siab, txo qhov zaus ntawm kev sib tsoo ntawm cov khoom me me thiab cov khoom tsis huv hauv dej, ua rau cov flocculants tsis sib txuas. Yog li ntawd, txawm tias nce cov tshuaj flocculants, kev ua kom cov dej khov loj tseem qeeb, ua rau cov qauv xoob thiab cov khoom me me uas nyuaj rau tshem tawm hauv qab qhov kub qis.

Kev Cuam Tshuam ntawm Qhov Loj ntawm Cov Khoom Uas Tsis Muaj Peev Xwm

Qhov loj thiab kev faib tawm ntawm cov khoom tsis huv hauv cov dej khib nyiab kuj tseem cuam tshuam rau qhov ua tau zoo ntawm kev ua kom cov dej khov loj. Cov khoom me me uas tsis sib xws lossis me dhau yuav ua rau cov dej khov tsis zoo vim tias cov khoom me me uas tsis huv feem ntau nyuaj rau sib sau ua ke zoo los ntawm cov tshuaj ua kom cov dej khov loj. Hauv cov xwm txheej zoo li no, kev rov qab los yog kev ntxiv cov tshuaj ua kom cov dej khov loj tuaj yeem ua rau cov dej khov loj dua.

Kev Xaiv Cov Hom Flocculant

Kev xaiv hom flocculant uas tsim nyog yog qhov tseem ceeb rau kev txhim kho kev kho dej khib nyiab kom zoo. Ntau hom flocculants, xws li inorganic flocculants, polymer flocculants, thiab activated silica gel, muaj lawv qhov zoo hauv ntau qhov xwm txheej. Piv txwv li, thaum cov khoom seem hauv cov dej khib nyiab muaj nyob rau hauv daim ntawv colloidal, inorganic flocculants feem ntau ua haujlwm tau zoo dua. Thaum cuam tshuam nrog cov khoom me me, ntxiv cov polymer flocculants lossis activated silica gel ua coagulants yuav tsim nyog. Hauv ntau qhov xwm txheej, kev siv ua ke ntawm inorganic thiab polymer flocculants tuaj yeem txhim kho kev ua haujlwm ntawm flocculation thiab nthuav dav ntawm qhov kev siv.

Cov yam xws li tus nqi pH, alkalinity, kub, qhov loj me ntawm cov khoom tsis huv, thiab hom dej khib nyiab ua ke cuam tshuam rau qhov ua tau zoo ntawm cov flocculants hauv kev kho dej khib nyiab. Kev nkag siab tob thiab kev tswj hwm ntawm cov yam no yog qhov tseem ceeb heev rau kev txhim kho qhov ua tau zoo ntawm kev kho dej khib nyiab. Peb yog koj tus neeg muab khoom siv tshuaj flocculant uas ntseeg tau, nrog ntau hom flocculants, suav nrog PAM, PAC, thiab lwm yam. Hauv peb lub vev xaib official koj tuaj yeem tshawb nrhiav peb cov khoom ntau yam yooj yim. Yog tias koj muaj lus nug lossis xav tau kev pab, thov koj xav tiv tauj peb!
