pH ntawm cov dej phwj tuaj
Tus nqi pH ntawm cov dej phwj tuaj yeem cuam tshuam loj heev rau cov nyhuv ntawm cov flocculants. Tus nqi pH ntawm cov dej phwj tuaj yeem cuam tshuam nrog kev xaiv cov hom flocculant, cov koob tshuaj ntawm cov flocculants thiab cov nyhuv ntawm coagulation thiab sedimentation. Thaum tus nqi pH yog<4, qhov coagulation effect tsis zoo heev. Thaum tus nqi pH yog nruab nrab ntawm 6.5 thiab 7.5, qhov coagulation effect zoo dua. Tom qab tus nqi pH>8, cov nyhuv coagulation ua rau tsis zoo dua.
Qhov alkalinity hauv cov dej phwj tuaj yeem ua rau muaj qhov cuam tshuam rau tus nqi PH. Thaum qhov alkalinity ntawm cov dej phwj tsis txaus, yuav tsum ntxiv cov kua qaub thiab lwm yam tshuaj lom neeg los ntxiv rau nws. Thaum tus nqi pH ntawm cov dej siab, nws yog qhov tsim nyog los ntxiv cov kua qaub los kho tus nqi pH kom nruab nrab. Qhov sib piv, cov polymer flocculants tsis tshua cuam tshuam los ntawm pH.
qhov kub ntawm cov dej phwj tuaj
Qhov kub ntawm cov dej phwj tuaj yeem cuam tshuam rau qhov ceev ntawm cov flocculant. Thaum cov dej phwj nyob rau ntawm qhov kub qis, qhov viscosity ntawm cov dej siab, thiab tus lej ntawm kev sib tsoo ntawm cov khoom me me flocculant thiab cov khoom tsis huv hauv dej raug txo qis, uas cuam tshuam kev sib txuas ntawm cov flocs; yog li ntawd, txawm hais tias cov koob tshuaj ntawm flocculants nce ntxiv, kev tsim cov flocs tseem qeeb, thiab nws xoob thiab zoo-grained, ua rau nws nyuaj rau tshem tawm.
cov impurities hauv cov dej phwj tuaj
Qhov loj me ntawm cov khoom tsis huv hauv cov dej phwj tuaj yeem pab txhawb kev sib sau ua ke, ntawm qhov tsis sib xws, cov khoom me me thiab sib xws yuav ua rau muaj kev sib sau ua ke tsis zoo. Kev sib sau ua ke tsawg dhau ntawm cov khoom tsis huv feem ntau ua rau muaj kev puas tsuaj rau kev sib sau ua ke. Lub sijhawm no, kev rov qab los ntawm cov av qias neeg lossis ntxiv cov khoom pab txhawb kev sib sau ua ke tuaj yeem txhim kho cov nyhuv sib sau ua ke.
Hom flocculants
Qhov kev xaiv ntawm cov flocculant feem ntau nyob ntawm qhov xwm txheej thiab qhov concentration ntawm cov khoom khov kho hauv cov dej phwj tuaj. Yog tias cov khoom khov kho hauv cov dej phwj tuaj zoo li gel, yuav tsum xaiv cov flocculants inorganic kom tsis ruaj khov thiab coagulate. Yog tias cov flocs me me, yuav tsum ntxiv cov polymer flocculants lossis siv cov khoom pab coagulation xws li activated silica gel.
Feem ntau, kev siv ua ke ntawm cov inorganic flocculants thiab polymer flocculants tuaj yeem txhim kho cov nyhuv coagulation thiab nthuav dav ntawm daim ntawv thov.
Dosage ntawm flocculant
Thaum siv cov tshuaj coagulation los kho cov dej khib nyiab, muaj cov tshuaj flocculants zoo tshaj plaws thiab cov koob tshuaj zoo tshaj plaws, uas feem ntau txiav txim siab los ntawm kev sim. Kev siv tshuaj ntau dhau yuav ua rau rov qab ruaj khov ntawm cov colloid.
Kev siv cov tshuaj flocculant ua ke
Thaum siv ntau yam flocculants, qhov kev ntsuas tshuaj zoo tshaj plaws yuav tsum tau txiav txim siab los ntawm kev sim. Feem ntau, thaum siv cov inorganic flocculants thiab cov organic flocculants ua ke, yuav tsum ntxiv cov inorganic flocculants ua ntej, thiab tom qab ntawd yuav tsum ntxiv cov organic flocculants.
