Cov ntaub ntawv no muab kwv yees kwv yees kwv yees thiab tshuaj ntau ntawm cov hom phiaj dej sib txawv, lawv yuav tsum tau txiav txim siab raws li kev sim ua kom zoo thiab kev sim ua ntej.
3. ferric chloride
Cov nyiaj ntawm daim ntawv thov: Haum rau dej phwj uas muaj cov hlau hnyav ions .
Dosage piv: Feem ntau 10-50 mg / l .
Kev ntsuas kev ntsuas: Cov ntsiab lus ntawm FE2O3, qhov txiaj ntsig zoo ntawm Ferric chloride, yuav tsum yog saum 30% .
Cov Lus Qhia Ua Haujlwm: Ferric chloride yuav tsum tau ua tiav tag nrho, thiab lub ntsiab lus xaus yog feem ntau {% {2}.
Flocculant Dosage piv
Flocculants feem ntau yog siv los txhim kho cov txiaj ntsig sib txawv ....}}}} Feem ntau siv flocc
1. polyacrylamide (PAM)

Dosage piv: Feem ntau 3 mg / l (rau txhua 1 mg / l ntawm nitrate tshem tawm) .
Kev ntsuas kev ua haujlwm: lub laj thawj ntawm methanol yuav tsum yog saum 99% .
Cov Lus Qhia Txog Cov Nyiaj Ua Haujlwm
Tswv yim ua haujlwm cov tswv yim
1.}} kev xaus thiab cia ntawm reagents
- lub reagent yuav tsum tau ua tiav tag nrho ua ntej siv, thiab lub sijhawm sib cais thiab kev xav tau raws li cov yam ntxwv ntawm cov reagent .
