Nrog rau cov kev cai tiv thaiv ib puag ncig uas nruj zuj zus thiab qhov nyuaj ntawm kev kho cov dej khib nyiab hauv kev lag luam, polydimethyldiallylammonium chloride (PDADMAC, cov mis tshuaj: [(C₈H₁₆NCl)ₙ])(https://www.cleanwat.com/poly-dadmac/)tab tom dhau los ua ib yam khoom tseem ceeb. Nws cov yam ntxwv ua kom cov dej sib xyaw ua ke zoo, kev siv tau, thiab kev phooj ywg ib puag ncig tau ua rau nws siv dav hauv kev ntxuav dej thiab kev kho dej khib nyiab.
Kev Taw Qhia Txog Khoom
Cov polymer muaj cov pab pawg cationic muaj zog thiab cov pab pawg adsorbent nquag. Los ntawm kev tshem tawm cov nqi thiab kev sib txuas adsorption, nws ua rau cov khoom me me thiab cov tshuaj yaj hauv dej uas muaj cov pab pawg tsis muaj nqi hauv dej tsis ruaj khov thiab ua rau cov khoom me me thiab cov tshuaj yaj hauv dej tsis ruaj khov, qhia tau tias muaj txiaj ntsig zoo hauv kev tshem tawm xim, ua kom tsis muaj menyuam, thiab tshem tawm cov organic. Cov khoom no xav tau tsawg kawg nkaus, tsim cov flocs loj, sai sai poob, thiab tsim cov turbidity seem tsawg kawg nkaus, ua rau muaj sludge tsawg kawg nkaus. Nws kuj ua haujlwm hauv pH ntau ntawm 4-10. Nws tsis muaj ntxhiab, tsis muaj saj, thiab tsis muaj tshuaj lom, ua rau nws haum rau ntau yam kev ntxuav dej thiab kev kho dej khib nyiab.
Cov Lus Qhia Txog Kev Zoo
| Qauv | CW-41 |
| Qhov tsos | Lub teeb rau daj ntseg, pob tshab, kua nplaum. |
| Cov khoom khov (%) | ≥40 |
| Qhov khov (mPa.s, 25°C) | 1000-400,000 |
| pH (1% kua dej) | 3.0-8.0 |
| Lus Cim: Cov khoom uas muaj cov khoom khov thiab viscosities sib txawv tuaj yeem hloov kho raws li qhov kev thov. | |
Kev Siv
Thaum siv ib leeg xwb, yuav tsum npaj cov tshuaj uas yaj tau. Qhov concentration feem ntau yog 0.5% -5% (nyob ntawm cov khoom khov).
Thaum kho cov dej thiab cov dej khib nyiab sib txawv, qhov ntau npaum li cas yuav tsum tau txiav txim siab raws li qhov turbidity thiab concentration ntawm cov dej kho. Qhov ntau npaum li cas kawg tuaj yeem txiav txim siab los ntawm kev sim ua ntej.
Yuav tsum xaiv qhov chaw ntxiv thiab qhov ceev ntawm kev sib tov kom zoo kom sib xyaw nrog cov khoom siv thaum tsis txhob tawg cov floc.
Qhov kev ntxiv tas mus li yog qhov zoo dua.
Cov ntawv thov
Rau kev ntab dej, nws tuaj yeem txhim kho kev tsim khoom zoo dua thiab txo cov khoom pov tseg. Rau kev lim dej, nws tuaj yeem txhim kho cov dej lim zoo thiab txhim kho kev lim dej zoo.
Rau kev sib sau ua ke, nws tuaj yeem txhim kho kev ua haujlwm ntawm kev sib sau ua ke thiab ua kom cov dej ntws sai dua. Siv rau kev ua kom dej ntshiab, txo qhov SS tus nqi thiab qhov turbidity ntawm cov dej kho thiab txhim kho qhov zoo ntawm cov dej khib nyiab.
