Yuav Siv Cov Tshuaj Kho Dej Li Cas 1

Tam sim no peb tau saib xyuas ntau dua rau kev kho cov dej khib nyiab thaum cov pa phem ntawm ib puag ncig zuj zus. Cov tshuaj kho dej yog cov pab cuam uas tsim nyog rau cov khoom siv kho dej phwj.Cov tshuaj no txawv ntawm cov teebmeem thiab siv txoj hauv kev. Ntawm no peb qhia txog kev siv cov txheej txheem ntawm cov tshuaj kho dej sib txawv.

I.Polyacrylamide siv txoj kev: (Rau kev lag luam, textile, dej phwj hauv nroog thiab lwm yam)

1.dilute cov khoom raws li 0.1% -0,3% tov. Nws yog qhov zoo dua los siv dej nruab nrab yam tsis muaj ntsev thaum diluting.(xws li dej kais dej)

2. Thov nco ntsoov: Thaum diluting cov khoom, thov tswj tus nqi ntws ntawm Tsis siv neeg dosing tshuab, kom tsis txhob agglomeration, ntses-qhov muag qhov teeb meem thiab blockage nyob rau hauv pipelines.

3.Stirring yuav tsum dhau 60 feeb nrog 200-400 rolls / min.Nws yog qhov zoo dua los tswj cov dej kub li 20-30 ℃, uas yuav ua kom nrawm nrawm dua.Tab sis thov kom kub qis dua 60 ℃.

4.Vim qhov dav ph ntau yam uas cov khoom no tuaj yeem hloov kho, qhov ntau npaum li cas tuaj yeem yog 0.1-10 ppm, nws tuaj yeem hloov kho raws li cov dej zoo.

Yuav siv cov xim coagulant li cas: (Cov tshuaj tshwj xeeb yog siv los kho cov dej phwj tuaj)

1. Hauv kev ua haujlwm pleev xim, feem ntau ntxiv cov xim pos huab coagulant A thaum sawv ntxov, thiab tom qab ntawd tshuaj tsuag xim ib txwm. Thaum kawg, ntxiv cov xim pos huab coagulant B ib nrab teev ua ntej tawm haujlwm.

2. Lub dosing point ntawm cov xim pos huab coagulant A tus neeg saib xyuas yog nyob rau hauv lub inlet ntawm circulating dej, thiab dosing point ntawm tus neeg sawv cev B yog nyob rau hauv lub qhov hluav taws xob ntawm circulating dej.

3. Raws li tus nqi ntawm cov xim pleev xim thiab cov nyiaj ntawm cov dej ntws, kho cov xim pleev xim coagulant A thiab B raws sij hawm.

4. Ntsuas tus nqi PH ntawm cov dej ntws tsis tu ncua ob zaug hauv ib hnub kom nws nyob nruab nrab ntawm 7.5-8.5, kom tus neeg sawv cev no tuaj yeem muaj txiaj ntsig zoo.

5. Thaum cov dej ntws mus rau ib lub sij hawm, qhov conductivity, SS tus nqi thiab tshem tawm cov ntsiab lus ntawm cov dej circulating yuav dhau ib tug nqi, uas yuav ua rau tus neeg sawv cev no nyuaj rau yaj nyob rau hauv lub circulating dej thiab yog li ntawd cuam tshuam cov nyhuv. ntawm tus neeg sawv cev no. Nws raug nquahu kom ntxuav lub tank dej thiab hloov cov dej ntws ua ntej siv. Lub sij hawm hloov dej muaj feem xyuam rau hom xim, qhov ntau npaum li cas ntawm cov xim, kev nyab xeeb thiab cov xwm txheej tshwj xeeb ntawm cov khoom siv txheej txheej, thiab nws yuav tsum tau ua raws li cov lus pom zoo ntawm cov kws tshaj lij ntawm qhov chaw.
