Yuav Siv Cov Tshuaj Kho Dej Li Cas 2

Yuav Siv Cov Tshuaj Kho Dej Li Cas 3

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 tshaj 60 feeb nrog 200-400 yob / min.Nws yog qhov zoo dua los tswj cov dej kub li 20-30℃, uas yuav ua rau kom lub dissolution.Tab sis thov kom paub tseeb tias qhov kub thiab txias yog 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 li cas polyaluminium chloride: (muaj feem xyuam rau kev lag luam, luam ntawv thiab dyeing, dej khib nyiab hauv nroog, thiab lwm yam)

　　1. Dissolve cov khoom polyaluminium chloride khoom nrog dej ntawm qhov sib piv ntawm 1:10, do thiab siv.

　　2. Raws li qhov sib txawv turbidity ntawm cov dej nyoos, qhov kev pom zoo tuaj yeem txiav txim siab. Feem ntau, thaum lub turbidity ntawm cov dej nyoos yog 100-500mg / L, qhov ntau npaum li cas yog 10-20kg ib txhiab tons.

　　3. Thaum lub turbidity ntawm cov dej nyoos yog siab, qhov ntau npaum yuav tsum tau nce; Thaum cov turbidity tsawg, qhov ntau npaum yuav raug txo kom tsim nyog.

　　4. Polyaluminium chloride thiab polyacrylamide (anionic, cationic, non-ionic) yog siv ua ke kom tau txais txiaj ntsig zoo dua.
