Yuav ua li cas siv cov tshuaj tua dej 3

Tam sim no peb them ntau dua rau kev kho cov dej khib nyiab thaum ib puag ncig kev kho mob yog qhov tsim nyog. Ntawm no peb qhia txog cov kev siv rau ntawm cov dej tshuaj txawv txawv.

I.PolyaCryaGrylamide siv cov qauv: (rau kev lag luam, textile, dej phwj tuaj thiab lwm yam)

1.Dilute cov khoom raws li 0.1% -0,3% kev daws teeb meem. Nws yuav zoo dua los siv cov dej nruab nrab tsis muaj ntsev thaum diluting. (Xws li kais dej)

2. Thov kom yuam: Thaum diluting cov khoom, thov tswj hwm tus nqi ntws ntawm tsis siv neeg siv lub tshuab tsis siv neeg, kom tsis txhob agglomeration, ntses qhov xwm txheej thiab cov kev txwv hauv lub xov tooj.

3.Stirring yuav tsum tau tshaj 60 feeb nrog 200-400 yob / min.it zoo dua los tswj cov dej kub li 20-30℃, uas yuav ua kom nrawm dua qhov kev sib cais.but thov ua kom paub tseeb qhov kub qis dua 60℃.

4.Due rau cov lus dav dav tias cov khoom lag luam no tuaj yeem hloov kho, cov tshuaj yuav ua tau 0.1-10 ppm, nws tuaj yeem hloov kho raws li cov dej zoo.

Yuav siv polyaluminum chloride li cas: (Siv rau kev lag luam, luam ntawv thiab daub thiab dej hauv nroog, thiab lwm yam)

　　1. Daws cov khoom siv polyaluminum chloride cov khoom siv nrog dej ntawm ib feem ntawm 1:10, do nws thiab siv.

　　2. Raws li qhov sib txawv ntawm cov dej nyoos, cov kev ua tau zoo nkauj tau txiav txim siab. Feem ntau, thaum lub tshuab luam yeeb ntawm cov dej nyoos yog 100-500mg / l, cov tshuaj yog 10-20k ib txhiab tons.

　　3. Thaum lub turbidity ntawm cov dej nyoos yog siab, cov tshuaj noj tau tuaj yeem tsim kev nce ntxiv; Thaum lub qhov turbidity yog tsawg, qhov ntau npaum li cas tuaj yeem raug txo qis.

　　4. Polyaluminium chloride thiab polyacrylamide (anionic, cationic, tsis yog-ionic) tau siv ua ke rau cov txiaj ntsig zoo dua.
