Yuav Siv Cov Tshuaj Kho Dej Li Cas 2

Yuav Siv Cov Tshuaj Kho Dej Li Cas 3

Tam sim no peb them sai sai rau kev kho cov dej khib nyiab thaum muaj kev ua qias tuaj ntawm ib puag ncig. Cov tshuaj kho dej yog cov khoom pabcuam uas tsim nyog rau cov khoom siv kho dej phwj tuaj. Cov tshuaj no muaj cov txiaj ntsig sib txawv thiab siv cov txheej txheem. Ntawm no peb qhia txog kev siv cov tshuaj kho dej sib txawv.

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

1. dilute cov khoom raws li 0.1% -0,3% kua. Nws zoo dua siv dej nruab nrab tsis muaj ntsev thaum diluting. (Xws li dej kais)

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

3. Kev nplawm yuav tsum tshaj 60 feeb nrog 200-400 yob / feeb. Nws zoo dua los tswj cov dej kub li 20-30℃, qhov ntawd yuav ua kom cov yaj sai dua. Tab sis thov xyuas kom qhov kub qis dua 60℃.

4. Vim yog qhov ntau ntawm 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 qhov zoo ntawm dej.

Yuav siv polyaluminum chloride li cas: (siv rau kev lag luam, luam ntawv thiab dyeing, cov dej khib nyiab hauv nroog, thiab lwm yam)

　　1. Yaj cov khoom polyaluminum chloride nrog dej ntawm qhov sib piv ntawm 1:10, do nws thiab siv.

　　2. Raws li qhov sib txawv ntawm cov dej nyoos turbidity, qhov koob tshuaj zoo tshaj plaws tuaj yeem txiav txim siab. Feem ntau, thaum cov dej nyoos turbidity yog 100-500mg / L, qhov koob tshuaj yog 10-20kg ib txhiab tons.

　　3. Thaum cov dej nyoos turbidity siab, cov tshuaj ntxiv tuaj yeem nce ntxiv kom haum; thaum cov turbidity tsawg, cov tshuaj ntxiv tuaj yeem txo kom haum.

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