Kev Siv Cov Tshuaj Txhim Kho Dej 2

Kev Siv Tshuaj Txhim Kho Dej Tshuaj 3

Tam sim no peb tau them nyiaj ntau dua rau kev kho cov dej khib nyiab thaum muaj kuab paug ib puag ncig zuj zus.Peb cov tshuaj kho dej yog cov pabcuam uas tsim nyog rau cov khoom siv dej phwj tuaj. Cov tshuaj no sib txawv hauv kev cuam tshuam thiab kev siv txoj hauv kev. Ntawm no peb qhia cov kev siv ntawm cov tshuaj ntxuav dej sib txawv.

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

1.dilute cov khoom ua 0.1% -0,3% kev daws. Nws yuav zoo dua yog siv cov dej nruab nrab uas tsis muaj ntsev thaum diluting. (Xws li cov kais dej)

2.Thov nco ntsoov: Thaum diluting cov khoom, thov tswj tus nqi ntws ntawm Tsis Siv Neeg Dosing Tshuab, kom tsis txhob muaj agglomeration, ntses-qhov muag teeb meem thiab txhaws hauv cov raj xa dej.

3.Qhov taws yuav tsum dhau 60 feeb nrog 200-400 rolls / min.Nws zoo dua rau kev tswj dej kub raws li 20-30 , uas yuav laij kom qhov xaus sai sai tab sis Tab sis thov paub tseeb tias qhov ntsuas kub yog qis dua 60 .

4.Due rau qhov dav ph ntau 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 tsis zoo.

 Yuav ua li cas siv polyaluminium chloride: (siv rau kev lag luam, luam ntawv thiab zas, cov dej tsis huv hauv nroog, thiab lwm yam)

   1. Dov tawm cov khoom ua tiav polyaluminium chloride khoom nrog dej ntawm qhov sib piv ntawm 1:10, do nws thiab siv.

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

  3. Thaum lub turbidity ntawm cov dej nyoos muaj siab, qhov ntau npaum li cas tuaj yeem tsim nyog ntxiv; thaum lub cav tsis muaj zog, qhov ntau npaum li qhov ua tau tuaj yeem raug txo kom tsawg.

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