Nrog rau txoj kev loj hlob sai ntawm cov neeg ua haujlwm kho dej, cov khoom lag luam tau dhau los ua haujlwm zoo thiab ib puag ncig zoo, thiab nws qhov dav thiab kev ua tau zoo tsis yog xam los ntawm peb, feem ntau vim tias nws muab rau peb lub neej tau coj ntau yam kev pab, ntawm no yog cov kev taw qhia ntawm nws peb txoj kev kho mob muaj zog.
Cationic polyacrylamide
Tus neeg saib xyuas dej tsis sib haum nrog feem ntau cov kuab tshuaj organic, muaj cov nyhuv flocculation zoo, thiab tuaj yeem txo cov kev sib txhuam ntawm cov kev daws teeb meem zoo. Nws yog tsuas yog siv nyob rau hauv sludge dewatering thiab industrial wastewater kho. Yuav tsum xyuam xim rau daim ntawv thov:
(1) Siv cov dej nruab nrab tsis muaj ntsev rau kev teeb tsa khoom.
(2) Thaum dissolving, nws yog tsim nyog rau uniformly kis tus neeg sawv cev rau hauv lub stirring dej.
(3) Tus neeg sawv cev yog hygroscopic thiab yuav tsum tau muab cia rau hauv qhov chaw qhuav qhuav.
2.CF1 polyaluminium chloride
Tus neeg sawv cev kho dej yog polymerized los ntawm ib qho inorganic polymer coagulant thiab ib tug natural polymer flocculant, yog li ntawd nws exerts nws tus yam ntxwv zoo thiab muaj ib tug zoo ntxim rau cov kev kho mob ntawm cov organic contaminated raw cov ntaub ntawv, thiab yuav tau yoog mus rau ntau yam ntaub ntawv ntawm sedimentation tso tsheb hlau luam. Daim ntawv thov:
(1) Cov kua ntawm cov tshuaj tuaj yeem raug ntxiv ncaj qha, lossis tuaj yeem ntxiv tom qab dilution, thiab cov khoom yuav tsum tau yaj thiab siv.
(2) Qhov ntau npaum ntawm cov tshuaj yuav tsum tau ntsuas raws li tus nqi ntawm cov dej kho.
(3) Tsis txhob sib xyaw nrog lwm cov tshuaj thaum siv.
3. Anionic polyacrylamide
Tus neeg sawv cev tsuas yog siv hauv kev kho dej khib nyiab thiab roj av, geological drilling additives. Kev ceev faj rau kev siv yog zoo ib yam li cov cationic polyacrylamide. Tsis tas li ntawd, kev saib xyuas yuav tsum tau saib xyuas kom tsis txhob kis cov tshuaj hauv av kom tsis txhob muaj kev hloov pauv hauv av tom qab nqus dej noo.
