Lub invention belongs rau lub technical teb ntawm cov xim pos huab flocculant ntau lawm, thiab tshwj xeeb tshaj yog muaj feem xyuam rau ib tug xim pos huab flocculant, ib txoj kev npaj thiab daim ntawv thov ntawm no. Cov xim pos huab flocculating tus neeg sawv cev uas twb muaj lawm muaj cov nyhuv flocculation tsis zoo, COD tshem tawm, tiv thaiv corrosion thiab tiv thaiv xeb, yog li cov khoom tsim tau muab cov xim pos huab flocculating tus neeg sawv cev, uas suav nrog cov ntaub ntawv raw ntawm A tus neeg saib xyuas thiab B tus neeg sawv cev; Tus neeg sawv cev muaj xws li, los ntawm qhov hnyav, 1-5 qhov chaw ntawm cov amino compound, 1-5 qhov chaw ntawm aldehyde compound, 30-60 qhov chaw ntawm bentonite thiab 10-20 qhov chaw ntawm polyaluminium chloride; tus neeg sawv cev B muaj 0.5-1.5 feem ntawm polyacrylamide, 0.3-1 feem ntawm cov kab mob, 20-40 qhov chaw ntawm antirust additive thiab 2-6 qhov chaw ntawm defoamer; Tus neeg sawv cev A thiab tus neeg sawv cev B ob leeg suav nrog 300 feem ntawm dej. Lub invention kuj muab ib txoj kev npaj thiab siv cov xim pos huab flocculating tus neeg sawv cev. Cov flocculant yog siv rau cov xim pos huab tshem tawm tus nqi nyob rau hauv cov dej khib nyiab, uas yog ntau tshaj 95%, tuaj yeem txo SS cov khoom raug tshem tawm, ib txhij txo COD ntau dua 55%, thiab tuaj yeem siv dav rau kev kho cov xim hauv cov dej khib nyiab.
