Types and functions of wastewater treatment chemicals in paper mills. Paper mill wastewater without treatment will cause serious pollution to the environment. Polyacrylamide and polyaluminum chloride are commonly used to treat papermaking wastewater. Today, the editor of Haonuo will focus on explaining how polyacrylamide chemicals treat wastewater from paper mills. Cationic polyacrylamide is routinely used in papermaking wastewater treatment. Non-ions are usually used to treat pulp retention and drainage in the papermaking process.
> Papermaking wastewater mainly comes from the two production processes of pulping and papermaking in the papermaking industry. Pulping and papermaking both discharge large amounts of wastewater. The wastewater produced by pulping is the most polluted. The wastewater discharged during pulp washing is dark brown and is called black water. The concentration of pollutants in black water is very high and contains a large amount of fiber, inorganic salts and pigments. Cationic polyacrylamide is needed to remove sewage in papermaking. In the pulping and papermaking processes, it is used as a retention agent, filter aid, leveling agent, etc. Reinforcing agents and other additives for papermaking. Improve the retention rate of fillers, pigments, etc. and the strength of paper.
