Treatment of Chemical Industrial Wastewater -- Nonionic Polyacrylamide

Ⅰ. Nonionic flocculant for industrial wastewater treatment

Nonionic polyacrylamide is a water-soluble high-molecular polymer. Its molecular chain contains polar groups, which can adsorb particles suspended in the solution, so that the particles agglomerate to form larger flocs. The formed larger flocs can accelerate the precipitation of suspended particles and accelerate the effect of solution clarification. Compared with ordinary wastewater treatment, chemical industry wastewater is very complicated. Various agents such as flocculants, coagulants and decolorizers are needed in the process of treating chemical industry wastewater. Among them, the frequently used flocculant is nonionic polyacrylamide.

Ⅱ. The trend of nonionic polyacrylamide

1. The molecular chain of nonionic polyacrylamide contains polar groups, which can absorb particles suspended in water and bridge between particles to form larger flocs.

2. Nonionic polyacrylamide can accelerate the precipitation of suspended particles by forming larger flocs, thereby speeding up the clarification of the solution and promoting the effect of filtration.

3. Among all the flocculant products, nonionic polyacrylamide has the best effect in treating acidic wastewater, and chemical industrial wastewater is generally acidic. Therefore, nonionic polyacrylamide has its specific advantages in the treatment of chemical industry wastewater.

4. The coagulant can be used with inorganic salts such as inorganic flocculants polyaluminum, polyiron, etc., and the effect will be better. It is precisely because nonionic polyacrylamide has such characteristics that it has obvious advantages in the treatment of chemical industrial wastewater.
