In addition to polymer flocculation, anionic polyacrylamide also undergoes ion adsorption, bridging, and electrical neutralization in the sedimentation of coal slurry. When the anionic degree is 30%, these effects are combined to achieve good flocculation effect. Therefore, it is advisable to control the anionic degree of polyacrylamide used for coal slurry water treatment at around 30%. The difference in flocculation effect between two different types of coal slurry water is very small, similar to the effect of non ionic polyacrylamide. Both have better flocculation effect on primary coal slurry with large particle size and low ash content than flotation tailings with fine particle size and high ash content.

Due to the complex changes in wastewater quality, the composition and charge properties vary greatly, and the treatment effect is also different. Therefore, in practical applications, it is necessary to first understand the water quality of wastewater, and then select appropriate cationic polyacrylamide flocculants based on this, to exert the charge neutralization and adsorption bridging effects of the flocculants. The effectiveness of its treatment of wastewater is related to factors such as relative molecular weight, cation degree, addition amount, and stirring time.

Cationic polyacrylamide exhibits cationic properties in both acidic and alkaline media, and its molecular weight is usually lower than that of anionic or non ionic polyacrylamide. Its performance in purifying wastewater is mainly achieved through charge neutralization. The main function of this type of flocculant is to flocculate with negative charges and has functions of turbidity removal and decolorization. In the treatment of wastewater from alcohol factories, monosodium glutamate factories, sugar factories, meat products factories, beverage factories, printing and dyeing factories, the use of cationic polyacrylamide is several times or tens of times more effective than the use of anionic polyacrylamide, non ionic polyacrylamide, or inorganic salts, because such wastewater generally carries negative charges.

Polyacrylamide is a polymer organic coagulant commonly used in sewage treatment, and in some cases, it is also used in water supply treatment. Due to the excessive dosage of inorganic coagulants and the inability to achieve the desired treatment effect, high molecular organic coagulant polyacrylamide was used to treat high turbidity water. The molecular weight of polyacrylamide can be divided into low, medium, high, and ultra-high.

The molecular weight of polyacrylamide is generally 1.5 × 106~6 × 107. When the residual polymer content is 600mg/L, the flocculation effect of cationic polyacrylamide has significant fluctuations, making it difficult to obtain accurate measurement results. Through the investigation of the flocculation effect of cationic polyacrylamide, the analysis shows that at the same temperature, with the increase of dosage, the transmittance will gradually increase, reach the applicable value, and then decrease. Moreover, due to the unique structure of C-polyacrylamide, its flocculation effect has significant fluctuations, with poor repeatability and reproducibility.

The residual polymer content has a significant impact on its flocculation effect. When the residual polymer content is very high, there is basically no flocculation effect. Only when the residual polymer content is low, it has a certain flocculation effect, but it is still not good. The anionic degree of polyacrylamide affects the flocculation effect. The transmittance of coal slurry water increases with the increase of anionic degree, reaching its peak value at an anionic degree of 30%, and then decreases with further increase of anionic degree. In addition to polymer flocculation, anionic polyacrylamide also undergoes ion adsorption, bridging, and electrical neutralization in the sedimentation of coal slurry. When the anionic degree is 30%, these effects are combined to achieve good flocculation effect. Therefore, it is advisable to control the anionic degree of polyacrylamide used for coal slurry water treatment at around 30%.
