1. Basic properties and mechanism of action of polyacrylamide

Polyacrylamide is an ionic organic polymer compound with good water solubility and adsorption, which can form gel and network structure. During the coagulation process, polyacrylamide aggregates and precipitates particles by interacting with particles or organic matter in the water. Specific mechanisms include charge neutralization, adsorption, bridging and gel formation.

The mechanism of action of polyacrylamide is also related to its molecular weight and charge properties. Polyacrylamide with higher molecular weight is mostly used in sewage treatment, and small particles are aggregated into large particles through bridging, which is convenient for sedimentation and removal. The charge property affects its adsorption capacity with particles in water, and polyacrylamide particles with the same charge are easy to adsorb and precipitate.

2. Application of polyacrylamide in water treatment

Polyacrylamide has a wide range of applications in water treatment, such as turbidity removal, precipitation of suspended matter, separation of colloids and dissolved organic matter, etc. During the turbidity removal process, polyacrylamide forms aggregates by bridging with suspended particles in water, which promotes the precipitation of particles. At the same time, polyacrylamide can also reduce the concentration of dissolved organic matter and improve the transparency of water by forming complexes with dissolved organic matter.

In addition, polyacrylamide can also be used to treat high-salinity water by reducing the interaction between ions in water, reducing the charge of soluble salt particles, and promoting the aggregation and precipitation of particles.

3. Coagulation mechanism and application prospects of polyacrylamide

The study of the coagulation mechanism of polyacrylamide not only helps to optimize the use method and coagulation effect of polyacrylamide, but also helps to improve the efficiency and effect of water treatment and sewage treatment. Future research can be carried out from the aspects of polyacrylamide synthesis method, molecular structure optimization, coagulation mechanism simulation, etc.

Polyacrylamide plays an indispensable role in the water treatment industry with its superior physical and chemical properties. Its wide application in industrial wastewater, municipal sewage treatment and water purification not only improves water quality and protects the ecological environment, but also makes important contributions to the realization of sustainable development. In the future, with the advancement of science and technology, the application field of PAM will continue to expand and become an important driving force for the water treatment industry.
