Recently, with the improvement of environmental protection requirements and the upgrading of industrial technology, polyacrylamide (referred to as PAM), as a multi-functional high molecular polymer, has shown increasingly prominent application value in fields such as water treatment, oil exploitation, and papermaking industry. It has become a key material for promoting the green transformation and efficiency improvement of relevant industries.

In the field of water treatment, PAM has become a "main force" in sewage purification by virtue of its excellent flocculation performance. Whether in the sludge dewatering link of municipal sewage treatment or the clarification treatment of industrial wastewater (such as printing and dyeing wastewater and chemical wastewater), adding an appropriate amount of PAM can quickly adsorb suspended particles in water, form larger flocs to accelerate precipitation, and significantly reduce water turbidity and pollutant content. The person in charge of a sewage treatment plant said that after using PAM, the sewage purification efficiency has increased by more than 30%, and the water content of sludge has been significantly reduced, which not only reduces the treatment cost but also provides a guarantee for the recycling of water resources.

The oil exploitation industry is also inseparable from the support of PAM. In the later stage of oilfield exploitation, by injecting PAM solution into oil wells, the oil-water mobility ratio can be effectively improved, and the crude oil recovery rate can be increased. Especially in the tertiary oil recovery technology, the thickening and oil-displacing properties of PAM help oilfields break through the exploitation bottleneck. With the help of this technology, some old oilfields have increased their recovery rate by 5%-10%, providing technical support for the efficient development of energy.

In addition, PAM also plays an important role in the papermaking industry. As a paper strength agent and retention aid, PAM can enhance the binding force between paper fibers, reduce paper breakage, and at the same time improve the retention rate of fibers and fillers in pulp, thereby reducing raw material loss and wastewater discharge. The relevant person in charge of a papermaking enterprise introduced that after introducing PAM, the yield rate of finished paper has increased by nearly 8%, and the pressure of papermaking wastewater treatment has been significantly reduced, which is in line with the development trend of green production in the current industry.

Insiders pointed out that with the continuous innovation of technology, the application scenarios of PAM are still expanding. In the future, more breakthroughs are expected in fields such as agricultural water-saving irrigation and mine solid waste treatment, injecting new momentum into the high-quality development of various industries.
