Polyacrylamide is a kind of polymer compound which is commonly used as flocculant and precipitant in industrial wastewater treatment. Industrial sewage contains a lot of suspended solids and dissolved organic matter, which will cause serious pollution and ecological damage to the water environment. Therefore, effective treatment of industrial sewage is essential to protect the water environment and ecosystem.

The main function of polyacrylamide in industrial wastewater treatment is to aggregate suspended solids and organic matters into large particles, so that it is easy to precipitate and separate. Polyacrylamide molecule contains a large number of amino and carbonyl functional groups, these functional groups can form compounds with various ions and molecules in industrial sewage, thus increasing the size and density of suspended solids and organic matters.

When using polyacrylamide to treat industrial sewage, it is usually necessary to add it to the sewage and make it fully mixed by means of mechanical mixing, etc. Polyacrylamide forms compounds with suspended solids and organic matters in sewage, which gradually aggregate into large particles and settle to the bottom of the sewage. During the precipitation process, some auxiliary chemicals such as coagulant or defoamer can also be added to improve the precipitation efficiency and cleanliness.

It should be noted that when using polyacrylamide to treat industrial sewage, the appropriate type and dosage of polyacrylamide should be selected according to the actual situation to ensure the best treatment effect. At the same time, the treated sewage should also be carefully tested and monitored to ensure that the treated water quality meets the relevant standards and requirement.

In short, as a kind of efficient industrial sewage treatment chemical, polyacrylamide can effectively remove suspended solids and organic matters in sewage, purify the water environment, protect the ecosystem. However, it is necessary to select the appropriate type and dosage when using, and monitor the water quality after treatment to ensure the treatment effect and water safety.
