Description

technical field

[0001] The invention relates to the technical field of wastewater treatment, in particular to a crown ether-based flocculant for papermaking wastewater treatment and a preparation method thereof. Background technique

[0002] In recent years, with the advancement of global industrialization, environmental problems have become increasingly serious and have become a mountain restricting social and economic development. Water pollution is one of many environmental problems. It directly threatens people's health, and at the same time, it will lead to the waste of water, the source of life, and cause a shortage of water resources. Therefore, the development of wastewater treatment technology is imperative.

[0003] Papermaking wastewater is a representative type of wastewater. Because it contains a lot of fibers, pigments and inorganic salts, it will turn the water black and have a special foul smell. These pollutants are difficult to deal with, which hinders th...
