摘要:
With the rapid development of China's economy, the components of sewage discharged from industrial manufacturing and daily life have gradually become diversified, resulting in a large amount of sludge generated during the sewage treatment process. Sludge contains a large amount of phosphorus, nitrogen, potassium and metal elements. For sludge dewatering, organic polymer flocculants have demonstrated more outstanding dewatering performance compared with previous inorganic flocculants. Therefore, this paper mainly analyzes and studies the application of organic polymer flocculants in sludge dewatering, objectively expounds the application effects of different types of organic polymer flocculants in sludge dewatering in recent years, and how to select organic polymer flocculants. By summarizing their treatment methods, it can be concluded that the addition of cationic inorganic flocculants and the proportioning of organic polymer flocculants with a relatively high molecular content have more outstanding performance in the actual application of sludge dewatering.
