It is an organic-inorganic macromolecular synthetic polymer that can quickly and effectively destroy the electric double layer at the oil-water interface and reduce the strength of the interfacial film. The interaction with the anionic polymer in the wastewater is greatly reduced, and it has excellent water efficiency. At the same time, the reaction speed is very fast, the resulting compact silk flower has good fluidity, and the separation speed is fast, which can effectively avoid the sticky "containing sludge" problem in sewage treatment.
