Description

technical field [0001] The invention belongs to the field of water treatment materials, and in particular relates to an environment-friendly water treatment flocculation material and a preparation method thereof. Background technique [0002] Water treatment can effectively remove the turbidity in the water to be treated and reduce the pollution load of the subsequent treatment of sewage. [0003] Commonly used water treatment flocculation materials can be divided into inorganic flocculants and organic flocculants according to their chemical composition. Among them, organic flocculants include organic coagulants and organic polymer flocculants; organic flocculants include synthetic organic polymer flocculants, natural organic polymer flocculants and microbial flocculants. Commonly used polymer flocculants include basic polyaluminum chloride, polyaluminum sulfate, and polyferric sulfate. Although the low-molecular-weight flocculant has overcome the problem of low processing ...
