Problems solved by technology

Inorganic flocculants can be divided into low-molecular flocculants and high-molecular flocculants. Low-molecular flocculants include aluminum salts and iron salts. The cost of low-molecular flocculants is low, but their flocculation and precipitation speed is slow and the consumption of flocculants is high. ; Commonly used polymer flocculants include basic polyaluminum chloride, polyaluminum sulfate, and polyferric sulfate. Poor processing effect

The nano flocculation material for water treatment comprises components in parts by weight as follows: 45-55 parts of dimethylamino ethyl methacrylate, 8-12 parts of diallyl dimethyl ammonium chloride, 8-11 parts of mannitol, 7-9 parts of N-(5-ethoxy) nicotinamide nitrate, 3-5 parts of hydroxypropyl methyl cellulose, 2-3 parts of polyoxyethylene sorbitan monooleate, 3-5 parts of cetyl alcohol, 1-1.5 parts of activated carbon fiber and 0.5-1 part of borax. The invention further provides a preparation method of the nano flocculation material for water treatment.

Description

technical field [0001] The invention belongs to the field of water treatment materials, in particular to a nanometer 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. Commonly used water treatment reagents include flocculants, which 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. Inorganic flocculants can be divided into low-molecular flocculants and high-molecular flocculants. Low-molecular flocculants include aluminum salts and iron salts. The cost of low-molecular flocculants is low, but their floc...
