Abstract

The invention discloses a coating debonding wastewater flocculant with a peculiar smell removal function and a preparation method thereof. The flocculant comprises cationic polyacrylamide, alkyl dimethyl ammonium chloride, an inorganic flocculant, a plant extract, sodium percarbonate, activated carbon, an emulsifier, ammonium persulfate and water. The cationic polyacrylamide and the alkyl dimethyl ammonium chloride form a network structure, the inorganic flocculant is combined, the flocculation effect can be better achieved, the alkyl dimethyl ammonium chloride, the plant extract and the sodium percarbonate have the synergistic effect, the sterilization performance is excellent, growth of microorganisms in waste water can be inhibited or the microorganisms can be killed, and the pollution of pungent smell generated by reproduction and metabolism of the microorganisms is eliminated.

Description

technical field [0001] The invention relates to the technical field of flocculant processing, in particular to a coating debonding wastewater flocculant with the function of removing peculiar smell and a preparation method thereof. Background technique [0002] A large amount of organic matter and inorganic minerals are used in the production process of water-based paint, which makes the chemical oxygen demand and suspended solids of paint wastewater rise sharply. Macromolecular organic matter exists in the state of sol in wastewater, and forms a stable dispersion system with insoluble suspended particles in wastewater, which makes it difficult to separate out and settle suspended solids in wastewater, and it is difficult to destroy the stability. Therefore, the coating wastewater needs to be debonded, and the debonded wastewater is separated from the above-mentioned substances by flocculation and other means. [0003] Traditional water treatment flocculants, such as polyac...
