Problems solved by technology

Inorganic flocculants are cheap, but they will have adverse effects on human health and the ecological environment; although organic polymer flocculants are used in a small amount, the scum output is small, the flocculation ability is strong, the flocs are easy to separate, and the effect of removing oil and suspended matter is good , but the residual monomers of this kind of high polymer are easy to cause roughness, carcinogenicity and mutagenesis, so its application range is limited; microbial flocculants are easy to use because there is no secondary pollution, and their application prospects are promising

Abstract

The invention discloses a flocculating agent. The flocculating agent comprises the following components: coal ash, starch, ferrous sulphate, sodium oxide, zinc chloride, aluminum sulfate, polyacrylamide, polyvinylpyrrolidone, and polymeric phosphato-aluminum chloride. The flocculating agent has the advantages of stable chemical performance, low consumption amount, wide feeding range, short precipitation formation time, large form for facilitating precipitation, shortened retention time of water samples in a treatment system, and the like; the treatment capability of the system is improved, and pH value of treated water is not influenced.

Description

technical field [0001] The invention relates to a chemical preparation, in particular to a flocculant, and belongs to the technical field of water treatment. Background technique [0002] In the water treatment process, the flocculant mainly neutralizes the groups with positive (negative) charges and some particles with negative (positive) charges in the water that are difficult to separate, reducing their potential, making them in an unstable state, and Using its polymeric properties, these particles are concentrated and separated by physical or chemical methods. [0003] Flocculants are mainly divided into two categories: inorganic and organic, and there are also microbial flocculants. Inorganic flocculants are cheap, but they will have adverse effects on human health and the ecological environment; although organic polymer flocculants are used in a small amount, the scum output is small, the flocculation ability is strong, the flocs are easy to separate, and the effect o...
