Preparation method of flocculant containing potassium monopersulfate composite salt as well as product and application of flocculant

Abstract

The invention provides a preparation method of a flocculant containing potassium monopersulfate composite salt as well as a product and an application of the flocculant. The potassium monopersulfate composite salt is prepared by hydrolyzing potassium persulfate, is mild in property, has neutral pH after being dissolved in water, and has good sterilization and water body improvement effects. Afterbeing compounded with a traditional flocculant, the flocculant contains a special biomass flocculant, is mainly used for chelating heavy metal ions and activated sludge, has unique biological activity, biodegradability, biocompatibility, good adhesiveness, relatively strong fiber-forming and film-forming capabilities, special adsorption performance and the like, and has important application in the aspect of water treatment.

Description

technical field [0001] The invention relates to a preparation method of a flocculant, in particular to a preparation method containing potassium monopersulfate compound salt and its product and application. Background technique [0002] According to its chemical composition, flocculants can be generally divided into two types: inorganic flocculants and organic flocculants. Inorganic flocculants include inorganic coagulants and inorganic polymer flocculants; organic flocculants include synthetic organic polymer flocculants, natural organic polymer flocculants and microbial flocculants. The flocculant is mainly a group with positive (negative) charge and some particles or particles with negative (positive) charge in water that are difficult to separate, close to each other, reduce its potential, make it in an unstable state, and use its The aggregated nature allows these particles to be concentrated and separated by physical or chemical means. [0003] Flocculants are mainly...

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 type of polymer have "three-caused" effects (teratogenic, carcinogenic, mutagenic), thus limiting its application range

[0004] Affected by human activities, elements such as nitrogen and phosphorus are continuously discharged into the water body, making the water body eutrophic. The algae plants and plankton in the water continue to multiply, destroying the food chain and breaking the ecological balance. Cyanobacteria are ancient creatures in the dinosaur era. Under appropriate temperature and nutrient conditions, large-scale reproduction will seize the growth space of water organisms, consume dissolved oxygen in water, and release algae toxins, which will also endanger human health and increase water treatment costs.
