Abstract

The present invention relates to a water treatment agent and a preparation method thereof, wherein the water treatment agent comprises, by weight, 20-30 parts of diatomaceous earth, 15-18 parts of nanoparticles with biological enzyme immobilized on the surface, 3-5 parts of graphene, 30-45 parts of perlite, 30-45 parts of vermiculite, and 10-15 parts of glycosaminoglycan. The preparation method comprises: preparing nanoparticles with biological enzyme immobilized on the surface, and then preparing the water treatment agent. According to the present invention, the water treatment agent has characteristics of good treatment effect, no pathogenicity, safety, biodegradability, environmental protection, wide raw material source, and low production cost, can be used in the fields of papermaking wastewater, heavy metal wastewater, urban sewage, food processing and fermentation industries, and the like, and has wide applicability.

Description

technical field [0001] The invention belongs to the field of environmental protection and treatment, and in particular relates to a stable, efficient, harmless and environment-friendly water treatment agent and a preparation method thereof. Background technique [0002] With the improvement of people's living standards in our country and the rapid acceleration of the urbanization process, the growth rate of various wastewater such as industrial wastewater and domestic sewage is astonishing, and the amount is huge. According to incomplete statistics, my country produces hundreds of millions of tons of industrial wastewater with high heavy metal content every year. The organic pollutants and heavy metals in these industrial wastewater are often highly toxic, which makes the water environment in the area seriously polluted, causing damage and pollution. threaten. [0003] Although domestic sewage has a small content of heavy metals, when it is discharged into rivers and lakes, ...
