Environment-friendly treating agent for wastewater containing zinc and nickel and preparation method of treating agent

Abstract

The invention discloses an environment-friendly treating agent for wastewater containing zinc and nickel and a preparation method of the treating agent. The treating agent for the wastewater comprises 4-10 parts of polyethylenimine, 3-8 parts of calcium silicate, 2-5 parts of barium chloride, 5-10 parts of hectorite, 3-7 parts of sodium polyacrylate, 4-12 parts of hydroxysodalite and 3-6 parts of sodium lignin sulfonate. The preparation method comprises following steps: (1), calcium silicate, barium chloride and hydroxysodalite are ground by a grinder; (2), 4-10 parts of polyethylenimine, 3-8 parts of calcium silicate, 2-5 parts of barium chloride, 5-10 parts of hectorite, 3-7 parts of sodium polyacrylate, 4-12 parts of hydroxysodalite and 3-6 parts of sodium lignin sulfonate are weighed and stirred uniformly, and the environment-friendly treating agent for the wastewater containing zinc and nickel is obtained. The zinc and nickel reducing rate of the prepared environment-friendly treating agent for the wastewater is higher than 75%.

Description

technical field [0001] The invention belongs to the field of environment-friendly materials, and in particular relates to an environment-friendly treatment agent for wastewater containing zinc and nickel and a preparation method thereof. Background technique [0002] Zinc is a heavy metal resource that is abundant in the earth. my country's zinc reserves rank second in the world, and zinc resources are widely used in modern industrial production such as smelting, pharmaceutical and food industries. Zinc is an indispensable element for human health. It widely exists in human muscles and bones, but the content is very small. If it is excessive, serious consequences will occur. The discharge of zinc-containing wastewater is a serious hazard to human health and industrial and agricultural activities. It is persistent, highly toxic, and seriously polluting. Once it enters the environment, it cannot be biodegraded. Most of it participates in the food chain cycle and eventually ac...

The discharge of zinc-containing wastewater is a serious hazard to human health and industrial and agricultural activities. It is persistent, highly toxic, and seriously polluting. Once it enters the environment, it cannot be biodegraded. Most of it participates in the food chain cycle and eventually accumulates in organisms. Destroy the normal physiological and metabolic activities of organisms and endanger human health
