Abstract

The invention discloses a grapevine adsorption granule for heavy metals. The grapevine adsorption granule is characterized by being prepared from the following raw materials by weight: 40 to 50 parts of grapevine, 5 to 10 parts of wollastonite powder, 3 to 5 parts of light calcium carbonate, 0.1 to 0.2 part of sodium benzoate, 0.1 to 0.2 part of isopropyl myristate, 0.1 to 0.2 part of sodium methyl cocoyl taurate, 0.1 to 0.2 part of sulfamic acid, 3 to 5 parts of hydroxypropyl methyl cellulose, 0.3 to 0.5 part of dimethicone and 5 to 10 parts of a bonding auxiliary material. The adsorption granule provided by the invention has great adsorption capacity, can effectively adsorb and remove heavy metal ions in a water body, exerts certain adsorption and removal effect nitrogen and phosphorus organic matters in the water body, has strong water body purifying capability, uses widely and easily available natural matrix materials, shows good economic performance and does not produce secondary pollution to the environment.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to a vine heavy metal adsorption granule and a preparation method thereof. Background technique [0002] Due to the rapid development of industry, heavy metal pollution is becoming more and more serious. Among them, industries such as electronics, electroplating, tanning, and mineral processing produce a large amount of industrial wastewater containing heavy metal ions every year. The subsequent treatment of heavy metal wastewater has always been the focus of attention and research. . Heavy metals cannot be biodegraded in the environment, tend to be enriched in living organisms, can accumulate in the human body through the biological chain, destroy normal physiological metabolic activities, and even cause "three causes" (carcinogenic, teratogenic, and mutagenic) Substances are extremely harmful, so economical and effective methods are needed to remove various heavy metal ions in wate...
