Composite material adsorbing cadmium-compound-containing wastewater

Abstract

A disclosed composite material adsorbing cadmium-compound-containing wastewater is characterized by comprising the following substances in parts by weight: 20-35 parts of acrylic high-molecular water-absorption resin, 9-16 parts of ammonia water, 7-16 parts of gallic acid, 1-2 parts of nanometer calcium sulfate, 2-7 parts of a titanate coupling agent, 0.1-0.3 parts of nanometer silver, 1-2 parts of maleic anhydride grafted polypropylene, 2-3 parts of polyethylene glycol terephthalate, 10-16 parts of an aqueous solution of cement mortar, and 2-9 parts of alkali lime. The beneficial effects comprise that the composite material is good in adsorption performance, low in production cost, simple in technological process and beneficial for large-scale production.

Description

technical field [0001] The invention relates to a composite material for adsorbing cadmium-containing compound waste water. Background technique [0002] In many industrial processes, such as electroplating, tanning, mining, steelmaking, and dyeing temples, a large amount of wastewater containing cadmium heavy metal ions will be produced, which will endanger human health and the ecological environment when released into the environment. Therefore, the treatment of cadmium-containing heavy metal ion wastewater has always been the focus and difficulty of people's attention and research. In recent years, the development of innovative technologies to reduce the content of cadmium heavy metal ions in aqueous solutions to a safe range has attracted widespread attention and attention. At present, the treatment methods at home and abroad generally include activated carbon adsorption method, biodegradation method, modified bentonite adsorption method and photocatalyst degradation me...
