Environment-friendly material for treating wastewater containing cadmium compounds

Abstract

The invention discloses an environment-friendly material for treating wastewater containing cadmium compounds. The environment-friendly material is characterized by comprising the following substances in parts by weight: 20-35 parts of acrylic macromolecular water-absorbing resin, 9-16 parts of ammonia water, 3-9 parts of polypropylene fiber, 4-8 parts of aramid fiber, 2-8 parts of hollow glass bead, 1-7 parts of graphite powder, 3-6 parts of anatase titanium dioxide, 1-3 parts of lithopone, 1-8 parts of organosilicon modified epoxy resin, 0.5-1 part of nanoscale particulate inorganic material, 4-8 parts of calcium carbonate and 2-9 parts of soda lime. The environment-friendly material has the beneficial effects that the adsorption performance is good, the production cost is low, the process flow is simple, and the large-scale production is facilitated.

Description

technical field [0001] The invention relates to an environment-friendly material for treating waste water containing cadmium compounds. Background technique [0002] In many industrial processes, such as electroplating, tanning, mining, steelmaking, and dyeing, a large amount of wastewater containing cadmium heavy metal ions will be generated, and the release into the environment will endanger human health and the ecological 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, domestic and foreign treatment methods generally include activated carbon adsorption method, biodegradation method, modified bentonite adsorption method and photocatalyst degradation met...
