Abstract

A disclosed green environment-friendly material for adsorption treatment of phosphorus-containing wastewater is characterized by comprising the following substances in parts by weight: 8-16 parts of graphite, 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 9-15 parts of ferric oxide. The green environment-friendly material is excellent in adsorption capability, wide in application scope and easily available in raw materials, and a microwave reducing method is simple, the technology is simple and suitable for large-scale production.

Description

technical field [0001] The invention relates to a green environment-friendly material for adsorbing wastewater containing phosphorus. Background technique [0002] The discharge of a large amount of domestic sewage and industrial wastewater containing phosphorus, nitrogen and other elements causes the rapid reproduction of plankton in the water body, reduces the oxygen content of the water body, and seriously pollutes the water environment, which has brought great harm to industry, agriculture, tourism, etc. harm. In today's society, people are more and more interested in environmental protection. Research and development of efficient wastewater phosphorus removal materials and technologies to remove phosphorus in different water qualities and avoid eutrophication of water bodies is one of the hot issues in controlling water pollution. At present, the treatment of phosphorus-containing wastewater mainly includes biological methods, chemical methods and adsorption methods. ...
