Abstract

The invention discloses a foamed nickel and iron carbon combined biological filler and a preparation method thereof. The foamed nickel and iron carbon combined biological filler includes foamed nickel, and iron carbon particles are wrapped in the foamed nickel; the foamed nickel has an ultrathin knitmesh flaky structure; an iron carbon particle matrix is cylindrical particles, and the outer surface of the matrix is covered with iron spicules fully. The preparation method of the foamed nickel and iron carbon combined biological filler comprises that the iron carbon particles are completely wrapped in the flaky foamed nickel, the product has a shape of sphere, and the foamed nickel is supported on the surface of the iron carbon particles by an iron needle-shaped net. The foamed nickel is prepared by an electrodeposition technology. The foamed nickel is a polyester polyurethane foamed plastic having pores opened by mechanical blasting, and the foamed plastic is composed of dodecahedral structural units with pentagonal windows. By adopting of the foamed nickel and iron carbon combined biological filler and the preparation method thereof, the energy consumption of the waste water and waste gas purification systems can be greatly reduced, the process treatment process does not involve secondary pollution, and the purification efficiency of degradation-resistant organic pollutants canbe fully improved.

Description

technical field [0001] The invention belongs to the technical field of electrochemical treatment of organic waste water and organic waste gas, and in particular relates to a combined biological filler of nickel foam and iron-carbon and a preparation method thereof. Background technique [0002] Water and atmosphere are the important basis for human life and production, and are indispensable resources for human beings. However, since the 20th century, with the rapid development of industry, more and more untreated or partially treated industrial waste liquids have infiltrated into the ground, injected into rivers or lakes and other surface water bodies, and the types and quantities of waste water have increased rapidly, seriously It affects the water quality of aquifers and surface water bodies, aggravating the crisis of water resources, and the quality of water bodies in the world is generally threatened. Due to the complex composition of industrial wastewater, organic wast...
