Embodiment 1

[0050] Catalyst-supported stainless steel mesh was prepared by the following process:

[0051] Weigh 8 mol of aluminum chloride and add it into 5 L of methanol and stir evenly to obtain solution A. Mix 1L of deionized water and 1L of methanol, add hydrochloric acid to adjust the pH to 3, add 0.8mol of copper sulfate, 1mol of nickel sulfate, and 1.5mol of urea solid powder for dissolution to obtain solution B. Solution A and solution B were mixed and sonicated for 1 hour to form a gel. Dry at 80°C for 24 hours to obtain a xerogel. After being processed into powder with a grinder, it was placed in a muffle furnace and calcined at 450°C for 5 hours to obtain a dry powder. Mix 50g of acrylic powder with dry powder and stir evenly, then put it into an electrostatic powder spraying chamber, and spray the charged powder onto the surface of a 30-mesh stainless steel mesh under a pressure of 1.1 atmospheres to form a coating. Treat at 180°C for 30 minutes to obtain a stainless steel...

Embodiment 2

[0062] Catalyst-supported stainless steel mesh was prepared by the following process:

[0063] Weigh 10 mol of aluminate and add into 5L of absolute ethanol and stir evenly to obtain solution A. Add 1 mol of manganese acetate, 1 mol of copper chloride, 1 mol of nickel sulfate, and 2 mol of ammonium carbonate solid powder into a mixed solution of 2 L of deionized water and 2 L of absolute ethanol (add hydrochloric acid to adjust the pH to 3) and dissolve to obtain solution B. Solution A and solution B were mixed and sonicated for 1.5 hours to form a gel. Dry at 80°C for 24 hours to obtain a xerogel. After being processed into powder with a grinder, it was placed in a muffle furnace and calcined at 480 °C for 5 hours to obtain a dry powder. Mix 60g of epoxy resin powder with dry powder and stir evenly, then put it into an electrostatic powder spraying chamber, and spray the charged powder onto the surface of a 30-mesh stainless steel mesh under a pressure of 1.1 atmospheres to...

Abstract

The invention discloses a catalyst loading device for degrading macromolecular organic compounds through electron beam irradiation and relates to sewage treatment. The device comprises a metal net, wherein aluminum oxide which is co-doped and modified by metal ions manganese, copper and nickel and non-metal ion nitrogen is loaded on the metal net and serves as an active component; the molecular formula of the active component is Al2OuNvMnxCuyNiz, ugt; 3, 0lt; vlt; vlt; 1, 0lt; xlt; 1, 0lt; yt; Yt; 1, 0lt; zlt, zlt; 1. The catalyst loading device is placed at the rear end of the general electron beam irradiation jet device, and the organic sewage is in contact with a catalyst in the electron beam irradiation process of the organic sewage. The added catalyst device can significantly improve the treatment effect of the electron beam irradiation process and reduce the treatment cost. The adopted multi-element synergistic catalyst can greatly improve the biodegradability of sewage under the action of electron beam irradiation, provides a carbon source for a subsequent biochemical unit, and improves the degradation effect of biochemistry on organic pollutants.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a catalyst loading device for degrading macromolecular organic compounds by electron beam irradiation. Background technique [0002] There are high-concentration and refractory high-molecular organic substances in the sewage and landfill leachate of chemical industry parks. At present, the commonly used treatment process in the industry adopts the treatment process of biochemistry + chemical oxidation + membrane filtration, which has large investment, high treatment cost and low treatment efficiency. In particular, the concentrated water generated during the membrane treatment process is usually recharged to the raw water for secondary treatment, and then the above-mentioned process is repeated; after a period of operation, the refilled concentrated water reduces the treatment effect of the overall process, resulting in membrane concentration. The concentration of concentrated wa...
