Embodiment 1

[0020] 80% of attapulgite, 14% of activated carbon, 1% of water glass, and 5% of iron oxide powder (mass ratio) were mixed respectively, and pellets with a particle diameter of 2-3 mm were prepared with a disc granulator. Put the samples in a tray to dry naturally for 24 hours, put them in a ceramic crucible, heat up to 500 °C in a reaction kettle, heat and dry for 2 hours, then cool to room temperature naturally to make the required material. Load the material into the shot blast gun. After the equipment is installed in place, evenly coat a layer of glass glue mixed with magnetic powder on the inner wall; before the glass glue is dry, spray the prepared pellets evenly on the inner wall of the equipment with a shot blasting gun. That is to say, the installation process of the material inside the device is completed.

Embodiment 2

[0022] 70% of attapulgite, 20% of activated carbon, 1.2% of water glass, and 8.8% (mass ratio) of iron oxide powder are mixed respectively, and pellets with a particle size of 2-3 mm are prepared with a disc granulator. Put the sample in a tray to dry naturally for 24 hours, put it in a ceramic crucible, heat up to 600 °C in a reaction kettle, heat and dry for 2 hours, and then cool it down to room temperature naturally to make the required material. Load the material into the shot blast gun. After the equipment is installed in place, evenly coat a layer of glass glue mixed with magnetic powder on the inner wall; before the glass glue is dry, spray the prepared pellets evenly on the inner wall of the equipment with a shot blasting gun. That is to say, the installation process of the material inside the device is completed.

Embodiment 3

[0024] 60% of attapulgite, 25% of activated carbon, 1.5% of water glass, and 13.5% (mass ratio) of iron oxide powder are mixed respectively, and pellets with a particle size of 2-3mm are prepared with a disc granulator. Put the sample in a tray to dry naturally for 24 hours, put it in a ceramic crucible, heat up to 650°C in a reaction kettle, heat and dry it for 2 hours, and then cool it down to room temperature naturally to make the required material. Load the material into the shot blast gun. After the equipment is installed in place, evenly coat a layer of glass glue mixed with magnetic powder on the inner wall; before the glass glue is dry, spray the prepared pellets evenly on the inner wall of the equipment with a shot blasting gun. That is to say, the installation process of the material inside the device is completed.

Abstract

The invention discloses a spraying material, a preparation method and a using method thereof. The spraying material comprises granular particles prepared by mixing attapulgite, active carbon, water glass and ferric oxide powder. The spraying material can be adhered into the inner wall of equipment, and overcomes the disadvantage that the inner wall of original equipment is difficult for film formation. The material is adhered onto the inner wall of the equipment, and after the material is in sufficient contact with sewage, the function of biological film formation can be realized, the quantityof microorganisms inside the equipment is increased, and the sewage treatment capacity of the equipment is improved.

Description

technical field [0001] The application relates to a spraying material, a preparation method and a use method thereof. Background technique [0002] At present, my country's rural sewage treatment mostly adopts the mode of biological treatment technology or the combination of biological treatment technology and ecological treatment technology. The most effective way to treat domestic sewage in villages and towns is to use low-cost small and medium-sized sewage treatment equipment. The research hotspots of this kind of water treatment equipment mainly focus on the application of anaerobic process, low energy consumption process and utilization of renewable energy. The equipment has the advantages of small footprint and high decontamination efficiency, and can save construction and operating costs, and is easy to manage. [0003] The microorganisms in the integrated equipment mostly adopt the method of microorganism immobilization. Immobilization refers to the use of physica...
