specific Embodiment approach 1

[0013] Specific embodiment one: In the present embodiment, the antibacterial ceramsite is composed of 30 to 80 parts of carrier, 2 to 6 parts of molybdate, 0.01 to 2 parts of silver salt, and 0.01 to 2 parts of copper salt in parts by weight. 2-6 parts of nano-ZnO, 6-10 parts of sludge powder with a particle size of 0.05-1.0 mm, 3-8 parts of pore-forming agent, 0.08-2 parts of binder and 10-20 parts of glaze-forming agent Made by mixing, drying, grinding, calcining and regrinding.

[0014] The carrier is composed of 50-800nm ​​(nanometer or submicron) tourmaline, zeolite and shale with a particle size of 0.1-30 μm, and the mass ratio of tourmaline, zeolite and shale is 4-8:1-4: 1. Described molybdate is ammonium molybdate. Described silver salt is silver sulfate or silver chloride. Described copper salt is copper sulfate or copper nitrate. The pore forming agent is CS. The binder is SF. The glaze-forming agent is a low-temperature glaze.

[0015] The sludge powder is ob...

specific Embodiment approach 2

[0017] Specific embodiment two: the difference between this embodiment and specific embodiment one is that antibacterial ceramsite is composed of 35 to 65 parts of carrier, 3 to 5 parts of molybdate, 0.1 to 1 part of silver salt, 0.1 parts by weight of antibacterial ceramsite ~1 part of copper salt, 3~5 parts of nano ZnO, 7~9 parts of sludge powder with a particle size of 0.05~1.0mm, 4~6 parts of pore forming agent, 0.1~1.5 parts of binder and 12 ~18 parts of glazing agent are prepared by mixing, drying, grinding, calcining and regrinding. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0018]Specific embodiment three: the difference between this embodiment and specific embodiment one is that the antibacterial ceramsite is composed of 50 parts of carrier, 4 parts of molybdate, 0.5 part of silver salt, 0.5 part of copper salt, 4 parts by weight. It is prepared by mixing, drying, grinding, calcining and regrinding of 1 part of nano-ZnO, 8 parts of sludge powder with a particle size of 0.05-1.0mm, 5 parts of pore forming agent, 1 part of binder and 15 parts of glaze forming agent. . Others are the same as in the first embodiment.

Abstract

The present invention relates to bacteriostat, and is one kind of bacteriostatic haydite and its making process. The bacteriostatic haydite is made with carrier, molybdenate, silver salt, copper salt, nanometer zinc oxide, sludge powder of 0.05-0.08 mm, pore forming agent, adhesive and glaze forming agent. Its making process includes the following steps: 1. adding the carrier into deionized water and regulating pH value; 2. adding molybdenate, silver salt, copper salt, nanometer zinc oxide and dispersant through lucifugous stirring; 3. decompression filtering to separate, washing with deionized water, and stoving; 4. adding sludge powder, pore forming agent, adhesive and glaze forming agent, and grinding after adding deionized water; 5. forming and naturally drying; and 6. calcining. The bacteriostatic haydite with carrier of tourmaline, zeolite and shale has high molybdenum carrying amount and high bacteriostatic effect.

Description

technical field [0001] The invention relates to a bacteriostatic agent and a preparation method thereof. Background technique [0002] In recent years, with the accelerated development of the national economy, the pollution of industrial wastewater, especially sulfate wastewater, has been quite serious. The groundwater of many large cities in my country has been polluted by sulfates to varying degrees. Discharge of sulfate-containing acidic wastewater directly into the water body without treatment will acidify the receiving water body, reduce the pH value of the water body, endanger aquatic organisms, and cause potential corrosion; this type of acidic wastewater will also damage the soil structure and reduce crop yields. In particular, the sulfate-reducing bacteria in the oil field proliferate in large numbers, producing a large amount of sulfide, which has brought serious harm to the oil field production, and has become a very noticeable problem in the oil field production...
