Method for producing natural mineral adsorption filter element

Abstract

The invention discloses a method of preparation natural mineral adsorption filtration core. Key point of technical project is: selecting natural mineral adsorption filtration agent as raw material, moistening with water, pressing to cylindrical porous object, airing, roasting, cooling and getting the product. There is interconnection labyrinth-type micropore in the filtration core which has the excellence of large specific surface area, fast filtration velocity, good adsorption capability, high film suspension efficiency and strong sewage stop ability. The labyrinth-type micropore is benefit for organic bacterium growth and reproduction and decreases ammonia and nitrogen content of breed water body. The oxygen content of breed water body can increase by aeration process. The natural mineral filtration core can adsorb diversified harmful substance generated by organism metabolism and heavy metal, and is adapted for breed water purifying and other water quality process.

Description

Technical field: [0001] The invention relates to an adsorption filter core, in particular to a production method of a natural mineral adsorption filter core. Background technique: [0002] In order to improve the production efficiency and economic benefits of aquaculture water, most of the farms adopt high-density intensive cultivation. The balance ability of the water ecosystem is limited. High-density intensive cultivation and a large amount of feeding can easily cause insufficient dissolved oxygen in the water body, resulting in a large amount of organic matter in the water. , the algae grow too fast, the water color changes greatly, the pH value is unstable, and the ammonia nitrogen content exceeds the standard. In order to maximize the production capacity of the limited aquaculture water body, it is necessary to maintain good water quality environmental conditions, which must solve the water quality pollution caused by the corruption of organic matter such as loose, res...

Problems solved by technology

[0006] 1. The porous ceramic blank contains attapulgite rods. After being sintered at a constant temperature in the range of 1000-1500°C for 3-5 hours in the kiln, the crystal structure of the attapulgite rods has been severely damaged, which greatly reduces the attapulgite. Adsorption performance

[0007] 2. After the cement, gypsum, quartz sand and attapulgite in the ingredients are put into the kiln and sintered at a constant temperature within the range of 1000-1500 °C for 3-5 hours, they are in a molten state, and the voids formed by the bubbles produced by the foaming agent It will be greatly reduced, so it will cause poor sewage interception ability, low film-hanging efficiency, which is not conducive to the growth and reproduction of biological bacteria, and cannot effectively reduce the ammonia nitrogen content of aquaculture water.
