Problems solved by technology

[0003] In the purification process of aquaculture water, various filter plates, filter blocks, filter elements, filter ceramics and filter rings have been used to purify water. Most of these filter materials are made of quartz sand, steel mesh, Composed of raw materials such as plastics and plant fibers, in practical applications, the adsorption and filtration performance is poor, and the film-hanging efficiency is low, which is not conducive to the growth and reproduction of biological bacteria, and cannot effectively reduce the ammonia nitrogen content of aquaculture water.

Embodiment Construction

[0025] Below in conjunction with embodiment, the present invention will be further described:

[0026] 1. Acidification treatment:

[0027] ①Acidification treatment of zeolite:

[0028] The zeolite is pulverized first, and the particle fineness is controlled at 0.5-0.8 mm; the preparation of dilute sulfuric acid includes the following components by weight percentage: 4% sulfuric acid with a concentration of 98%, and 96% water; the ingredients for acidification treatment include The following components: zeolite 60%, dilute sulfuric acid 40%; dilute sulfuric acid is slowly added to the zeolite for acidification treatment, and after stacking for 24 hours, it is extruded into flakes through an extruder, and the thickness of the flakes is controlled at 2 to 3 mm, and drying, the water content of the sheet after drying should be less than 15%.

[0029] ②Acidification treatment of attapulgite clay:

[0030] First, the attapulgite clay is crushed, and the particle fineness is cont...

Abstract

The invention discloses a natural mineral adsorption filtration agent, which comprises acidified zeolite, acidified attapulgite clay, acidified bentonite, acidified kieselguhr, volcanic rock and high-alumina clay. The preparation method of filtration agent is mixing, disintegrating, screening and packaging raw material to finished product. The filtration agent particles have rough surface, a lot of micropore inside, light specific gravity, large specific surface area and good adsorption capability, and are main raw material for preparing forming filtration material such as filtration plate, filtration block, filtration core, filtration pottery slice and filtration ring.

Description

Technical field: [0001] The invention relates to an adsorption filter, in particular to a natural mineral adsorption filter. 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, residual bait and excrement, and red...
