Problems solved by technology

However, there are two problems in the practical application of titanium dioxide. One is that titanium dioxide has a wide band gap and can only absorb ultraviolet light with a wavelength less than 387nm, and this part of light energy only accounts for 4% of the solar energy reaching the ground. The artificial ultraviolet light source has the defects of high power consumption, expensive equipment, poor stability, etc., and the industrialization prospect is not good. Second, the traditional powdered titanium dioxide is prone to particle agglomeration, which affects the light utilization efficiency. big limit

Embodiment Construction

[0020] A kind of aquaculture water oxygen enhancer, prepared by the following method:

[0021] (1) Heat the vermiculite to 450°C for 1 hour, cool it down naturally, put it into 4 times the quality of water and soak it for 2 hours, then add alkyl dimethyl betaine with 10% of the total weight of the vermiculite, stir for 20 minutes, and filter Remove water to obtain organic expanded vermiculite for subsequent use;

[0022] (2) Wash the sunflower disc, dry and pulverize it, put it in a high-temperature furnace, heat it to 700°C under the protection of nitrogen, and carbonize it for 90 minutes. After cooling, take it out and pulverize it to obtain the carbonized material of the sunflower disc. Mix the carbonized material with 1mol / L The sodium hydroxide solution was mixed according to the ratio of material to liquid 1:4g / mL, then soaked for 30 minutes, then filtered out, washed with water and dried to obtain activated carbonized material;

[0023] (3) Mix boric acid and tetrabuty...

Abstract

The invention discloses an aquaculture water oxygen producer. The aquaculture water oxygen producer is prepared from the following raw materials: vermiculite, a disintegrating agent, sodium citrate, sodium percarbonate, alkyl dimethyl betaine, sunflower plates, boric acid, tetrabutyl titanate, urea and the like. On one hand, solid excreted organic matters such as fish and shrimps in water are degraded and the aquaculture water quality is improved, and on the other hand, the oxygen release speed is controlled via photocatalysis while the disintegrating speed of the oxygen producer in the water is regulated and controlled, long-time and sufficient feeding of the water can be guaranteed effectively, and high economic value is achieved.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to an oxygenator for aquaculture water and a preparation method thereof. Background technique [0002] The dissolved oxygen in natural water is generally in the range of 8-12mg / L, which can fully meet the oxygen demand for the normal growth of various fish. However, there are many factors that consume dissolved oxygen in water, such as the respiration of animals and plants, the oxidation and decomposition of organic matter and other reducing substances, etc., which make the dissolved oxygen in water far below the normal value. At the same time, with the continuous improvement of aquaculture technology and aquaculture costs, in order to pursue high yields, the amount of fish and shrimp stocking per unit water area is also increasing. However, high-density aquaculture is likely to cause low oxygen content in aquaculture ponds, especially in ponds. The area where the fish and shri...
