Problems solved by technology

The water quality of some farmers has seriously deteriorated, and the aquaculture parameters such as ammonia nitrogen, nitrite, and dissolved oxygen in the water continue to deteriorate; the degree of beneficial algae activity has been greatly reduced, the situation of aging and stagnant water has become increasingly serious, and photosynthesis has decreased, which is manifested within a day. The pH value does not change, or the change is very slight, which is not suitable for the life and growth of fish
It is precisely because of the continuous deterioration of the water quality environment and the frequent occurrence of fish diseases that farmers use a large number of drugs for prevention and control, especially the increase in the abuse of antibiotics, which accelerates the deterioration of water quality and has a negative impact on fish meat quality. The prevention and control of fish diseases brings greater difficulties

Embodiment 1

[0014] Embodiment 1: the preparation method of tilapia water quality improver, comprises the following steps:

[0015] 1) The preparation method of straw fermented product is as follows: mix 900 parts of straw with 30 parts of diammonium phosphate and 24 parts of bean cake powder, add 5 parts of fermentation bacteria agent, and then aerobically ferment to obtain straw fermented product. The prepared straw fermentation product is an environmentally friendly adsorbent, which contains a large number of micropores and has a large specific surface area. It has a strong adsorption effect on most of the organic pollutants that are difficult to remove in the water body, and can effectively improve the water quality. quality;

[0016] 2) The preparation method of molecular weight alkanol phosphate ester is: mix oleyl alcohol polyoxyethylene ether with phosphorus pentoxide at a mass ratio of 1:1, react at a temperature of 61°C for 2 hours, and divide phosphorus pentoxide into 3 times A...

Embodiment 2

[0018] Embodiment 2: the preparation method of tilapia water quality improver comprises the following steps:

[0019] 1) The preparation method of straw fermented products is as follows: mix 1200 parts of straw with 45 parts of diammonium phosphate and 32 parts of bean cake powder, add 8 parts of fermentation bacteria agent, and then add 0.01 part of isoamyl butyrate and 0.004 part of ethyl butyrate , followed by aerobic fermentation to obtain straw fermented product. The prepared straw fermentation product is an environmentally friendly adsorbent, which contains a large number of micropores and has a large specific surface area. It has a strong adsorption effect on most of the organic pollutants that are difficult to remove in the water body, and can effectively improve the water quality. quality; the added isoamyl butyrate and ethyl isobutyrate can increase the internal surface area of ​​the straw, reduce the crystallinity of cellulose and hemicellulose in the straw, and fac...

Embodiment 3

[0022] Embodiment 3: the preparation method of tilapia water quality improver comprises the following steps:

[0023] 1) The preparation method of straw fermented product is: mix 1100 parts of straw with 34 parts of diammonium phosphate and 27 parts of bean cake powder, add 6 parts of fermentation agent, and then aerobically ferment to obtain straw fermented product. The prepared straw fermentation product is an environmentally friendly adsorbent, which contains a large number of micropores and has a large specific surface area. It has a strong adsorption effect on most of the organic pollutants that are difficult to remove in the water body, and can effectively improve the water quality. quality;

[0024] 2) The preparation method of molecular weight alkanol phosphate ester is: mix oleyl alcohol polyoxyethylene ether with phosphorus pentoxide at a mass ratio of 2:1, and react at a temperature of 62°C for 2.5 hours, in which phosphorus pentoxide is divided into 4 Add once, an...

Abstract

The invention discloses a preparation method of a water quality improver for tilapia. The water quality improver is prepared from 49-62 parts of ethanol, 1-3 parts of polymerized sulfate, 4-7 parts ofa straw fermented product, 0.2-0.7 parts of chain alkyl alcohol phosphate with high molecular weight, 10-14 parts of bacillus subtilis and 8-11 parts of lactic acid producing faecalis by ultrasonic mixing. The preparation method has the following beneficial effects: the method is simple, raw materials are easily available, cost is low, and the prepared product can improve water quality effectively.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a preparation method of a tilapia water quality improver. Background technique [0002] With the rapid development of the aquaculture industry, especially the development of large-scale high-density aquaculture today, the proportion of aquaculture in the aquaculture industry is increasing. Due to the continuous expansion of market demand, the aquaculture density of aquaculture farmers is also increasing. With the continuous increase of aquaculture density, the deterioration of water quality cannot be ignored, mainly manifested in: water pollution caused by fish feces, and the impact of human domestic sewage and agricultural sewage, resulting in water quality deterioration. The water quality of some farmers has seriously deteriorated, and the aquaculture parameters such as ammonia nitrogen, nitrite, and dissolved oxygen in the water continue to deteriorate; the degree of benef...
