Embodiment 1

[0016] The preparation of embodiment 1 controlled-release probiotics

[0017] 1. Seed culture of Bacillus subtilis

[0018] The seed medium of Bacillus subtilis is: 0.5% sucrose, MgSO 4 0.02%, CaCO 3 0.5%, K 2 HPO 4 0.02%, pH7.0~7.2. The volume of 500ml triangular bottle is 100ml, sterilized at 121°C for 20 packs, cooled and then connected to a slope ring, cultured on a shaking table, the rotating speed of the shaking table is 200 rpm, and the cultivation temperature 37°C, incubation time 28 hours.

[0019] 2. Production of Bacillus subtilis

[0020] The liquid medium of Bacillus subtilis is 1% sucrose, 0.02% yeast extract, MgSO 4 0.01%, Na 2 HPO 4 0.01%, CaCO 3 0.1%, pH 7.0. After the fermenter was sterilized for 1 hour in advance, pour the culture medium into a 1-ton tank, fill with 800L fermentation broth, sterilize at 121-125°C for 1 hour, cool to 30-35°C, and inoculate.

[0021] The fermentation conditions are as follows: the fermentation temperature is 37°...

Embodiment 2

[0026] The preparation of embodiment 2 controlled-release probiotics

[0027] The preparation method is the same as that described in Example 1, except that the ratio of the composite bacteria is different. Controlled release Bacillus subtilis powder 60%, Bacillus cereus 15%, Lactic acid bacteria 10%, Yeast 15%.

Embodiment 3

[0028] The preparation of embodiment 3 controlled-release probiotics

[0029] The preparation method is the same as that described in Example 1, except that the ratio of the composite bacteria is different. Controlled release Bacillus subtilis powder 75%, Bacillus cereus 12%, Lactic acid bacteria 7%, Yeast 6%.

Abstract

The invention which discloses a controlled release microecological preparation for water quality improvement and a preparation method thereof belongs to the biotechnological field, and concretely relates to the preparation method of the controlled release microecological preparation for water quality improvement. The microecological preparation treats bacillus subtilis as a main flora and Bacillus cereus, lactics, and microzyme as auxiliary floras. By adopting the composite microbial preparation to process water, organic mud can be effectively degraded, harmful substances of ammonia, nitrites, hydrogen sulfide and the like in water can be absorbed and utilized, the breeding of harmful microbes and harmful algae can be inhibited, the microecological environment of water can be balanced, and the health growth of aquatic organisms can be promoted, so the microecological preparation of the present invention is more economical and is more suitable for popularization than common microecological preparations.

Description

technical field [0001] The invention relates to a microecological preparation for improving water quality and a preparation method thereof, in particular to a controlled-release microecological preparation. technical background [0002] At present, my country's water environment pollution is quite serious. Among the seven major river systems in the country, about 40% of the water quality is inferior to the fifth-class standard; 75% of the lakes in the country have varying degrees of eutrophication; The nearby sea area is seriously polluted, the frequency of red tides has increased, and the area has expanded. The pollution of water environment has directly threatened the safety of urban drinking water and people's health. Therefore, it is an urgent need for social and economic development and ecological environment construction to restore polluted rivers and lakes. [0003] Microbial water purification is a biological product specially used for water purification, sewage tre...
