Embodiment 1

[0017] The cultivation of embodiment 1 bacillus

[0018] 1. Bacillus strains are isolated from the breeding sewage, and the conventional nutrient agar medium and nutrient broth medium are prepared.

[0019] 2. Culture of bacteria

[0020] Inoculate the bacillus strains on the slant of nutrient agar medium under aseptic conditions, and then culture them in an incubator at 37°C for 24 hours, and a layer of white round bacillus colonies with smooth edges can be seen. Aseptically inoculate the bacillus cultured in the nutrient agar medium into 100ml nutrient broth medium, shake well, and cultivate in a shaker at 37°C for 2-3 days, and set aside.

Embodiment 2

[0021] The cultivation of embodiment 2 nitrifying bacteria and nitrosifying bacteria

[0022] 1. The strains of nitrifying bacteria and nitrosifying bacteria are separated from the breeding sewage, and the conventional liquid culture medium of nitrifying bacteria and nitrosifying bacteria is prepared.

[0023] 2. Culture of bacteria

[0024] Inoculate the nitrifying bacteria and nitrosifying bacteria preliminarily separated from the aquaculture sewage into a 100ml test tube in a shaker at 20-28°C at 200 rpm, shake and culture for 3-5 days, and set aside.

Embodiment 3

[0025] The cultivation of embodiment 3 photosynthetic bacteria

[0026] 1. The photosynthetic bacteria strains are isolated from the breeding sewage, and the conventional photosynthetic bacteria solid and liquid culture medium are prepared.

[0027] 2. Culture of bacteria

[0028] Inoculate the photosynthetic bacteria strains on the photosynthetic bacteria solid medium under aseptic conditions, and then culture them in an incubator at 30°C for 24 hours under anaerobic conditions, and make the photosynthetic bacteria cultured on the photosynthetic bacteria solid medium sterile Inoculate into 100ml of photosynthetic bacteria liquid medium, culture at 30°C for 3-5 days under anaerobic conditions, and set aside.

Abstract

The invention relates to a method for purifying an aquaculture water body commonly by utilizing marine algae and microorganisms. According to the method, functional microorganisms of five different physiological groups, including bacillus subtilis, nitrifying bacteria, nitrite bacteria, photosynthetic bacteria and thiobacillus, are put into the aquaculture water body in a volume ratio of (1-5):(1-4):(1-6):(2-8):(1-5), and marine algae which is zostera marina or ulva is planted into the aquaculture water body at the same time. The method can be used for meeting the requirement for simultaneously purifying pollutant components in the aquaculture water body by utilizing marine algae and multiple bacteria.

Description

technical field [0001] The present invention relates to a method for biological purification of marine aquaculture water, in particular to a method for aquaculture water organisms in which marine algae are planted in the aquaculture water, and bacillus, nitrifying bacteria, nitrosifying bacteria, photosynthetic bacteria and sulfide bacteria are added to the aquaculture water. Purification method. Background technique [0002] The growing development of the aquaculture industry has improved people's living standards. China is the world's largest aquaculture country in terms of both aquaculture output and aquaculture scale. However, most aquaculture farmers in my country aim to pursue output and short-term economic benefits. The breeding density is too high, coupled with weak awareness of environmental protection, aquaculture diseases are increasing year by year. At the same time, most of my country's aquaculture industry is static water aquaculture, and high-density aquacult...
