preparation example Construction

[0027] The invention also discloses a preparation method of a compound microbial preparation for controlling algae, which includes the following steps: inoculating Enterobacteriaceae, Bacillus subtilis, Bacillus colloidus, photosynthetic bacteria and / or nitrobacteria into the medium for laboratory culture respectively , the bacteria can grow well after about 5-7 days of culture.

[0028] The cultured strains are divided into alginolytic bacteria, viscous bacteria and water purification bacteria according to their functions, and the mother liquor expansion fermentation is carried out respectively. Under the condition of 28-32 ℃, aerated fermentation culture. Generally, after 5-7 days, the fermentation is completed and can be used as seeds for large-scale production.

[0029] For the fermented seeds, large-scale fermentation production is carried out, generally for 6-8 days.

[0030] Finally, the bacteria solution produced by large-scale fermentation can be mixed according to ...

Abstract

The invention discloses a composite microbial preparation and application of the same in treatment of water body with algal bloom. The composite microbial preparation comprises algicidal bacteria, a viscous bacterium and water-purifying bacteria, wherein the algicidal bacteria comprise enterobacterium and / or bacillus subtilis, the viscous bacterium is bacillus mucilaginosus, and the water-purifying bacteria comprise a photosynthetic bacterium and / or a nitrite bacterium. A preparation method for the composite microbial preparation comprises a first step of separately culturing each bacterium and a second step of culturing all the bacteria mixed in proportion. The invention has the following advantages: separate culturing enables each bacterium to grow in a most effective way, and application of a mixture of the separately cultured bacteria gives full play to effect of each bacterium in the alga-controlling composite microbial preparation; the composite microbial preparation can effectively overcome the problem of debated algicidal effect caused by current impact on the bacteria and achieves alga-removing effect as well as water purifying effect, especially a removal effect on elemental nitrogen in the water body; and a breakthrough is made to the limitation that a traditional microbial preparation is only applicable to a hydrostatic water body with a small area, and the composite microbial preparation is applicable to rivers, lakes and regenerated water bodies.

Description

technical field [0001] The invention belongs to the field of environmental protection and ecological restoration, and more specifically relates to a composite microbial preparation and its application in water body treatment of algal blooms. Background technique [0002] The main supporting industries in my country are agriculture and industry. Pollutants enter the river and lake water system with the runoff of rainwater, which leads to the increase of nutrients such as nitrogen and phosphorus in the river and lake, and the eutrophication of the water body. With the development of industry and agriculture and the seriousness of water pollution and eutrophication caused by global warming, water pollution and algal blooms have occurred in many waters in my country, seriously affecting the use of water bodies and endangering aquatic organisms and aquaculture. , Some areas directly affect the safety of drinking water for residents. [0003] The main season for algae blooms is su...
