Embodiment 1

[0012] The volume ratio of each component of the composite preparation of the present embodiment is: Rhodospirillum: Bacillus natto: Nocardiella streptospora: Lactobacillus is 1: 1: 1: 1

[0013] The use method of the microbial preparation for efficiently treating urban lake water pollution of the present invention is: according to the water depth per mu per meter, mix 1-2 kg of the preparation with 5 kg of zeolite powder for 1 hour, and then directly sprinkle it in the lake water.

[0014] The application of this embodiment to the treatment of urban lake water has a good effect. Compared with other microbial preparations on the market for urban lake water treatment, under the premise of the same dosage and treatment time, the phosphorus is 2 times lower, the nitrogen is 4.3 times lower, and the sulfur is 3.5 times lower. Its speed of decomposing sludge in water is 4.5 times that of the market.

Embodiment 2

[0016] In this embodiment, the volume ratio is:

[0017] The ratio of Nitrosospirillum: Rhodospirillum: Bacillus natto: Nocardioides streptospora: Lactobacillus is 2:3:3:3:3.

[0018] The use method of the microbial preparation for efficiently treating urban lake water pollution of the present invention is: according to the water depth per mu per meter, mix 1-2 kg of the preparation with 5 kg of zeolite powder for 1 hour, and then directly sprinkle it in the lake water.

[0019] The application of this embodiment to the treatment of urban lake water has a good effect. Compared with other microbial preparations on the market for urban lake water treatment, under the same premise of the same dosage and treatment time, the phosphorus is 2.5 times lower, the nitrogen is 4 times lower, and the sulfur is 3.8 times lower. Its speed of decomposing sludge in water is 4 times that of the market.

Embodiment 3

[0021] In this embodiment, the volume ratio is as follows: Nitrosospirosis: Rhodospirillum: Bacillus natto: Nocardia streptospora: Lactobacillus is 8:10:15:5:10.

[0022] The use method of the microbial preparation for efficiently treating urban lake water pollution of the present invention is as follows: according to the water depth per mu per meter, mix 2 kg and 5 kg of zeolite powder of this preparation for 1 hour, and then directly sprinkle it in the lake water.

[0023] The application of this embodiment to the treatment of urban lake water has a good effect. Compared with other microbial preparations on the market for urban lake water treatment, under the same premise of the same dosage and treatment time, the phosphorus is 2.7 times lower, the nitrogen is 4.7 times lower, and the sulfur is 4 times lower. Its speed of decomposing sludge in water is 4.9 times that of the market.

Abstract

The invention discloses a microbiological preparation for efficiently treating municipal lake water pollution. The microbiological preparation is prepared from nitrosospira, rhodospirillum, bacillus subtilis natto, kitasatospora phosalacinea and lactobcillus in a volume ratio of 0-10 to 5-15 to 5-15 to 5-15 to 5-15. The microorganism selected and cultured by the invention has the capability of being rapidly multiplied and developed into a dominant microflora under the municipal lake water environment; and each strain can independently and cooperatively decompose eutrophic ingredients in the municipal lake water and can make certain eutrophic ingredients which are difficult to decompose in a normal state easy to decompose. The microbiological preparation has the advantages of purifying thewater quality well, improving the substrate, optimizing the biological environment, saving the biological environment from damage, having obvious effect on water raising, water retention, water colorstabilization, treatment of turbid water, water concentrate, red water, black water, bottom odourization and algae aging and regulation and stabilization of pH value of the water body and making the lake water clear and odorless rapidly, along with simple using method, low cost, obvious effect, no secondary pollution.

Description

technical field [0001] The invention relates to a microbial preparation, in particular to a microbial preparation for treating urban lake water pollution. Background technique [0002] With the increasing shortage of fresh water resources and increasing water demand, many cities are in a state of water shortage, while urban lake water pollution is wasting fresh water resources on a large scale. Since urban lake water is a closed and slow-flowing water body with poor fluidity, it is easy to become a receiver of domestic sewage, industrial sewage, rainwater and garbage. Since urban lake water is still water, one of its characteristics is that the dissolved oxygen is less and uneven. With the development of the city, factories are gradually moving out, and the treatment of industrial sewage is increasingly strengthened, so the pollution of industrial sewage to urban lake water is gradually reduced. However, with the increase of urban population, the problem of domestic sewage...
