preparation example Construction

[0093] On the other hand, the present application also relates to a preparation method of a composite bacterial agent, comprising:

[0094] Candida, Bacillus megaterium, Sphingobacterium thalpophilum, Rhizoblum radiobacter, Bacillus amyloliquefaciens and Lactobacillus plantarum plantarum) at least four or at least five, cultured respectively; and obtaining the respective cultures of the strains, and mixing the cultures according to the above combination to obtain the composite microbial agent;

[0095] Optionally, the above culture is liquid culture, semi-solid culture or solid culture.

[0096] In one embodiment, the four strains of Bacillus megaterium, Rhizobium radiata, Bacillus amyloliquefaciens and Sphingobacterium mesophilus are cultured separately; and respective cultures of said strains are obtained, and said The cultures are mixed according to the above combination to obtain the composite microbial agent.

[0097] In one embodiment, the four strains of Candida, Baci...

Embodiment 1

[0173] The basic conditions of the water quality of the polluted water body in this embodiment are as follows: the ammonia nitrogen is 1.32 mg / L, the total phosphorus is 0.264 mg / L, the COD is 59.8 mg / L, and the chroma is 50.

[0174] Processing time: July 2014

[0175] Fermentation culture of Candida tropicalis, fermentation culture of Bacillus megaterium, fermentation culture of Mesophilic Sphingobacterium, fermentation culture of Rhizobium radiata, fermentation culture of Bacillus amyloliquefaciens and fermentation culture of Lactobacillus plantarum Mixed at a ratio of 2:1:1:1:1:2 to make a composite microbial agent.

[0176] Prepare 5 plastic buckets, each plastic bucket is filled with 100 liters of polluted water, the control group is not treated, and the remaining 4 buckets are added with compound bacteria according to 0.1%, 0.5%, 1% and 2% of the volume of the polluted water to be treated. The agents were labeled as treatment group 1, treatment group 2, treatment group...

Embodiment 2

[0183] The basic conditions of the water quality of the polluted water body in this embodiment are as follows: the ammonia nitrogen is 1.87 mg / L, the total phosphorus is 0.176 mg / L, the COD is 184 mg / L, and the chroma is 70.

[0184] Processing time: August 2014

[0185] Fermentation culture of Candida tropicalis, fermentation culture of Bacillus megaterium, fermentation culture of Mesophilic Sphingobacterium, fermentation culture of Rhizobium radiata, fermentation culture of Bacillus amyloliquefaciens and fermentation culture of Lactobacillus plantarum Mixed at a ratio of 2:1:1:1:1:2 to make a composite microbial agent.

[0186] Prepare 4 plastic barrels, each plastic barrel is filled with 100 liters of polluted water, the control group does not do any treatment, 1 of the treatment group is added with 0.5% of the volume of the polluted water to be treated with a compound bacterial agent, and 2 of the treatment group are inoculated with aquatic plants - Phoenix Indigo (water ...

Abstract

The invention provides a composition, a composite bacterium agent and application thereof. The composition or the composite bacterium agent contains the combination of at least four or more than four strains in candida, bacillus megatherium, sphingobacterium thalpophilum, rhizobium radiobacter, bacillus amyloliquefaciens and lactobacillus plantarum. The application includes the water body pollution control.

Description

technical field [0001] This application belongs to the technical field of environmental restoration. Specifically, the present application relates to a composition or a composite bacterial agent for controlling water body pollution. Background technique [0002] The water bodies of lakes and large artificial ponds are mostly static or slow-flowing water bodies with poor fluidity. There are problems such as easy pollution of water bodies and poor self-purification ability. Coupled with the influence of residents' lives and fish in the water, it is very easy to cause the increase of suspended solids in the water, turbidity, etc. Increased temperature, organic matter, bacteria and E. coli content increased. In summer, as the temperature rises, a large amount of algae will grow in water rich in elements such as N and P. The abnormal reproduction of algae will destroy the ecological balance of the water body, and the chroma of the water body will become green and even black and ...
