Description

technical field

[0001] The invention relates to a method for cultivating COD-degrading bacteria. Background technique

[0002] In terms of environmental pollution control, COD-degrading bacteria are usually used to reduce COD for treatment. The disadvantages are: the effect is not ideal, and how to clean and effectively remove it is still in the research stage. The search did not find relevant literature. Contents of the invention

[0003] For overcoming the defect of prior art, the invention provides a kind of cultivation method of COD degrading bacteria, technical scheme of the present invention is:

[0004] A method for cultivating COD-degrading bacteria, comprising the following steps:

[0005] (1) Prepare nutrient agar medium, the specific preparation method is as follows: take 10 parts of peptone, 5 parts of beef extract powder, 18 parts of agar powder, 5 parts of sodium chloride, mix according to the proportion, heat in a microwave oven after mixing, Heating time...

Examples

Embodiment

[0022] Example: Add the activated COD-degrading bacteria into the liquid medium, wherein the weight ratio of the COD-degrading bacteria and the liquid medium is 1:10, in a constant temperature incubator at 30°C, after cultivating for 24 hours, measure the COD in the medium In the blank sample, the content of COD is 0.283g / L, after adding the COD degrading bacteria, the content of COD is 0.086g / L.
