Detailed Description
The present invention will be further understood with reference to the following examples.
Example 1
Introducing the marsh gas containing hydrogen sulfide and carbon dioxide gas into a hydraulic gas storage tank filled with photosynthetic green sulfur bacteria aqueous solution. The microorganism is a photoautotrophic microorganism, which mainly absorbs light energy to perform photosynthesis to fix carbon dioxide, and in the process of fixing carbon dioxide, different inorganic substances such as hydrogen sulfide can be used as a hydrogen donor, and the reaction formula is as follows:
example 2
Introducing marsh gas containing hydrogen sulfide and carbon dioxide gas into a hydraulic pressure type gas storage tank filled with a Behcet sulfur bacterial solution, and introducing oxygen or air into the hydraulic pressure type gas storage tank to perform the following reaction:
2H2S+O→2S+2H2O
example 3 recovery of bacterial liquid
And (4) periodically discharging and recycling the treated bacteria liquid, and adding purified water and microorganism water solution after discharging so as to be continuously utilized, and repeating the steps. The recovered bacterial liquid applied to the soil can improve the physicochemical property of the soil, promote the growth of crops, and can play a role in purification and enhance photosynthesis when being put into a fishpond.
Example 4
The water pressure type methane storage tank is internally provided with a fluorescent lamp which can provide artificial light energy when solar light energy cannot be received.
