General Test and Research on Extracting Marsh Gas at the Bottom of Lakes, Rivers and Ponds

Mire at the bottom of lakes, rivers and ponds is constantly fermenting marsh gas and absorbing a lot of marsh gas. Extracting marsh gas as energy has some economic value. It can reduce the smelly and harmful gas H₂S and stop CH₄, with high greenhouse effect, from escaping into the air. It can also improve water self-purification and water quality.
