Abstract

The invention belongs to the technical field of methane desulfurization, and particularly relates to a methane biodesulfurization method. The methane biodesulfurization method comprises the following steps that: a circulating liquid containing desulfurizing bacteria is sprayed down by a spraying head at the top part of a desulfurization tower, methane is blown into a gas inlet pipe from the lower part of the desulfurization tower, and is fully contacted with the circulating liquid in the middle filler, the desulfurizing bacteria contained in the circulating liquid oxidizes and removes hydrogen sulfide in the methane by the action of biological oxidation, wherein 2.0-2.5L methane liquid is added into each cubic meter of circulating liquid every day. The methane biodesulfurization method has the characteristics that the control is convenient, the operation is simple, and the desulfurization efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of biogas desulfurization, and in particular relates to a biogas desulfurization method. Background technique [0002] Raw materials for biogas fermentation, such as livestock and poultry waste, high-concentration industrial organic wastewater, residual sludge from urban sewage plants, crop straw, and organic waste, are all biomass materials, which contain a considerable amount of organic or inorganic sulfur. It is converted into hydrogen sulfide during the process, so the biogas contains a certain amount of hydrogen sulfide. For example, the biogas fermented with chicken manure as raw material contains about 5000ppm hydrogen sulfide. Hydrogen sulfide not only has a strong corrosive effect on combustion power equipment and metal pipes, but also causes deterioration of lubricating oil and accelerates engine wear. After biogas is burned, hydrogen sulfide is converted into sulfur oxides (SO x ) and released i...
