Background

Biogas, also known as methane, is a combustible mixed gas produced by the fermentation of organic substances in an anaerobic environment by microorganisms, and the main components of the biogas are methane and carbon dioxide. The mixture of marsh gas and air can form explosive gas, if the concentration of marsh gas in air is 5.5-16%, explosion can occur under the condition of open fire. The methane explosion can generate high temperature, high pressure and shock wave, and toxic gas is discharged. The reason that the environment-friendly consciousness of surrounding residents is not strong is that the pipelines which originally flow sewage are filled with too much domestic garbage, the sewage is easy to form biogas after being blocked, the air in a longer sewer channel is not circulated, and the biogas is easy to be retained and accumulated to generate potential safety hazards.
