[0002] The buried domestic sewage treatment equipment is a modular and efficient sewage biological treatment equipment. It is a sewage biological treatment system with biofilm as the main purification body. It gives full play to the characteristics of anaerobic biological filter, contact oxidation bed and other biofilm reactors, such as high biological density, strong pollution resistance, low power consumption, stable operation and convenient maintenance, which makes the system have a broad application prospect and promotion value. When inoculating biogas bacteria, this type of equipment needs to take samples from the sludge sediment at the bottom of the sewer, manure pit and old biogas tank to increase the number of biogas bacteria and achieve the purpose of fermentation and biogas production as soon as possible.
