Beschreibung
Zusammenfassung:	The utility model provides a biogas treatment system comprising a wet-process desulfurization tower, a decarbonization tower, a dryer and an inclined plate sedimentation tank, wherein the gas outlet of the wet-process desulfurization tower is communicated with the gas inlet in the lower part of the decarbonization tower; the gas outlet in the upper part of the decarbonization tower is communicated with the gas inlet of the dryer; a calcium hydroxide solution inlet is formed in the upper part of the decarbonization tower; the liquid outlet in the lower part of the decarbonization tower is communicated with the liquid inlet of the inclined plate sedimentation tank. Compared with the prior art, according to the biogas treatment system provided by the utility model, sulfur is obtained by virtue of the wet-process desulfurization tower, and calcium carbonate and bio-natural gas are obtained by virtue of the decarbonization tower, so that the recovery of three valuable resources namely sulfur, the bio-natural gas a
