The present invention relates to a biogas purification system. The present invention relates to a biogas separation and purification system including: a pressure tank that performs mixing and pressurization so that biogas is dissolved in purified water; and a separation and purification tower that includes a separation tank which has a lower end portion storing purified water, a diffuser which is configured to be in the lower end portion of the separation tank and allows the biogas-dissolved purified water flowing in from the pressure tank to be diffused into micro bubbles, a purification gas outflow line which discharges the methane captured in an upper portion of the separation tank to the outside, and a treated water outflow line in the lower end portion of the separation tank which discharges purified water to the outside, wherein purification target gas containing carbon dioxide and hydrogen sulfide is dissolved. |
