摘要

A system for treating an anaerobic treatment solution, the system including: a solid/liquid separator provided with a filtering medium immersed in an anaerobic treatment solution; a gas/liquid separator in which filtrate having permeated through the filter medium is present and gas is retained in a gas-phase section in the upper section of the filtrate; a filtrate flow path in communication with a filtrate extraction side of the filter medium and the gas-phase section of the gas/liquid separator; and a first gas flow path that communicates with the gas-phase section of the gas/liquid separator and is provided with a depressurizing means for depressurizing the gas-phase section.
