Abstract: An anaerobic purification device for purification of wastewater, the anaerobic purification device comprising: a reactor tank (10) configured to, when in operation, have a sludge blanket formed at the bottom part; a fluid inlet (12) for, in operation, introducing influent into the reactor tank, the fluid inlet located in the lower section of the reactor tank (10); at least one gas-collecting system (13); at least one gas-liquid separation device (30); at least one riser pipe (22) connected to the at least one gas-collecting system (13) and discharging into the gas-liquid separation device (30); a downer pipe (24) connected to the gas-liquid separation device (30) and discharging into the bottom of the reactor tank (10); and a fluid outlet (16) comprising means for, in operation, varying the height of the fluid level (19) in the reactor tank within a predetermined range, the fluid outlet arranged at the upper section of the reactor tank (10); wherein the fluid level control means comprises: a fluid valve (15) configured to control the height of the fluid in the reactor tank within the predetermined range, a fluid level detector (17), a gas flow meter (33) configured to measure the production rate of gas in the anaerobic purification device, and a controlling unit configured to regulate the fluid valve (15) to vary the height of the fluid level in the reactor tank (10) based on at least one of the fluid level detected by the fluid level detector (17) and the gas production rate detected by the gas flow meter (33).
