FIELD: gas-lift apparatuses designed for treatment of three-phase systems: liquid-gas-solid body, mainly, sludge sediments of household and/or industrial sewage waters. SUBSTANCE: gas-lift apparatus has vertically installed body, process branch pipes for supply of initial mass and discharge of finished product and waste gas ate least one air-lift tube communicating through inlet branch pipe installed on body bottom with internal space of said body. Air-lift tube lower part has branch pipe for supply of oxygen-containing gas. Gas-lift apparatus additionally has the second body of the same volume communicating with the first body through outlet pipe of said air-lift tube. Said outlet pipe is installed in upper part of the second body. Branch pipe for discharge of waste gases is installed in upper part of the second body. Branch pipe for separation of finished product is installed in lower part of the second body. In this case, located in lower part of the second body is working member of mixer for mixing of reaction mass and branch pipe for supply of oxygen-containing gas from bottom side. Bodies are installed so that bottom of the second body is located above cover of the first body. It is advisable to install bodies coaxially. EFFECT: higher efficiency. 2 cl, 1 dwg
