Abstract

The invention discloses a cycle type aerating device for domestic sewage. The device comprises a tank body, a fixing frame, an electric motor, a driving shaft, a stirring rod, an aerating board, aerating heads, a blower, a water outlet pipe and a water inlet pipe; the top of the tank body is fixedly connected with the fixing frame, the lower surface of the fixing frame is fixedly connected with the electric motor, the shaft extension end of the electric motor is fixedly connected with the driving shaft, the stirring rod is fixedly connected with the driving shaft, the left side wall of the tank body is rotatingly connected with a rotation shaft, a cam sleeves the left end of the rotation shaft, a cleaning grille is arranged below the cam, the left side of the tank body is provided with a circulating pipe, the bottom of the tank body is equipped with the aerating board, a left movable plate and a right movable plate are hinged to the upper surface of the aerating board, the tail ends of aerating blades are always floated on the water surface by utilizing buoyancy boxes, and aerating is performed on the surface-layer sewage; a water pump is started to enable the sewage to form cycles in the tank body, so that the aerating effect is improved; and the left movable plate and the right movable plate keep swinging left and right, and therefore the mixing of the sewage and air exhausted by the aerating heads is more uniform.

Description

technical field [0001] The invention relates to domestic sewage treatment equipment, in particular to a circulating domestic sewage aeration device. Background technique [0002] The aeration tank is a structure that uses the activated sludge method for sewage treatment. A certain sewage residence time is provided in the pool to meet the oxygen required by aerobic microorganisms and the mixing conditions for full contact between sewage and activated sludge. The aeration tank is mainly composed of three parts: the tank body, the aeration system and the water inlet and outlet. The pool body is generally built with reinforced concrete, and its planar shape is rectangular, square and circular; aeration is a means to make air and water come into strong contact, and its purpose is to dissolve oxygen in the air in water. There are two main types of aeration methods, mechanical aeration and blast aeration. However, the existing aeration tanks often have a single aeration structure...
