A small aerator for sewage treatment

Abstract

The invention relates to the field of wastewater treatment equipment, particularly to a mini-type aeration machine for wastewater treatment. The mini-type aeration machine comprises a machine body, a water inlet pipe, a water outlet pipe and an aeration device, wherein the whole machine body adopts a revolving body structure; the water inlet pipe is positioned at the upper part on the left side of the machine body; the water outlet pipe is positioned at the upper part on the right side of the machine body; the aeration device is positioned in the machine body in a penetrating manner; the machine body comprises a cylindrical cavity and an elliptical cavity connected with the lower part of the cylindrical cavity; a cylindrical sludge outlet is formed in the lower end of the elliptical cavity; a sludge sealing cover is connected to the outer side of the sludge outlet; an electromagnetic valve is mounted on each of the water inlet pipe and the water outlet pipe; the aeration device comprises a main pipe, gas-distributing pipes, aeration elements, an air blower and a storage battery; a sieve plate and an activated carbon layer are arranged in the water outlet pipe. The occupied space of aeration can be effectively reduced, and meanwhile the sewage aeration requirements of families and mini-type wastewater treatment environment are met.

Description

technical field [0001] The invention relates to the field of sewage treatment equipment, in particular to a small aerator for sewage treatment. Background technique [0002] Sewage treatment process: [0003] Primary treatment is physical treatment: the raw sewage passing through the coarse grid is lifted by the sewage lift pump, passes through the grid or sand filter, and then enters the grit chamber, and the sewage separated from sand and water enters the primary sedimentation tank; [0004] Secondary treatment: the effluent of the primary sedimentation tank enters the biological treatment equipment, there are activated sludge method and biofilm method, and the reactor of the activated sludge method includes aeration tank, oxidation ditch, etc., and the biofilm method includes biological filter, biological Turntable, biological contact oxidation method and biological fluidized bed, the effluent of the biological treatment equipment enters the secondary sedimentation tank,...
