A bioelectrochemical device for synchronous sewage treatment and nitrogen and phosphorus recovery

Abstract

The invention discloses a bio-electrochemical device for a synchronous sewage treatment and nitrogen and phosphorus recovery. The device comprises a box body, fine mesh plates are fixedly arranged onthe left side and the right side in the box body respectively; the bottom sides of the fine mesh plates are respectively hinged with the top sides of the baffles; a rectangular through hole is formedin the bottom of the box; the lower ends of the baffles are movably arranged in the upper part of the box body, a motor is fixedly installed in the middle of the top side of the box body, the lower end of a motor rotating shaft penetrates through the top wall of the box body and is located in the box body, the lower end of the motor rotating shaft is fixedly connected with the upper end of a leadscrew, a rectangular ring is movably arranged in the upper portion of the box body, and the inner periphery of the rectangular ring is fixedly connected with the periphery of a nut. The structure is simple and the design is ingenious. A reaction tank cleaning device and a stirring device are combined, the occupied space of the device is reduced, meanwhile, the structure of the device is reduced, the cost is reduced, the reaction tank is divided into a stirring sedimentation area and a standing liquid discharging area, the standing time is shortened, actual requirements can be met, and the device is suitable for popularization.

Description

technical field [0001] The invention belongs to the field of sewage treatment devices, in particular to a bioelectrochemical device for synchronous sewage treatment and nitrogen and phosphorus recovery. Background technique [0002] With the increasing maturity of bioelectrochemical sewage treatment technology, bioelectrochemical devices for nitrogen and phosphorus recovery are widely used. The reaction tanks used in nitrogen and phosphorus recovery bioelectrochemical devices need to be cleaned frequently, and the sewage needs to be stirred during use. The stirring device setting further increases the difficulty of cleaning the reaction tank. The existing reaction tank inner wall is not cleaned thoroughly and has no stirring structure, which affects the processing efficiency and cannot meet the actual needs. Therefore, we have invented a synchronous sewage treatment and nitrogen and phosphorus recovery. bioelectrochemical device. Contents of the invention [0003] The inv...
