Problems solved by technology

[0003] The COD of aquaculture sewage is mainly caused by the organic matter in the wastewater. Therefore, the main function of the COD removal agent is to effectively remove the organic matter in the sewage. Usually, the COD remover is directly added to the discharge port to make the COD remover and the sewage. COD reaction, thereby reducing or even removing the COD concentration, but the COD removal agent in the existing sewage treatment equipment reacts with the COD in the wastewater for too long, and the COD removal agent is not evenly discharged into the wastewater, resulting in low sewage treatment efficiency , and reduce the utilization rate of COD remover

Abstract

The invention relates to equipment for efficiently removing COD in breeding wastewater, belonging to the technical field of aquaculture wastewater treatment. The equipment comprises a tank body, wherein the top of the tank body is connected with a feeding hole; the feeding hole is arranged to be hopper-shaped; the top of the tank body is connected with a supporting seat; the top of the supportingseat is connected with a motor; the output end of the motor is connected with a spindle; the end, away from the motor, of the spindle penetrates through the supporting seat and is connected with a rotating shaft; two first fixed rings are connected to the outer wall of the rotating shaft; an outer frame is arranged between and connected with the two first fixed rings; outer stirring blades are connected to the outer wall of the outer frame; a first bevel gear is connected to the outer wall of the rotating shaft; and a sealing box is connected to the outer wall of the rotating shaft through a first bearing. According to the invention, the outer stirring blades and inner stirring blades are matched with each other and are opposite in rotating direction, so the reaction rate of a COD removerand COD in sewage is increased, sewage treatment efficiency is improved, and the utilization rate of the COD remover is increased.

Description

technical field [0001] The invention relates to the technical field of aquaculture wastewater treatment, in particular to a device for efficiently removing COD in aquaculture wastewater. Background technique [0002] COD is a chemical method to measure the amount of reducing substances that need to be oxidized in water samples, and the oxygen equivalent of substances (generally organic substances) that can be oxidized by strong oxidants in wastewater, wastewater treatment plant effluent and polluted water , in the study of river pollution and industrial wastewater properties and the operation and management of wastewater treatment plants, it is an important and quickly measured organic pollution parameter, often expressed by the symbol COD. [0003] The COD of aquaculture sewage is mainly caused by the organic matter in the wastewater. Therefore, the main function of the COD removal agent is to effectively remove the organic matter in the sewage. Usually, the COD remover is ...
