Wastewater treatment equipment for aquaculture seawater

Abstract

The invention discloses wastewater treatment equipment for aquaculture seawater, relates to the technical field of wastewater treatment equipment, and includes an impurity filtering mechanism, a filtering box, a controller, a multi-stage processing mechanism, and a detection backflow mechanism. The multi-stage processing mechanism includes: The algae polyculture tank, the mixing component, the sterilization component and the bacteria treatment cylinder, the impurity filter mechanism includes two multi-stage filter components, the position conversion component and the filter mesh dredging component, the position conversion component includes the installation horizontal plate, Height adjustment part and swivel part. The present invention can realize the continuous automatic treatment of aquaculture wastewater, and can realize the replacement of the filter screen adhering impurities under the action of the impurity filtering mechanism, and can dredge the mesh holes of the adhering impurity filter screen, when the bacteria content and When the nitrogen and phosphorus content does not reach the standard, the second water pump can retransmit the sewage that has not reached the standard to the filter box to realize the secondary purification of the sewage.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment equipment, in particular to wastewater treatment equipment for aquaculture seawater. Background technique [0002] In recent years, my country's marine aquaculture industry has developed rapidly, and the area and scale of aquaculture are increasing. At the same time, there are also some problems in the breeding process. Because my country's mariculture mostly adopts high-density farming methods, a lot of bait is put in, the water body has a high bearing capacity, and the frequency of water changes is high. The pollution of aquaculture water leads to an increase in the concentration of ammonia nitrogen, nitrite, nitrate, COD, and organic matter. At the same time, it is easy to breed bacteria, causing deterioration of the water body, and causing toxicity to aquaculture organisms. Wastewater containing pollutants is discharged into the surrounding natural water bodies, which will cause w...
