Wastewater treatment equipment for aquaculture seawater

Abstract

The invention discloses wastewater treatment equipment for aquaculture seawater. The invention relates to the technical field of wastewater treatment equipment. The equipment comprises an impurity filtering mechanism, a filtering box, a controller, a multi-stage treatment mechanism and a detection backflow mechanism, wherein the multi-stage treatment mechanism comprises an algae polyculture pond,a material mixing assembly, a sterilization assembly and a bacterium treatment cylinder, the impurity filtering mechanism comprises two multi-stage filtering parts, a position conversion assembly anda filter screen mesh dredging assembly, and the position conversion assembly comprises a mounting transverse plate, a height adjusting part and a rotating part. According to the invention, continuousautomatic treatment of aquaculture wastewater can be realized, under the action of the impurity filtering mechanism, a filter screen adhered with impurities can be replaced, meshes of the filter screen adhered with impurities can be dredged, and when the bacterium content and the nitrogen and phosphorus content do not reach the standard, a second water pump can convey sewage which does not reach the standard into the filtering box again, so that secondary purification operation on the sewage is realized.

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...
