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.
