Aquaculture wastewater circulating treatment equipment

Abstract

The invention discloses aquaculture wastewater circulation treatment equipment, which relates to the technical field of wastewater treatment, and comprises a box body and a plurality of MBR membrane groups mounted in the box body, and further comprises a wastewater trend control mechanism, the sewage guide device comprises two folding plates arranged on one side of an MBR membrane group, a sewage guide channel mounted between the two folding plates and a lifting assembly for driving the sewage guide channel to lift; the closed membrane cleaning mechanism comprises a structural groove formed in the top of the sewage guide channel, a sealing plate mounted in the structural groove and a linkage assembly used for driving the sealing plate to rotate; by changing the flowing height of the sewage guide channel, wastewater can uniformly enter each height position of the MBR membrane group, so that the uniformity of impurity accumulation at each position of the MBR membrane group is improved, the problem of large difference of impurity accumulation at each position of the MBR membrane group is solved, the cleaning period of the MBR membrane group is prolonged, the MBR membrane groups are separated and then subjected to reverse flushing, and the cleaning efficiency of the MBR membrane group is improved. And the problem of mutual influence during cleaning of the MBR membrane groups is avoided.
