Domestic sewage primary sedimentation tank deodorization device

The invention relates to the technical field of sewage treatment, in particular to a domestic sewage primary sedimentation tank deodorization device which comprises a flow injection pipe, a control box is fixedly connected to one end of the flow injection pipe, a control barrel and discharge plate boxes are arranged in the control box, a plurality of discharge plate boxes which are evenly distributed are fixedly arranged around the control barrel in a surrounding mode, and the flow injection pipe is sleeved with the control barrel, a control column is arranged in the middle of the control barrel; a plurality of supporting plates are uniformly and fixedly arranged between the control column and the control barrel in an annular manner. By means of the structural design, in the process that a liquid deodorization agent is injected into the primary sedimentation tank, the control barrel drives the discharge plate box to rotate, then the effect of stirring sewage in the primary sedimentation tank is achieved, the
