description The invention discloses a sewage COD treatment device which comprises a bracket structure defined by a plurality of brackets, an inclined strut structure obliquely arranged in the bracket structure and a filter screen arranged on the inclined strut structure; the bracket structure is used for supporting the inclined strut structure; the inclined strut structure is used for supporting the filter screen; and the filter screen is used for filtering sewage and prolonging the retention time of the sewage so as to prolong the contact time of the sewage and air. According to the invention, the filterscreen is used for hanging and staying the sewage, filtering the sewage and prolonging the staying time of the sewage so as to prolong the contact time of the sewage and air, so that oxygen in the air is dissolved in water as much as possible to reduce the COD value, compressed air or blast air is not needed, a large amount of power consumption is saved, and the occurrence probability of faults is reduced; the service li
