The present invention relates to the field of
wastewater treatment, and in particular to a
hydrogen peroxide wastewater treatment device combining
aeration and
sludge, comprising a tank body, wherein a stirring mechanism is arranged in the tank body, wherein the stirring mechanism comprises a rotating shaft, and a lower stirring rod and an upper stirring rod arranged parallel to each other along the axial direction thereof, and a counter-
aeration component is arranged between the lower stirring rod and the upper stirring rod, wherein the counter-
aeration component comprises upper aeration nozzles distributed at equal intervals along the axial direction of the lower stirring rod, and lower aeration nozzles distributed at equal intervals along the axial direction of the upper stirring rod, and an anti-blocking structure is arranged between the upper aeration
nozzle and the lower aeration
nozzle. The present invention ensures uniform mixing of
wastewater and
sludge through synchronous movement of the upper stirring rod and the lower stirring rod, and simultaneously utilizes the lower aeration
nozzle and the upper aeration nozzle to inject
oxygen-rich gas into the
water body, thereby facilitating contact between
suspended solids and bubbles and reducing accumulation of
solid particles in the aeration gap.
