The utility model discloses a high-concentration organic
wastewater treatment device which comprises a tank body, the top end of the tank body is connected with a water inlet
pipe through a rotary water
distributor, and the interior of the tank body is divided into an electrolytic
catalytic oxidation area, an
anaerobic reaction area and a
sediment backflow area from top to bottom; the electrolytic
catalytic oxidation zone is provided with a plurality of
titanium-based
electrode plates which are arranged in parallel at intervals, a porous
ceramic catalyst is filled between the
titanium-based
electrode plates, the
anaerobic reaction zone is divided into a plurality of reaction chambers by a plurality of baffle plates, the adjacent baffle plates in the vertical direction deviate from each other, the bottoms of the baffle plates are provided with flow guide angles, and the flow guide angles are communicated with the reaction chambers. The
reaction chamber is filled with a modified
polyurethane biological filler; the
precipitation reflux zone comprises an inclined tube
precipitation layer and a conical
sludge hopper, and the conical
sludge hopper is connected with the head end of the
anaerobic reaction zone through a gas stripping
pipe. The high-concentration organic
wastewater treatment device has the advantages of being compact in structure, high in high-concentration organic
wastewater treatment efficiency and high in
impact resistance.
