Concentrated water catalytic oxidation device

The utility model provides a concentrated water catalytic oxidation device. The device comprises an ozone generator, an ozone plate type heat exchanger, a catalytic oxidation tower and pipelines of various models, the ozone generator is provided with four interfaces; the four interfaces are respectively a gas interface, a water outlet interface, a water inlet interface and a catalytic oxidation tower interface; the ozone plate heat exchanger is connected to incoming circulating water through a pipeline; and the catalytic oxidation tower is connected with incoming water of the biochemical water producing pool through a pipeline. According to the device, wastewater enters the catalytic ozonation tower and flows back through the effluent circulating pump of the catalytic ozonation tower, so that the treatment efficiency is improved, meanwhile, the catalytic tower is filled with a catalyst, and ozone generated by the ozone generator is introduced. The wastewater reacts with ozone under the action of the catalyst
