[0002] The characteristics of high-concentration difficult-to-degrade organic wastewater are high concentration of organic pollutants and poor biodegradability. Pretreatment can be used to change the chemical structure of difficult-to-degrade organic matter, reduce its molecular weight, improve the biodegradability of wastewater, and effectively degrade organic pollutants in subsequent biological treatment processes. Fen ton oxidation method is one of the various catalytic pretreatment methods for high-concentration difficult-to-degrade organic wastewater. It has low investment cost, high tolerance to water quality variation, and easy operation and maintenance. For example, an oxidation device for a fluidized bed with application number 202120692703.0 includes a base, a fluidized bed oxidation tower and a connector. A fixed plate is fixedly installed on the middle section of the upper end of the base, and a triangular bracket is fixedly installed on the upper end of the fixed plate. The fluidized bed oxidation tower is fixedly installed in the triangular bracket, and a tower cover is fixedly installed on the top of the fluidized bed oxidation tower. A feed pipe is fixedly connected to the segment, a connector is fixedly installed on the top of the feed pipe, and the connector is communicated with the feed pipe, a gas storage box is fixedly installed on the upper end of the connector, and the gas storage box is communicated with the connector, a socket is opened on the right wall of the gas storage box, a through-hole plate is fixedly installed on the upper end of the interior of the gas storage box, an inner groove block is fixedly installed in the middle section of the inner cavity of the through-hole plate, and a polyethylene ball is movably installed in the inner groove block; the oxidation device for the fluidized bed has a simple structure and is easy to operate, and can effectively analyze and detect the gas in the wastewater as a whole, thereby improving the efficiency of wastewater treatment.

[0003] The above-mentioned fluidized bed oxidation device has the following defects during operation: (1) When the gas in the wastewater enters the gas storage box, negative pressure is easily generated during the wastewater transportation inside the tower body, causing suction effect in the pipeline. As a result, as the gas rises into the gas storage box, some debris will also enter the box and be transported to the detector through the pipeline, affecting the accuracy of the detector's gas analysis. For this reason, we propose a fluidized bed advanced oxidation device. Utility Model Content
