[0002] COD, also known as chemical oxygen demand, is the amount of oxidant consumed when a certain strong oxidant is used to treat a water sample under certain conditions. Therefore, in the process of treating industrial wastewater, a reagent reaction device is needed to assist. For example, in the patent with the announcement number "CN218890562U" and the name "a reagent reaction device for petroleum treatment", a bottom plate is provided, a first support frame is welded and fixed on the top of the bottom plate, a reactor is fixed inside the first support frame by bolts, the bottom plate is convenient for improving the stability of the reactor when in use, and a feed pipe is embedded and fixed on the top of the reactor. However, the above structure still has the following problems in actual use:

[0003] The above structure adds reagents through the feed pipe during use. However, in the process of industrial wastewater treatment, adding the reagents at one time will slow down the fusion between the reagents and the industrial wastewater, thereby weakening the reaction effect. At the same time, it also requires longer stirring time to allow the reagents to be evenly fused, thereby affecting efficiency.

[0004] Therefore, we proposed an industrial wastewater treatment COD removal agent reaction device that can solve the above problems well. Utility Model Content
