Abstract

The invention discloses a reactor for wet oxidation treatment of wastewater. The reactor comprises a reactor shell, a water inlet pipe arranged at the lower part of the reaction shell, an aerating apparatus, a fixing device for fixing a catalyst, a scrapping device for cleaning the surface of the catalyst, and a collecting device, wherein the scrapping device comprises a scrapping component jointed with the surface of the catalyst, and a driving mechanism for driving the catalyst to rotate. According to the reactor for the wet oxidation treatment of the wastewater, the catalyst can be driven to rotate by means of the driving mechanism, the scrapping component, jointed with the surface of the catalyst, can remove the contaminants, adhered to the surface of the catalyst, in the rotating process of the catalyst, so that the catalyst can be in full contact with sewage, the catalytic effect of the catalyst is maximized, and the efficient treatment of the sewage is guaranteed.

Description

technical field

[0001] The invention belongs to the technical field of wastewater treatment, in particular to a reactor for wet oxidation treatment of wastewater. Background technique

[0002] Wet oxidation is a process method for efficiently treating toxic, harmful, high-concentration and refractory organic wastewater. The principle of this process is to use oxygen or air (ozone or hydrogen peroxide) as an oxidant under high temperature and high pressure conditions. Realize the oxidative decomposition of pollutants in wastewater. This technology can treat toxic and harmful wastewater with a COD concentration of tens of thousands or even hundreds of thousands. At the same time, the removal efficiency of pollutants is high, which can significantly improve the biodegradability of wastewater. Due to the great technical advantages of wet oxidation technology, it has broad application prospects in chemical wastewater and sludge treatment. In order to ensure the oxidation treat...

Embodiment Construction

[0017] Such as Figure 1-4 As shown, a reactor for wet oxidation treatment of wastewater includes a reactor shell 1, a water inlet pipe 11, an aeration device, a fixing device, a scraping device and a collection device. The reactor shell 1 is a metal cylinder, and its The upper end is open, and the lower end is connected with a sewage discharge pipe 12, and a valve is arranged inside the sewage discharge pipe 12, which is used to discharge the residue in the sewage. Sewage is discharged into the interior of the reactor shell.

[0018] The aeration device includes an aeration pan 2, a nozzle 21, an air pipe 22 and an air supply member. The aeration pan 2 is fixed on the inner wall of the reactor shell 1, and the aeration pan 2 is provided with a plurality of through grooves. It is used for the passage of residue, and an aeration chamber is opened inside the aeration disc 2 for the passage of gas. The air supply part can be a conventional air pump, which is used to transport ox...
