A contact oxidation reactor

Abstract

An embodiment of the present invention provides a contact oxidation reactor. The end of the side wall of the reactor body of the reactor is provided with a water inlet, a water outlet, and a first sewage outlet for discharging sediment, which is higher than the water inlet. The first preset distance is lower than the second preset distance of the water outlet, the filter layer is laterally sealed and laid in the reactor body, the agitator penetrates the top of the reactor body and the filter layer is placed in the reactor body, and is connected with the drive. The device is connected; the first valve port of the three-way valve is connected with the water outlet, the second valve port is connected with the external pipeline for drainage, the third valve port is connected with the circulating pipeline through the circulating pump, and the end of the circulating pipeline where the nozzle is installed is placed In the reactor body, the other end is connected with the third valve port. Therefore, the reactor provided by the embodiment of the present invention can be applied to the cleaning of rural domestic sewage.

Description

technical field [0001] The invention relates to the technical field of wastewater biological contact oxidation reaction, in particular to a contact oxidation reactor. Background technique [0002] Because the current rural domestic sewage has the characteristics of high ammonia nitrogen and high total nitrogen, and the carbon-nitrogen ratio is greater than 3:1, and the carbon-nitrogen ratio is out of balance. Therefore, the current rural domestic sewage has become a major pollution source of nitrogen, phosphorus and other nutrients. Not only does it make it difficult for the total nitrogen to be discharged up to the standard, but it is also easy to produce foam overflow during the wastewater treatment process to pollute the environment, and also affect the appearance. [0003] At present, in the wastewater treatment process, technical means such as anaerobic ammonium oxidation, nitrification and denitrification, and short-cut nitrification and denitrification are usually use...

Problems solved by technology

[0002] Because the current rural domestic sewage has the characteristics of high ammonia nitrogen and high total nitrogen, and the carbon-nitrogen ratio is greater than 3:1, and the carbon-nitrogen ratio is out of balance. Therefore, the current rural domestic sewage has become a major pollution source of nitrogen, phosphorus and other nutrients. Not only does it make it difficult for the total nitrogen to be discharged stably, but also it is easy to produce foam overflowing and pollute the environment during the wastewater treatment process, which also affects the appearance

[0003] At present, in the wastewater treatment process, technical means such as anaerobic ammonium oxidation, nitrification and denitrification, and short-cut nitrification and denitrification are usually used to remove total nitrogen in wastewater, which can effectively solve the problem of total nitrogen pollution in wastewater. Complex problems such as large infrastructure investment, large land occupation, long cycle, and cumbersome actual control process are difficult to apply to the characteristics of rural domestic sewage such as small treatment volume, scattered distribution, and difficulty in concentrating on large-scale infrastructure facilities.
