Abstract

The invention discloses an efficient aerated plasma treatment organic wastewater device which comprises a high-voltage electrode, a grounding electrode and a reaction vessel. The high-voltage electrode and the grounding electrode are connected with a positive electrode and a negative electrode of a plasma power supply, a microporous aeration pipe is arranged in the reaction vessel in a sleeving manner, an annular water channel is formed between the wall of the reaction vessel and the microporous aeration pipe, an inner medium pipe with a closed lower end is arranged in the microporous aeration pipe in a sleeving manner, the high-voltage electrode is embedded into the inner medium pipe, the grounding electrode is arranged in a closed discharging area formed between the microporous aeration pipe and the inner medium pipe in the annular water channel, a water inlet pipe and a backflow water outlet pipe are arranged on the upper portion and the lower portion of the annular water channel, and an air outlet and an air inlet are formed in the top and the bottom of the discharging area. According to the device, ozone generated by discharging plasmas is sufficiently utilized, and the device has a good application prospect and has the advantages of stable and high performance, no secondary pollution, rapidness, simple structure, high practicability and the like in the field of water treatment.

Description

technical field [0001] The invention relates to a sewage treatment device in the field of environmental protection, belongs to the application technical field of low-temperature plasma, and specifically relates to a high-efficiency aeration type plasma treatment device for organic waste water. Background technique [0002] With the rapid development of the economy and the acceleration of urbanization, the increasingly serious water pollution problem in our country has become increasingly prominent, making the situation of water shortage we are facing more severe. Therefore, efficient wastewater treatment technologies are required to alleviate this problem. [0003] Plasma sewage treatment device is a new device for domestic sewage treatment and disinfection technology. Through high-energy plasma shocking water body, a large number of strong oxidizing particles, such as hydroxyl radicals, can be generated in the water body, which can degrade organic matter in water. Oxidatio...
