Abstract

The invention discloses a water curtain type discharge plasma efficient treatment device for organic wastewater. The treatment device comprises a high voltage electrode and a grounding electrode which are respectively connected with the positive and negative electrodes of the plasma power source, and an outer medium tube and an inner medium tube which are sleeved together, between the outer medium tube and the inner medium tube is a water curtain discharge area; wherein the outer wall of the outer medium tube is provided with an annular overflow groove, the outer groove wall of the annular overflow groove is higher than the tube wall of the outer medium tube, the grounding electrode is arranged in the annular overflow groove, the high-voltage electrode is embedded in the inner medium tube, the lower end of the inner medium tube is sealed, the lower end of the outer medium tube is communicated with a lower water tank, and the upper end of the annular overflow groove is sealed and provided with an air inlet pipe. The device takes full advantage of the ozone generated by the discharge plasma. In the field of water treatment, the device has the advantages of stable and high performance, no secondary pollution, high speed, simple structure, strong practicability and the like, and has a relatively good application prospect.

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 in particular relates to a water curtain type discharge plasma efficient organic wastewater treatment device. 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. Oxi...
