The invention discloses a swirling flow-gas flotation oil-water separation system based on discharge plasma. The system comprises a sedimentation tank, a water suction pump, a filter, an overflow valve, a flow sensor, a pressure sensor, an electric valve, a water tank, a self-excited oscillation jet nozzle, a cyclone, a dross barrel, a sampling valve, an industrial oxygen generator, an SED plasmageneration device, a power supply and an industrial personal computer. A wastewater pretreatment technology, hydrocyclone, air flotation and atmospheric pressure ionization are combined to treat oilywastewater; the defects of a traditional treatment method and a single treatment method are overcome, a large number of free radicals with strong oxidizing property are generated in the reaction process, almost all organic matters can be oxidized until the organic matters are completely decomposed, the reaction conditions are mild, and a series of chain reactions can be induced; the method disclosed by the invention can be combined with other water treatment technologies to be used as pretreatment or advanced treatment of other treatment technologies, and has quite important theoretical significance and wide application prospect.
Description
technical field [0001] The invention relates to the technical field of oily wastewater treatment, a system for treating oily wastewater by combining wastewater pretreatment, hydrocyclone, air flotation and atmospheric pressure ionization, in particular a discharge plasma-based cyclone-air flotation oil-water separation system. Background technique [0002] With the urbanization of the country and the rapid development of society, the amount of industrial, agricultural and domestic water and sewage has increased greatly, but the relative lag of wastewater treatment facilities has caused a large amount of wastewater to be discharged directly without treatment, resulting in the surrounding environment and environment. Human life is under great threat. In the field of oily wastewater treatment, oily substances mostly exist in the form of emulsified oil, dispersed oil, and adsorbed oil in wastewater. In this form, the oil is suspended and finely divided, making it difficult to r...
