Background
The oily wastewater comes from industries such as petroleum, mechanical processing, ship transportation, food processing and the like, and the oils generally comprise petroleum, petroleum products, animal and vegetable oils and fats. Oils are generally present in wastewater in three states: oil substances are generally present in the waste water in four states.
(1) Free oil with oil drop particle size larger than 15 μm and easy to separate in water
(2) Dispersing oil, oil drop with particle size of 1-15 μm, suspending in water
(3) The emulsified oil has oil drops with the particle size less than 1 mu m, and the oil product has small dispersed particle size in the wastewater, is in an emulsified state and is not easy to separate from the wastewater.
(4) Dissolving oils, oils dissolved in water
At present, the air floatation treatment mode of the oily wastewater is distinguished from the aspect of gas production mechanism, and generally, the air floatation method is a dissolved air floatation method, a mechanical cavitation air floatation method and an electrolytic air floatation method. The former two are commonly used, and the diameter of the generated bubbles is generally 20-40 μm; the diameter of the bubbles generated by the improved air flotation modes such as shallow air flotation, rotational flow air flotation and the like can reach 15 mu m, and the improved air flotation device can achieve good effects on free oil and dispersed oil.
The electrolytic air floatation is to generate a large amount of tiny bubbles of hydrogen and oxygen on a reaction polar plate under the action of direct current, the diameter of the bubbles can even reach 1 mu m, and the electrolytic air floatation has excellent removal effect on oil substances in the oily wastewater. However, because the conventional electrolytic air flotation reactor is generally an immersed open-type reactor, pollutants in the wastewater can have irreversible influence on the polar plate in the treatment process, so that the problems of reduced air flotation efficiency, reduced service life of the polar plate, high operation energy consumption and the like frequently exist, and the development of the electrolytic air flotation technology is hindered.
