Although this method has strong adaptability to water quality and stable water output effect, the equipment cost and daily operation cost required by this method are relatively high.
[0006] The existing separation methods for volatile organic compounds in wastewater generally have disadvantages such as high treatment costs, high requirements for influent water quality, and strong toxicity of intermediate products.

Abstract
The invention provides a device and a method for separating volatile organic matter in waste water. The device and method are used according to a principle that the solubility of volatile organic matter with a low boiling point in water is greatly reduced with the increase of the vacuum degree and the temperature, so that the organic matter can be separated from the waste water. The device comprises a front end socket, a two-flow water chamber, a front tube plate, a shell, a spray tube, a heat exchange tube bundle, a back tube plate, a one-flow rear water chamber and a rear end socket. Negative-pressure steam is condensed and releases latent heat in heat exchange tubes; waste water is sprayed by the spray tube to form a thin and uniform liquid film on the outer wall of the heat exchange tube bundle for carrying out organic matter separation and preheating, and separated gas organic matter is pumped out by an air extraction device. According to the invention, preheating of the waste water is completed while the separation of 89% or more of volatile organic matter with a low boiling pint is realized, and the industrial waste water forms the thin and uniform liquid film on outer wallof the heat exchange tube bundle, so that the contact area between the waste water and the gas phase is increased, and the separation efficiency of the volatile organic matter is improved.
Description
technical field [0001] The invention belongs to the field of industrial wastewater treatment, and in particular relates to a separation device and method for volatile organic compounds in industrial wastewater. Background technique [0002] With the rapid development of my country's industry, the discharge of industrial wastewater has increased significantly year by year. Industrial wastewater contains a large amount of volatile organic compounds, the most representative of which are benzene organic compounds and phenolic organic compounds. These organic compounds are highly toxic and pollute a wide range. The direct discharge of industrial wastewater without treatment will cause serious pollution to the environment and even endanger the health of animals and humans. To this end, my country has promulgated relevant laws: "Law of the People's Republic of China on the Prevention and Control of Air Pollution", which requires the treatment or recycling of volatile organic compo...
