Oil-fume extraction and biological treatment method and device

Abstract

The invention relates to an oil-fume extraction and a biological treatment method and a device, particularly, the oil fume is led into an extraction unit and is washed through a detergent of a non-ionic surfactant; the oil fume is effectively emulsified to generate wastewater containing emulsified oil ; the emulsified oil of the wastewater is degraded to carbon dioxide and water solution by oil-decomposing bacteria, the degraded water solution is led into the extraction unit and mixed with the detergent to continue washing the oil fume; accordingly, a repeated circulatory system is formed, and the oil degradation rate can be maintained to be more than 99 percent.

Description

technical field [0001] The present invention is related to the oil fume treatment device, more specifically, especially emulsified oil that can effectively degrade waste water, and forms a repeated circulation system. Background technique [0002] Since human beings have entered the era of industrial technology, living standards have generally improved, and in order to allow the next generation to have a better quality of life, environmental awareness has gradually risen. [0003] Many catering operators in the market have to do cooking, frying, and even deep-frying every day. Oil products are prone to disturbing oil fume after high temperature or repeated use. There are at least 140,000 public nuisance complaints related to stench every year. More than 1,000 cases, 43% of which are related to the emission of lampblack from the catering industry. The air pollution and waste water produced by it have a considerable impact on the environment. Therefore, most businesses will in...

Problems solved by technology

[0003] Many catering operators in the market have to do cooking, frying, and even deep-frying every day. Oil products are prone to disturbing oil fume after high temperature or repeated use. There are at least 140,000 public nuisance complaints related to stench every year. More than 1,000 cases, 43% of which are related to the emission of lampblack from the catering industry. The air pollution and waste water produced by it have a considerable impact on the environment. Therefore, most businesses will install range hoods to directly extract the lampblack into the outdoor atmosphere. The air pollution in the surrounding environment is quite serious, and some operators direct the oil fume from the kitchen range hood directly into the sewer. Although it will not directly affect the air quality of the nearby environment, after a period of time, it will cause sewer pollution. The problem of oil pollution will not only cause the blockage of the sewer and affect the drainage function, but also cause the pollution of water resources, causing another environmental pollution problem
