Description
Technical Field
The utility model belongs to the technical field of treatment of emulsified waste liquid and special waste water, and particularly relates to an advanced oxidation reaction treatment device for organic waste liquid.
Background
With the development of global economy and the acceleration of urbanization process, the discharge amount of industrial wastewater and domestic sewage is increasing day by day, and the pollution is very serious. Organic wastewater in which BOD >100mg/L, COD >2000mg/L is commonly referred to as high concentration organic waste liquor. These waste liquids generally have one or more hazardous properties of flammability, corrosivity, acute toxicity, leaching toxicity, reactivity, infectivity, carcinogenesis, teratogenicity, mutagenicity, and the like. Common methods for treating organic waste liquids include solvent extraction, membrane separation, oxidation, adsorption, and incineration. Wherein, the solvent extraction method, the membrane separation method, the oxidation method and the adsorption method are difficult to thoroughly eliminate the harm of organic waste liquid and are easy to cause secondary pollution. At present, developed countries abroad generally adopt incineration methods to treat waste liquid, although incineration equipment of high-concentration organic waste liquid is various, the waste liquid has high moisture content and low flammability, and suspended matters (namely emulsified waste liquid and the like) exist in the waste liquid, the waste liquid is not suitable for incineration method treatment, and the waste liquid widely exists in fine chemical industry, such as dimethyl sulfoxide (DMSO) is an aprotic polar solvent, is always called as a universal solvent due to the special solvent effect on chemical reaction and the dissolution property on a plurality of substances, is an important fine chemical raw material, and is used as a solvent in industries such as petroleum, chemical industry, medicine, electronics, synthetic fibers, plastics, printing and dyeing and the like, so that a plurality of purposes are developed; because the biodegradability of dimethyl sulfoxide (DMSO) wastewater is poor (BOD/COD is 0.02), a large amount of bulk volatile matter and secondary volatile matter (such as SO 2) are generated in the incineration process, which causes secondary pollution, and although the water content is high, the organic matter COD is also high, the odor is strong, and the degradability is poor, SO that the DMSO wastewater (especially high concentration) also becomes a difficult problem in the field of chemical waste liquid or special wastewater treatment.
Meanwhile, the automobile coating paint which is widely used at present is a typical high-COD emulsified waste liquid and is also a difficult problem in the field of chemical waste liquid or special waste water treatment. The advanced chemical oxidation method is a very effective method for decomposing refractory organic matters, and in recent 20 years, various advanced oxidation methods are discovered and rapidly applied to the field of water treatment, mainly comprising photocatalytic oxidation, sonochemical oxidation, electrochemical oxidation, wet oxidation, supercritical water oxidation and the like. The advanced chemical oxidation method enables the molecular kinetic energy of organic matters to reach the chemical reaction threshold, and particularly, wet oxidation is realized by means of increasing the temperature, so that the wet oxidation must be carried out under the harsh conditions of high temperature (125-.
