Problems solved by technology

Because this method produces air pollutants during the combustion process, it not only consumes a lot of energy, but also the waste gas produced by the combustion method is difficult to meet the emission standards
(2) Chemical treatment: This method has limited treatment effect and uses a large amount of chemical reagents. While the COD of sewage is reduced, the salt concentration is greatly increased, and the cost is very high.

Abstract

The invention discloses a novel waste emulsion treatment process. Innocent treatment of waste emulsions can be achieved through the process flows of demulsification and micro-nano air flotation deoiling, MVR evaporation treatment, ozone micro-nano bubble catalyzed oxidation, nano-ferrum mediated ultrasonic catalyzed oxidation, efficient biochemical treatment and deep purified recycling / emission, the treated waste emulsions can be directly discharged or recycled, the treatment effect is efficient and rapid, and the COD removal rate is high; and the process does not have selectivity and can be extensively applicable to treatment on all classes of waste emulsions.

Description

Technical field: [0001] The invention relates to the technical field of wastewater treatment, in particular to a novel waste emulsion treatment process. Background technique: [0002] For a long time, my country has been facing the dual pressure of water shortage and water pollution. Industrial wastewater is the main source of water pollution. Among them, emulsion wastewater mainly comes from steel cold rolling industry, automobile industry, mechanical processing industry, petrochemical industry, printing and dyeing, Food processing and other industries are widely distributed, ranking first among all kinds of industrial wastewater. [0003] Because it contains an emulsifier, it belongs to the oil-in-water emulsification system. Its main components are machine oil or mineral oil, soap, emulsifier, defoamer, lubricating preservative, soluble organic matter, metal cuttings and solid suspended matter. It also contains A certain concentration of surfactant, stabilizer, emulsified...
