Embodiment 1

[0083] 1. Pass the waste emulsion to be treated through a fine mesh filter to filter it, wherein the filtration accuracy of the fine mesh filter is 90 μm; after filtering through the fine mesh filter, the waste emulsion with a particle size greater than 90 μm Oil slicks are removed.

[0084] 2. The waste emulsion that has removed the floating oil is introduced into the grease trap through the water distribution pipe, so that the waste emulsion flows through the oil-water separation pipe from bottom to top; after passing through the oil-water separation pipe, the dispersed oil and water in the waste emulsion have different specific gravity , the dispersed oil floats to the water surface to form oil-water separation, and the dispersed oil floating to the water surface is collected by the oil coalescing pipe; wherein, the angle between the oil-water separation pipe and the horizontal plane is 60°.

Abstract

The invention provides equipment for treating waste emulsion. The equipment is characterized by comprising a floating oil removal device, an oil-water separation device, and an electrochemical treatment device, wherein the floating oil removal device is used for removing floating oil from to-be-treated waste emulsion, and removing the floating oil floating on the level of the waste emulsion; the oil-water separation device is used for performing oil-water separation to the waste emulsion without floating oil, and removing the dispersion oil suspending in the waste emulsion; and the electrochemical treatment device is used for performing electrochemical treatment to the waste emulsion which is subjected to oil-water separation treatment, so that emulsifying oil and dissolved oil are flocculated, wherein an electrified aluminum plate and a nanoceramic membrane are used for performing electrochemical treatment; a disconnected nanoceramic membrane is used for performing ultrafiltration treatment to the stand and precipitated crude emulsion. After being treated through the equipment, the quality of effluent water is good, and the effluent water can completely meet the emission limit requirement of a public sewage treatment system in Beijing Integrated discharge standard of water pollutants DB11 / 307-2013.

Description

technical field [0001] The invention relates to industrial wastewater treatment equipment, in particular to equipment for treating waste emulsion, and belongs to the technical field of environmental protection. Background technique [0002] In the production process of machinery manufacturing and processing enterprises, a large amount of emulsion is used for lubrication and cooling in metal cutting. After a period of use, the emulsion will become waste water and be discharged. This kind of waste emulsion mainly contains organic oil and surfactant, which is prepared by diluting emulsified oil with water as needed and then adding emulsifier. At the same time, due to the dissolution of a large number of metal particles during the metal cutting process. Therefore, this kind of waste emulsion wastewater also contains a large amount of metal particle pollutants. [0003] Due to the high oil content of the waste emulsion, the concentration of organic pollutants in it is very high...
