Abstract

The invention discloses a waste emulsion resource utilization treatment system. The waste emulsion resource utilization treatment system comprises an emulsion collection tank, a filtering unit, a first acid storage tank, an oil separation device, an ultrafiltration device, a second acid storage tank, a demulsification tank, a DTRO unit, a floating oil collection tank, a rectification device, a concentrated liquid collection tank, an evaporation device and a biochemical treatment unit. The invention also discloses a waste emulsion resource utilization treatment process. A purpose of recycling mineral oil extracted from waste emulsion is achieved, and meanwhile, the waste liquid is stably treated to reach the standard.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a waste emulsion resource utilization treatment system and process. Background technique [0002] In machining, metal rolling and other industries, cutting and grinding machine parts, metal rolling and other processing processes, emulsion is widely used as a medium for cooling, lubricating or transmitting pressure. After the emulsion is recycled for many times, it will become rancid and deteriorate to varying degrees, and its performance will be reduced. It needs to be replaced to form a waste emulsion. In addition to the hazards of general oily wastewater, waste emulsions are highly dispersed in water due to the action of surfactants, which are more easily absorbed by animals, plants, and aquatic organisms, and surfactants themselves are harmful to organisms, and can also dissolve some water-insoluble of toxic substances. The higher the degree of emulsification of...
