Problems solved by technology

[0004] There is a bottleneck in the treatment of machining waste cutting fluid in China. Many combined treatment processes can successfully reduce its COD to thousands of mg / L, but it is very difficult to further improve the treatment efficiency and comprehensively utilize it.
In my country, the high-concentration and severely emulsified waste cutting fluid discharged from machining has not been well treated and reused.

Abstract

A method for producing organic fuel and distilled water from waste cutting fluid, comprising the following steps: using a metal filter screen to filter and remove metal mechanical impurities in the waste liquid; The body is successfully separated from the water, and then the water in the system is gradually distilled out by means of atmospheric distillation. Finally, when the water content of the remaining organic matter is 10-15%, add an emulsifier and stir to form a microemulsion-type environmentally friendly fuel. The process is convenient, the equipment is simple, the cost is low, and the effect is good, which effectively reduces the cost of waste cutting fluid treatment, and realizes the resource utilization of waste cutting fluid, turning waste into treasure.

Description

technical field [0001] The invention belongs to the technical field of hazardous waste treatment, and in particular relates to a method for producing environment-friendly organic microemulsion fuel and distilled water by using waste cutting fluid. Background technique [0002] Cutting fluid is a lubricating and cooling fluid used in metal processing and manufacturing. It will fail and be scrapped after its performance decreases. Waste cutting fluid is a hazardous waste with high COD concentration, large chroma, complex composition and extremely difficult biochemical treatment. Waste cutting fluid contains a large amount of organic pollutants, which are difficult to biodegrade, and direct discharge will cause serious environmental pollution. [0003] With the rapid development of the equipment manufacturing industry, the discharge of this oily hazardous waste is increasing day by day. The waste cutting fluid after use mainly contains four components: the first is water, and...
