Problems solved by technology
Because the cutting fluid needs to be replaced frequently, otherwise the processing effect of the workpiece is not good, and a large amount of cutting waste water will be generated
Because the content of oily substances in cutting fluid is large, oily substances are insoluble in water, and the density of oil is smaller than that of water, so if they are directly discharged into other water bodies without treatment, oily substances will float on the water surface, The air content in the water will be affected, leading to the death of animals and plants in the water
In the long run, the water body will deteriorate and produce foul smell, which will eventually lead to the pollution of the water body environment

A method for treating oily wastewater with energy-creating and energy-saving effects, comprising at least the following steps: providing oily wastewater with a first COD value; performing acidification and demulsification treatment on the oily wastewater, so that the oily wastewater is separated into an upper layer solution and a lower layer solution; The first coagulation and sedimentation treatment is performed on the lower layer solution to form sediment and the upper layer clear solution; and the contact aeration treatment step is performed on the upper layer clear solution with biological agents. The oily wastewater treatment method can obtain the influent solution with the second COD value meeting the influent standard.
Description
technical field [0001] The invention relates to a wastewater treatment method, in particular to an oily wastewater treatment method with energy-creating and energy-saving effects. Background technique [0002] The incidents of illegal discharge of oily wastewater in various countries in the world are increasing year by year, mainly due to the high technology and cost of oily wastewater treatment. In the process of cutting, forming and grinding of metals and their alloys, a kind of lubricating oil is usually used to cool and lubricate the cutting tools and workpieces. This liquid is called cutting fluid. Because the cutting fluid needs to be replaced frequently, otherwise the processing effect of the workpiece is not good, and a large amount of cutting waste water is generated. Because the content of oily substances in cutting fluid is large, oily substances are insoluble in water, and the density of oil is smaller than that of water, so if they are directly discharged into ...
