In this paper,the double demulsification process is used to realize high-efficiency separation of emulsion water and milk,and Fenton oxidation treatment is carried out on the wastewater generated by separation.Hydroxyl radical is generated by the chain reaction between bivalent iron ion and hydrogen peroxide,and organic matter in the wastewater is degraded with super oxidation capacity.By controlling the addition of 1.5%hydrogen peroxide and 4%ferrous sulfate in wastewater,the degradation rate of organic matter can be effectively improved,and the COD of wastewater water quality can be significantly reduced to less than 300mg/L,meeting the water intake target of the park sewage treatment plant.Increasing the reaction temperature can increase the reaction rate,but has little effect on reducing COD in wastewater.The process has the characteristics of simplicity,high efficiency and high conversion rate,and can be used as a technical reserve in hazardous waste treatment industry.
