oil-polluted water The treatment involves dissolved oil, emulsified oil, dispersed oil, floating oil and other different forms of oil particles. The diameter of the oil slick is the largest, which can form a grease film under certain conditions. According to the characteristics of oil slick, people can use density difference and oil tank separation to separate oil and water. Dispersed oil is unstable to a certain extent, and will be converted into floating oil under static state, and also into dissolved oil under certain conditions.
Horizontal screw centrifuge The manufacturer suggests that the enterprise should analyze the actual characteristics of oily sewage according to its own production characteristics, select appropriate treatment technology, or make comprehensive use of multiple technologies. Gravity type and pressure type treatment technologies can reduce resource consumption, make oily sewage reach the treatment technical standard, improve the production process grade, make the production operation reach a more reasonable state, separate more crude oil, and make the water quality meet the requirements of standard water.
The concentration of oil in wastewater discharged by different industrial departments varies greatly. The oil content of wastewater generated during oil refining is about 150-1000mg/L, the tar content of coking wastewater is about 500-800mg/L, and the tar content of wastewater discharged from gas generating station can reach 2000-3000mg/L.
Therefore, Manufacturer of horizontal spiral centrifuge It is suggested that the oil separator should be used to recover the floating oil or heavy oil when treating oily wastewater. The treatment efficiency can reach 60% - 80%, and the oil content in the effluent is about 100-200mg/L. For emulsified oil and dispersed oil that are difficult to treat, attention should be paid to reducing the occurrence of emulsification. During the treatment process, the number of times of lifting wastewater with pumps should be minimized to reduce the degree of emulsification.
Common treatment methods include air flotation and demulsification.
