Production Factory of Oily Wastewater Treatment Equipment

Oil substances contained in oily wastewater, including natural petroleum, petroleum products, tar and its fractionates, and edible animal and vegetable oils and fats. From the pollution of water, mainly oil and tar. Because the concentration of oil in the wastewater discharged from different industrial sectors varies greatly, such as the wastewater produced in the refining process, the oil content is about 150 to 1000mg/L, the tar content in the coking wastewater is about 500 to 800mg/L, and the tar content in the wastewater discharged from the gas generating station can reach 2000 to 3000mg/L. Therefore, the treatment of oily wastewater should first use the grease trap, recover the oil slick or heavy oil, the treatment efficiency is 60%-80%, the oil content in the output water is about 100-200mg /L; Emulsified oil and dispersed oil in wastewater are difficult to treat, so emulsification should be prevented or reduced

    Product function

    Oil substances contained in oily wastewater, including natural petroleum, petroleum products, tar and its fractionates, and edible animal and vegetable oils and fats. From the pollution of water, mainly oil and tar. Because the concentration of oil in the wastewater discharged from different industrial sectors varies greatly, such as the wastewater produced in the refining process, the oil content is about 150 to 1000mg/L, the tar content in the coking wastewater is about 500 to 800mg/L, and the tar content in the wastewater discharged from the gas generating station can reach 2000 to 3000mg/L. Therefore, the treatment of oily wastewater should first use the grease trap, recover the oil slick or heavy oil, the treatment efficiency is 60%-80%, the oil content in the output water is about 100-200mg /L; Emulsified oil and dispersed oil in wastewater are difficult to treat, so emulsification should be prevented or reduced
    Process flow: The treatment process of oily wastewater is generally the initial oil-water separation (such as the use of oil separator), and then the second step of oil-water oily wastewater treatment facilities (floating or coagulation). This process can not only prevent the treatment unit from being blocked by oil products, but also better play the oil removal performance of each unit. The degree of emulsification can be reduced by removing oil once in the process before lifting with the pump.

    Main use

    Oily wastewater will be wasted if it is not recovered and treated. When discharged into rivers, lakes or bays, it will pollute the water body and affect the survival of aquatic organisms. Used for agricultural irrigation, it can block soil gaps and hinder crop growth.
    Application: Oily wastewater is mainly used in petroleum, petrochemical, iron and steel, coking, gas generating station, mechanical processing and other industrial sectors. In addition to heavy tar, the relative density of oil pollutants in wastewater is more than 1.1, the rest of the relative density is less than 1.
