Source analysis of oily sewage<\/p>\n\n\n\n<p>The sources of oily sewage are very extensive. Oily sewage is\ngenerated in the processes of steel refining, industrial production, oil\nextraction, pesticide and food processing and production, and these oily\npollutants mainly exist in four forms, respectively It is dissolved oil,\ndispersed oil, slick oil and emulsified oil.<\/p>\n\n\n\n<p>Petrochemical industry. In the petrochemical industry, oily\nwastewater will be generated at almost any stage from the initial extraction to\nthe final transportation and consumption. With the rapid development of China&#8217;s\nscience and technology, China&#8217;s tertiary oil recovery technology has also been\nwidely used. Improved the oil displacement effect, but also made the\ncomposition of sewage more complicated.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"http:\/\/oilfield.gnsolidscontrol.com\/wp-content\/uploads\/2019\/12\/2019110607511.jpg\" alt=\"\" class=\"wp-image-3558\"\/><\/figure>\n\n\n\n<p>Chemical and pharmaceutical engineering. The main source is oily\nwastewater from high-concentration processes. During the manufacturing process,\na large amount of water and lubricating oil are used in the stages of raw\nmaterial reaction, product separation and raw material pretreatment, so a large\namount of oily wastewater will be produced in the later stage.<\/p>\n\n\n\n<p>Metal smelting industry. In the process of metal smelting, whether\nit is the material in contact with oil or the equipment in contact with oil, we\nneed to cool, clean and lubricate it, and the lubricating oil may directly\ncontact with it, so it will form oily sewage .<\/p>\n\n\n\n<p>Food processing and production. In the process of food processing\nand production in our country, oily sewage is generated during equipment\ncleaning and machine lubrication.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"http:\/\/oilfield.gnsolidscontrol.com\/wp-content\/uploads\/2020\/05\/20200410_Oil_Sludge_Treating_System.jpg\" alt=\"\" class=\"wp-image-3651\"\/><\/figure>\n\n\n\n<p>GN Solids Control is one of the few manufacturing companies with\nexperience in oily sludge treatment plants at home and abroad. Our processing\nequipment has passed the verification of many practical applications on site\nand has been widely recognized by customers. It can meet the treatment of most\noily sludge, better recover oil and water, and reduce the cost of solid waste\ntreatment.<\/p>\n\n\n\n<p>Oily sludge refers to a mixture of oil, water and solids. In order to treat sludge and recover oil and water, oil, water and solids must be separated. At the same time, how to dispose of solids at a lower cost and recover as much oil as possible is very important. GN Solids Control oily sludge treatment complete equipment, including <a href=\"https:\/\/gnsolidscontrol.com\/decanting-centrifuge\">centrifuge<\/a>, <a href=\"https:\/\/gnsolidscontrol.com\/shale-shaker\">shale shaker<\/a>, <a href=\"https:\/\/gnsolidscontrol.com\/dewatering-unit\">chemical dosing unit<\/a>, through chemical hot washing, and then through multi-stage separation, and finally obtain clean oil and water, and low oil content solids. The recovered oil can be sold to refineries, and the water can be repeatedly hot washed. The oil content of the separated solid phase material can be as low as 2%, and finally it can be pyrolysis or biodegradation to achieve harmless treatment requirements.<\/p>\n\n\n\n<p>More question, welcome contact <a href=\"https:\/\/gnsolidscontrol.com\">GN Solids Control<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>1.
