The invention discloses an oily sewage treatment device and a treatment process. The device includes a regulating tank, an oil-water separation tank, a biological purification tank connected in sequence, and a control component for controlling the operation of the device. The regulating tank is provided with a primary filter for sewage Filtration components and flocculation components for flocculation and sedimentation of pollutants; oil-water separation components for promoting the decomposition of oily sewage are provided in the oil-water separation tank, and microbial decomposition components for using microorganisms to decompose and digest pollutants in sewage are provided in the biological purification tank; The sewage is filtered, flocculated and sedimented, oil-water separated and biodegraded, so that the oily substances in the sewage can be completely removed; the device of the invention has a reasonable structural design, high stability and reliability, and is suitable for mass promotion.
Description
technical field [0001] The invention relates to the technical field of oily sewage treatment, in particular to an oily sewage treatment device and a treatment process. Background technique [0002] The sources of oily sewage are very extensive, mainly from the following aspects: First, the largest part of the source is oil exploitation. A large amount of oily sewage will be produced in almost every link of oil exploitation. The second is the chemical and pharmaceutical industry. A large amount of water and lubricants are used in the treatment of chemical raw materials, the reaction process of raw materials and the separation process of products, which will cause a large amount of oily sewage in the pharmaceutical process. Furthermore, in the process of food processing and production, it is necessary to lubricate and frequently clean the equipment, and finally produce oily sewage. Oily wastewater has a very serious destructive effect on the ecosystem. If it cannot be treate...
