A floating oil recovery treatment device

technical field

The utility model relates to a floating oil recovery and treatment device, in particular to recovery of waste oil floating on the surface of an underground sewage pool, and belongs to the technical field of floating oil recovery and treatment.

Background technique

A certain amount of oil is often mixed in industrial wastewater such as refining, chemical, and metallurgy. At the same time, with the development of economy and the improvement of people's living standards, oily substances such as animal and vegetable oils and mineral oils in urban sewage are gradually increasing. At present, there are mainly three types of research methods on oily sewage treatment at home and abroad: chemical treatment, physical treatment and biochemical treatment. In the practical application technology of oil-water collection and separation, cyclone and gravity separation technologies are traditionally used to collect and separate oil. At present, oil slick collectors are commonly used to recover oil slicks. The usual measures are: use hoses or float oil collectors (such as Chinese patent application No. 201310291934.0) to float at the interface of oil and water, and when there is a lot of oil, pump out the oil . Background technology Although there is a certain recovery effect, it must be ensured that a certain amount of oil pollution can be used to play a good role; and due to large changes in water volume and water quality, the position of the hose or the oil collector is deviated, and it cannot be recovered. Normal processing, low oil collection efficiency, the oil well pump and motor of the recovery equipment described in Chinese Patent Application No. 201310291934.0 are all installed on the float plane, which is inconvenient for equipment maintenance, and the oil collection port is easy to block and difficult to clean.
