Description

An oil-water separation device for wastewater treatment in gas stations

technical field

The invention relates to the technical field of oil-water separation devices, in particular to an oil-water separation device applied to the treatment of waste water in gas stations.

Background technique

Gas station refers to the place where motor vehicles add fuel. The fuel of motor vehicles is mainly gasoline and engine oil. Gas station cleaning and daily life also produce a lot of waste water, but the waste water here is different from the waste water in other places. , is a mixture of gasoline or engine oil and water. During the discharge of this oil-water mixture, the oil and water must be separated, otherwise it will cause damage to the environment.

"An oil-water separation device for treating oily wastewater" disclosed in the publication number "CN101602528A", the invention includes a sewage filter tank and an oil-water separation host, the sewage filter tank is provided with a filter basket, a filter screen and a sewage pump for primary filtration; The separation host is mainly composed of Class I oil separation device and Class II oil separation device.
