The oilfield poly-surfactant flooding sewage treatment process comprises the following specific steps: 1, performing stabilizing regulation on water quality and water amount of inflowing water by using an inflowing water buffer tank; 2, removing oil slick and most of dispersed oil from water by using a primary swirling static flotation column; 3, mixing outflowing water obtained in the step 2 with a flotation agent through a pipeline, entering a secondary swirling static flotation column, and further removing the dispersed oil, emulsified oil and suspended solids from water; and 4, sending the sewage treated in the step 3 into a two-stage double-filtering material filter, filtering till and the treated sewage reaches a pouring standard for a high-permeability strata, namely the oil content is less than or equal to 20mg/ L, the suspended solid content is less than or equal to 20mg/ L and the median particle size is less than or equal to 5 microns. By the oilfield poly-surfactant flooding sewage treatment process, the oil removing time is greatly shortened, the floor area is reduced, only a little of flotation agent is added in a running process, the maintenance is simple, and the outflowing water is stable and qualified.

A separation device with a gas inlet port that accepts an inlet gas. The inlet gas is composed of a mixture of at least two separable particle components with each component having a different mass. A rotating separation rotor accepts the inlet gas and uses a separator to substantially separate the gas according to mass into two fractions, a heavier and a lighter fraction. One of the fractions is passed to a second separator that further separates that fraction into another two fractions consisting of heavier and lighter fractions. The desired fractions are collected and exhausted from the separation device for use.

The invention refers to a female part of a snap fastener including a first reception area (15) for locking a first male part (40). According to the invention, the female part further includes a second reception area (16) for locking a second male part (46, 47) is provided.

A wash stand comprising a wash basin having a drain opening which opens into a drain chamber. In the drain opening there is a cover which extends over part of the drain opening such that, at least in a lower region of the drain opening, a gap is created through which water can flow out of the wash basin into the drain chamber.
