Problems solved by technology

Activated carbon is dirty and requires pre-soaking, long contact times, and frequent replacement
However, the use of flocculants has problems such as increasing the salt content of sewage, generating a large amount of waste residue, and using a large amount of chemicals.
In addition, traditional gravity-based water-oil separation methods are often time-consuming

Abstract

The invention discloses an oil-water separation device, comprising a surfactant adding device, a combined filter and a probe, wherein a surfactant is water-based ethanol, and the combined filter consists of multiple universal filters arranged side by side. Each universal filter is an EUTEC filter. The surfactant is AR-grade water-based ethanol. The oil-water separation device also comprises a nano adsorbent. The oil-water separation device is simple to operate, high in oil-water separation efficiency, small in generation amount of waste residues, and small in agent used amount, and can effectively remove oil in oily sewage.

Description

technical field [0001] The invention relates to an oil-water treatment device and method, in particular to an oil-water separation device and method suitable for petrochemical and environmental protection fields. Background technique [0002] Oil-water separation equipment is widely used in petrochemical, environmental protection and other fields. For the petrochemical field, as oilfield development enters the middle and late stages, the water content of crude oil has increased significantly, and efficient oil-water separation methods are required. In addition, in order to improve the recovery rate, oil fields are usually injected with chemical agents, which makes the oil-water mixture in an oil-in-water emulsified state, which brings great difficulties to separation. In the field of environmental protection, the treatment of oily sewage is also a big challenge. [0003] Traditional oil-water separation uses activated carbon or flocculants. Activated carbon is dirty and r...
