Problems solved by technology

[0004] Due to the large amount of pollutants in petroleum wastewater, it needs to be purified and treated when it is discharged. However, the existing petroleum wastewater treatment device has a relatively simple process, and the sediment after sedimentation cannot be discharged in time, resulting in internal blockage of the process, and for The treatment of metal cations in wastewater and the treatment of oil pollution are costly and the effect is not very good

Abstract

The invention discloses a wind separation method petroleum wastewater electroplating treatment device, comprising a base, a settling tank is arranged on the upper side of the base, the top of the settling tank is connected with a waste water inlet, and the settling tank is connected with a degreasing tank through a conduit. tank, the inner upper end of the flocculation tank is provided with a flocculant storage box, and the other side of the flocculation tank is connected to a filter tank through a conduit, and the bottom of the settling tank, oil removal tank, electrolysis tank, flocculation tank and filter tank are all covered With bottom box. In the present invention, the electroplating treatment device for petroleum wastewater by winnowing method is mainly composed of five processing procedures of a settling tank, an oil removal tank, an electrolytic tank, a flocculation tank and a filter tank. V-shaped tubes are installed at the bottom, so that the sediment produced by the treatment can easily settle into the bottom box at the bottom, so that there will be no blockage in the treatment process, so that the treated impurities can be discharged in time.

Description

technical field [0001] The invention relates to the technical field of petroleum wastewater treatment, in particular to a wind separation method petroleum wastewater electroplating treatment device. Background technique [0002] Petroleum wastewater mainly includes three aspects: petroleum mining wastewater, oil refining wastewater and petrochemical wastewater. Oily wastewater is discharged during the dehydration process of crude oil extracted from oilfields. This wastewater also contains a large amount of dissolved salts, and its specific composition is related to the geological conditions of oil-bearing formations. [0003] The composition of petrochemical wastewater is complex. The waste water from the cracking process is basically the same as the oil refinery waste water. In addition to oil, there may be some intermediate products mixed in, and sometimes cyanide. Due to the variety of products and different processes, the composition of wastewater is extremely complex....
