Abstract

The invention discloses a wastewater treatment process of oil-retaining emulsion liquid waste water, which adopts electrochemical demulsification. The technological process is as follows: the oil-retaining emulsion liquid waste water; grate pretreatment; adjustment of water quality and volume; electrochemical demulsification; oxidation or precipitation; filtration; clear water. The electrochemical demulsification and separation reaction pond during electrochemical demulsification has the advantages of continuous demulsification and separation, operation under normal temperature and atmospheric pressure, low operating cost, small occupied area of the complete equipment, convenient maintenance, easy operation, applicability to demulsification and separation of oil-retaining emulsion liquid waste water. The electrochemical demulsification has the advantages of integrated mode of ionization and chemical reaction, optimal demulsification effect, high oil-water separation efficiency, high decoloration efficiency, good effluent close to the standard of tap water examined by sensory organ, high water quality up to first class discharge standard and recyclability.

Description

technical field

[0001] The invention relates to a process for treating oily emulsion wastewater, in particular to a process for treating oily emulsion wastewater that achieves demulsification by means of electrochemical demulsification, and belongs to the field of purification and treatment of oily emulsion wastewater. Background technique

[0002] The mixed emulsification of oil and water exists in many industrial processes, and it is a phenomenon in which oil molecules and water molecules are contained in a liquid state. Oily emulsion wastewater is very harmful in the industrial process, such as: the unfavorable factors of blocking and corroding pipelines for its transportation pipelines (such as oil pipelines, etc.); when the wastewater is discharged, if the oily emulsion wastewater is not treated, it will be directly Discharge will not only seriously pollute surface water bodies and groundwater sources, destroy the ecological environment, but also...
