Description

Detachable and washable energy-saving purification device for oilfield wastewater Technical Field The utility model belongs to the technical field of oilfield wastewater purification, and relates to an energy-saving purification device for detachably cleaning oilfield wastewater. Background The treatment of oily wastewater is a technology for purifying oily wastewater produced in petroleum, chemical industry, steel industry and the like, and the main treatment objects comprise four types of pollutants, namely floating oil (particle size is larger than 100 microns), dispersed oil (10-100 microns), emulsified oil (smaller than 10 microns) and dissolved oil (smaller than 0.1 microns). The treatment process is generally divided into a primary stage and a deep stage, and the technology is originated from the industrial wastewater treatment requirement and is gradually refined along with the improvement of environmental protection standards. The utility model provides an oily waste water's purifier in oil field oil recovery production that current bulletin number is CN220537552U, includes first purification bucket, be provided with the second purification bucket on one side edge of first purification bucket, its characterized in that, first purification bucket with pass through the pipe intercommunication between the second purification bucket, the second purification bucket is close to top department and installs oil drain pipe, the second purification bucket is close to bottom department and installs the drain pipe, second purification bucket bottom department is provided with the evacuation mouth, and evacuation mouth department is provided with the valve, and this technique produces the deposit of filth and adsorbs at the section of thick bamboo wall easily in waste water treatment, influences separation efficiency and quality to and seal purification bucket unable dismantlement washing, and continuous treatment effect is poor.
