Problems solved by technology

In the existing industrial sewage oil removal system, oil separation equipment such as advection oil traps, inclined plate oil traps, and float oil skimmers have been widely used, but they cannot be automatically adjusted according to the oil content in the sewage. Grease trap, the field of application is also relatively limited

Abstract

The invention discloses an adjustable filtration type oil separating tank device for separating oil-water mixture. The oil separating tank device comprises an oil-water separation box shell, a backflow baffle, an oil-water separation film, an oil-water separation film support net, a funnel type box bottom shell and a deflection baffle, wherein an area of the oil-water separation film is a filtration area; the upper part of the filtration area is a flotation oil area; the lower part of the filtration area is a buffering and settling area; the backflow baffle is arranged at an oil outlet; an oil-water separation film set which can be adjusted up and down and is spaced from the oil-water separation film support net is arranged; an oil-water mixture inlet and a water outlet are formed in two sides of the deflection baffle respectively; a sewage outlet is formed in the bottom of the funnel type box bottom shell; the area of the deflection baffle is an oil-water-solid particle buffering and settling area; a master valve is arranged at the water inlet; a sludge discharging valve is arranged at the sewage outlet located under a sludge-sand buffering and settling area; a sludge discharging pipe is connected with the sewage outlet in turn. The adjustable filtration type oil separating tank device is suitable for separating different concentrations of grease sewage by adjusting the position of the oil-water separation film; the oil, water, sludge and sand can be efficiently separated; the wastewater treatment and the resource regeneration and utilization can be facilitated.

Description

technical field [0001] The invention relates to a waste water treatment device, in particular to a sewage separation treatment device with oil content, which is applied to the technical field of sewage treatment. Background technique [0002] The petroleum industry and petrochemical industry discharge waste water containing a large amount of oil in the production process, the coking and gasification industry of coal discharges waste water containing high concentration tar, the wool spinning industry and meat industry discharge waste water containing more oil, and the catering industry discharges waste water containing more oil every year. A large amount of waste water will also be produced, and the concentration of oil content can reach 400-500 mg / L, or even higher. These oily wastewater will cause pollution if discharged into the water, which will deteriorate the water quality and the environment. Therefore, the oily wastewater should be de-oiled before being discharged. A...
