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 filtering type oil-water mixture separation oil trap device, which comprises an oil-water separation box shell, a backflow baffle, an oil-water separation membrane, an oil-water separation membrane support net, a funnel-type tank bottom shell, a baffle plate, an oil-water separation The area where the separation membrane is located is the filter area, the upper part of the filter area is the oil slick area, the lower part of the filter area is the buffer settlement area, the oil outlet is equipped with a backflow baffle, and there is an oil-water separator that can be adjusted up and down and placed at a distance from the oil-water separation membrane support net. The separation membrane group, the two sides of the baffle plate are the feed port and the discharge port of the oil-water mixture, and the bottom of the funnel bottom shell is the sewage discharge port. The area where the baffle is located is the oil-water-solid particle buffer settlement area. There is a main valve at the water inlet, and the sewage outlet set under the sediment buffer settlement area has a mud discharge valve, and the mud discharge pipe is connected to the sewage outlet in turn. By adjusting the position of the oil-water separation membrane, the invention is suitable for the separation of oil and sewage with different concentrations, can realize efficient separation of oil, water and sediment, and is convenient for waste water treatment and resource recycling.

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 in the technical field of sewage treatment. Background technique [0002] Petroleum industry and petrochemical industry discharge waste water containing a large amount of oil in the production process, coal coking and gasification industry discharge waste water containing high concentration of tar, wool spinning industry and meat industry discharge waste water containing more oil, catering industry every year A large amount of wastewater containing oil will also be produced, and the concentration of oil content can reach 400-500mg / L, or even higher. If these oily wastewaters are discharged into water, they will cause pollution, degrade the water quality, and deteriorate the environment. Therefore, the oily wastewater should be degreased before discharge. At present, the methods of oil removal mainly include ...
