Oil-water separator

Abstract

The invention discloses an oil-water separator comprising a water inlet, a water outlet, a container, a movable filter residue bucket, a fixed filter net, an oil storage area, a vortex shallow filter, a sludge bucket, an electronic integration controller, an oil suction port, a slag suction port and a biological filter disc, wherein the fixed filter net finely filters the wastewater; an oil drop of which the diameter is 10-100 microns is separated and ascended to the oil storage area in the vortex shallow filter; the sludge bucket concentrates the waste residue; the waste residue descends to the bottom of the sludge bucket to be gathered under the effect of gravity after participating on the sludge bucket; the oil suction port is used for absorbing oil; the slag suction port is used for absorbing the slag; the biological filter disc is used for discharging the residual sewage. By adopting the oil-water separator, the environment-friendly problem of emission of restaurant waste water is solved, so that the discharged water achieves the corresponding national emission standards, the congestion problems of drainage pipelines caused by waste oil wall built-up are solved, separated excessive oil impurities are solved, and the processing link of restaurant waste oil in specified use is reduced.

Description

Technical field

[0001] The invention relates to an oil-water separation technology, in particular to an oil-water separator and an oil-water separation method. Background technique

[0002] With the improvement of people’s living standards, the number of restaurants and snack bars has increased. The restaurant’s catering waste water is processed into the sewer to produce a large amount of catering waste, including waste oil, leftovers, leftover soup, etc. These catering wastes contain both oil and water. Discarding directly will cause waste of resources and easily pollute the environment. It is the current development trend to use oil-water separators to separate oil and water, give full play to the role of garbage, and realize the thorough treatment and resource utilization of oil-water mixed garbage.

[0003] The existing oil-water separator has shortcomings and shortcomings: the efficiency of oil-water separation is not high; the automatic oil collection and residue collection ...
