Description

Oil-water separator

Technical Field

The utility model relates to the technical field of restaurant sewage treatment, in particular to an oil-water separator.

Background

Along with the strict national requirements on the catering industry waste treatment policy, the catering industry waste treatment method ensures that the catering industry waste treatment meets the environmental protection requirement, and needs to discharge the rest waste water uniformly after the oil in the catering waste water is separated and recovered in a centralized manner so as to meet the national environmental protection requirement.

In the existing restaurant wastewater treatment system, an oil-water separator is generally required to be combined for separating floating oil from wastewater, so that the environmental protection requirement can be better met. Most of the existing oil-water separators have complex structures and low oil-water separation efficiency; and the liquid storage tank body structure of the existing oil-water separator is mostly of an upper end closing type (the caliber of the upper end is smaller than that of the lower end), so that the specific oil-water separating mechanism has corresponding limitation. In practical application, a plurality of liquid storage tanks with the same upper and lower calibers exist, and once the size of the liquid storage tank is large, the conventional oil-water separation mechanism can hardly meet the requirement of high-efficiency oil-water separation.
