Description

technical field

[0001] The invention relates to a device for discharging sewage and separating oil and water from kitchens such as canteens, hotels and restaurants, and belongs to the field of water treatment. Background technique

[0002] With the improvement of people's living standards, the number of hotels, restaurants, and guesthouses has increased accordingly. The oil in the kitchen waste sewage discharge has not been separated and recycled, and it is directly discharged into the surrounding rivers and lakes, which is likely to cause blockage of sewer pipes and lead to serious water environment. pollute. It can be seen that separating and collecting the dirty oil in the kitchen drainage is an important measure to prevent water resources from being polluted, and effectively solves the secondary pollution caused by the dining table.

[0003] At present, the method of removing oil from kitchen waste sewage generally adopts the method of grease trap. Its main disadvantage...
