Abstract

The invention relates to a kitchen wastewater oil-water separation device. The shell is provided with a water inlet pipe; a first vertical plate (5) and a second vertical plate (6) are arranged in the shell to sequentially constitute a first oil-water separation region (7), a second oil-water separation region (8) and a water collection region (9); the upper part of the first oil-water separation region is communicated with the upper part of the second oil-water separation region; the lower part of the second oil-water separation region is communicated with the lower part of the water collection region; a stirring component (10) is arranged in the first oil-water separation region, an oil collection tank is arranged on the upper part of the second oil-water separation region, and the upper part of the water collection region is provided with a water collection tank; side plates of the water collection tank are weir plate components (11) capable of adjusting waterflow liquid level; mobile weir plates (13) in the weir plate components (11) can move horizontally along fixed weir plates (12); the mobile weir plates can be moved to adjust the waterflow liquid level; and a sloping plate component (17) is arranged in the second oil-water separation region. The kitchen wastewater oil-water separation device has primary and secondary oil-water separation, has the characteristics of simple structure and high operation stability, can lower the manufacturing cost and is convenient for maintenance and cleaning.

Description

technical field

[0001] The invention relates to an oil-water separation device for oily wastewater, in particular to an oil-water separation device for high-concentration oily wastewater in the treatment of kitchen waste, and can also be used for oil-water separation of other types of oily wastewater. Background technique

[0002] The oily wastewater produced during the treatment of kitchen waste is characterized by the fact that the oil is mainly animal and vegetable oils with high oil content, while the oily wastewater produced by industrial production processes such as metallurgy and mechanical processing is mostly mineral oil.

[0003] Commonly used methods for oil-water separation include gravity method, centrifugation method, flotation method and so on. The structure of the existing oily wastewater oil-water separation device is different due to the different types or properties of the grease contained in the wastewater.
