Oil-water separating device

Abstract

The invention relates to an oil-water separating device which comprises a box body, an electrode plate, a hollow plate-type membrane and a microelectrolysis material layer. The electrode plate, the hollow plate-type membrane and the microelectrolysis material layer are fixed to the interior of the box body. The microelectrolysis material layer is placed on the periphery of the hollow plate-type membrane. A water outlet is formed in the hollow plate-type membrane. Tiny oil drops in wastewater can be exposed out and float on the water surface through electrolysis of the electrode plate, sewage obtained after oil is separated out is treated through the hollow plate-type membrane, and the standard for reclaimed water can be met. The oil-water separating device is simple in structure, small in occupied area, convenient to install and maintain and capable of being directly connected to an oily wastewater drainage pipeline of a mess, a restaurant and the like, and rapid and thorough oil and water separation can be achieved.

Description

technical field [0001] The invention relates to an oil-water separation device. Background technique [0002] Canteens, restaurants, etc. produce a large amount of kitchen swill every day, and most of the treatment methods are to directly discharge the swill into urban sewers. [0003] As we all know, the composition of swill is relatively complex, including oil, water and organic matter, but the main components are oil and water. If it is discharged directly without treatment, it will have a great impact on the environment. In particular, swill directly discharged to urban drainage pipes is easy It is collected and refined into "waste oil" by unscrupulous traders, and returns to people's tables, harming people's health. [0004] The country is currently strengthening the management of kitchen waste, promoting the installation of oil-water isolation tanks, oil-water separators and other facilities. However, most of the current oil-water separation methods use the principle ...

[0004] The country is currently strengthening the management of kitchen waste, promoting the installation of oil-water isolation tanks, oil-water separators and other facilities. However, most of the current oil-water separation methods use the principle of different specific gravity of oil and water to filter out the oil floating on the surface of wastewater. This method It can only remove the oil droplets floating on the surface of the waste liquid. For the water droplets with larger diameters, they need to stay for a long time to separate, and the tiny oil droplets in the waste water cannot be removed. The separation efficiency is low, the separation is not complete, and the separated water still exists. Many miscellaneous ingredients do not meet the standard of reclaimed water
