Abstract

The invention provides an oily living water purification device, and belongs to the technical field of water purification. The purification device is of an oil drum structure formed by slices with microporous arrays, the inner surfaces of the slices have super-hydrophilicity / super-lipophobicity, and the outer surfaces of the slices and microporous inner walls have super-hydrophobicity / super-lipophilicity. The invention further provides a preparation method of the purification device. The preparation method includes the steps: 1) processing the microporous arrays on the slices; 2) performing surface fluorination treatment on the slices and modifying the slices into slices with super-hydrophobic double surfaces; 3) removing inner surface fluorination by laser, changing the inner surfaces tobe super-hydrophilic and keeping super-hydrophobicity of the outer surfaces and the microporous inner walls; 4) finally, processing the slices into drum shapes and forming openings. The inner surfacesand the outer surfaces of the microporous slices have super-hydrophilicity after microporous processing. The device is simple in structure, the preparation process is simple, accurate and controllable, secondary pollution is avoided, and oil separated by the device can be recycled while environments are protected.

Description

technical field [0001] The invention belongs to the technical field of domestic water purification, in particular to an oily domestic water purification device and a preparation method thereof. Background technique [0002] With the improvement of human living standards and the rapid development of the catering industry, the discharge of oily domestic sewage is also increasing, which aggravates the pollution to the environment. In order to prevent oily domestic water from clogging the sewer, avoid the breeding of rodents and odors caused by the accumulation of oil in the sewer, and cumbersome and inconvenient cleaning work, and effectively prolong the service life of the sewer, it is necessary to purify the oily domestic water. [0003] The existing oily wastewater treatment methods are mainly through physical and chemical methods, chemical methods, biological methods and so on. There are certain limitations in these treatment methods: as the flocculation process in the che...
