Abstract

The invention relates to a preparation method of a sponge structure iron / SiC particle-based oil-water separation enhancement layer material capable of being applied to separation treatment of oily sewage on a large scale. The preparation method comprises the steps of preparing a sponge structure iron / SiC nano particle matrix through composite electrodeposition; and preparing a SiC nano particle super-hydrophobic / super-oleophylic enhancement layer on the surface of the matrix through etching / modification. The method specifically comprises the processes of (1) composite electrodeposition of the sponge structure iron / SiC nano particle matrix; (2) surface etching of the sponge structure iron / SiC nano particle matrix; and (3) surface super-hydrophobic / super-oleophylic modification of the sponge structure iron / SiC nano particle matrix. A novel oil-water separation material prepared through the method has the characteristics that the specific surface area is large, the oil and water separation efficiency is high, and the separation treatment process of the oily sewage is environment-friendly, and can be applied to separation treatment of oily sewage on a large scale.

Description

Technical field [0001] The invention relates to the field of oil-water separation materials, in particular to a preparation method of a sponge structure type iron / SiC particle-based oil-water separation enhancement layer material. Background technique [0002] With the development of economy, the pollution of oily sewage caused by oil production sewage, catering sewage, and marine oil transportation leakage pollution has become more and more serious, and has seriously threatened the safety of humans and the ecological environment. Therefore, the treatment of oily sewage is an urgent problem to be solved. Traditional methods for treating oily wastewater include: gravity separation, biological treatment, chemical treatment, and gas removal. The separation efficiency of these treatment technologies needs to be improved, and some of them require the addition of chemicals, which causes secondary pollution to the environment. Therefore, it is of great significance to develop new envi...
