[0066] According to a second aspect of the present invention, a method for preparing the above-mentioned porous nanocomposite oil-absorbing material is provided, comprising the following steps:

[0067] Nanomaterials with one-dimensional nanostructure arrays are grown on a three-dimensional porous material substrate by a hydrothermal method to obtain a three-dimensional porous material-nanomaterial composite, and then the three-dimensional porous material-nanomaterial composite is hydrophobically modified to obtain a porous nanocomposite Oil absorbent material.

[0068] The hydrothermal method is an effective method for synthesizing nanomaterials. The hydrothermal method is a method of reacting raw materials under certain temperature and pressure conditions in a sealed pressure vessel with water as a solvent.

[0069] The hydrothermal method is simple, easy to operate and can effectively control nanomaterials (such as MnO 2 ) crystal form, morphology and size, which can reali...

Abstract

The invention discloses a porous nano composite oil absorption material, a preparation method and application thereof, and an oily water treatment device, and relates to the technical field of oil absorption materials. The porous nano composite oil absorption material comprises a three-dimensional porous material substrate and nanomaterials distributed on the three-dimensional porous material substrate and provided with a one-dimensional nano structure array; and the porous nano composite oil absorption material is modified with hydrophobic substances. The preparation method of the porous nanocomposite oil absorption material includes the following steps that the nanomaterials with the one-dimensional nano structure array grow on the three-dimensional porous material substrate through a hydrothermal method so as to obtain a three-dimensional porous material-nanomaterial complex, and then the complex is subjected to hydrophobic modification to obtain the porous nano composite oil absorption material. The problems that existing oil absorption materials are low in oil absorption capacity and poor in oil reservation effect and cannot be recycled are relieved. The porous nano compositeoil absorption material can effectively absorb oil, is high in oil absorption capacity, can also adsorb heavy metal and organisms, and has the advantages of good oil reservation effect and cyclic utilization.

Description

technical field [0001] The invention relates to the technical field of oil-absorbing materials, in particular to a porous nano-composite oil-absorbing material, a preparation method and application thereof, and an oily sewage treatment device. Background technique [0002] Water body oil pollution refers to the pollution caused by oil (any type of oil, including animal and vegetable oil, mineral oil and its refined products) entering the water body environment through different channels. Oil-polluted water bodies are characterized by high chemical oxygen demand (COD) and biological oxygen demand (BOD), certain odor and color, flammable and easy to oxidize and decompose. The sources of oil pollution are very wide, mainly including industry, agriculture, transportation, and domestic sewage discharge and oil leakage, the settlement of petroleum hydrocarbons escaping into the atmosphere, and natural oil spills on the seabed. [0003] With the rapid development of industry, the ...
