Abstract

The invention relates to a quartz sand filter material with excellent oleophylic and hydrophobic properties and a preparation method thereof. The quartz sand filter material is obtained by performing surface modification on quartz sand through a surface modification liquid, then performing self-assembly of a molecular film through a self-assembly liquid, and finally performing composite modification through an iron-copper modification liquid. The surface modification liquid is mainly prepared from the following components by mass: 390-400 parts of anhydrous ethanol, 25-28 parts of tris(hydroxymethyl)aminomethane, 1.5-1.6 parts of nano zinc oxide and 0.002-0.003 part of dopamine hydrochloride; the self-assembly liquid is mainly prepared from the following components by mass: 5-20 parts of a coupling agent and 80-100 parts of a solvent. According to the quartz sand filter material with excellent oleophylic and hydrophobic properties and the preparation method thereof, the formula is reasonable, the quartz sand filter material which is high in surface roughness, has a super-hydrophobic surface, is excellent in lipophilicity and high in oil removal efficiency and has the capacity of removing micro-pollutants in water is prepared, the preparation process is simple, large-scale production is easy, and the application prospect is wide.

Description

technical field [0001] The invention belongs to the technical field of quartz sand, and in particular relates to a quartz sand filter material with excellent lipophilic and hydrophobic properties and a preparation method thereof. Background technique [0002] As a kind of inorganic particles that widely exist in nature, quartz sand filter material has high surface hardness, strong mechanical stability, good pollution interception performance, low price and easy purchase. It is a commonly used natural filter material for sewage treatment. With the continuous development of my country's industrial technology, oily substances and organic solvents are used more and more frequently in daily life and industrial production, and the production scale of waste oil is increasing day by day, but limited by the lagging behind in the development of industrial production technology , Insufficient management level of the production discharge process and other reasons cause a large amount of ...
