Problems solved by technology

[0005] At the same time, because the carbon fiber preparation process includes carbonization or graphitization, the carbon atom stacking orientation on the carbon fiber surface is more consistent, and the atomic layer spacing is smaller, so the fiber surface is non-polar and chemically inert. In addition, the carbon fiber surface has hydrophobic, Shortcomings such as smoothness and low adsorption performance lead to poor interfacial bonding between carbon fiber and its composite material

Embodiment Construction

[0021] A preparation method for oily wastewater adsorption material, comprising the following steps:

[0022] (1) Mix polytrimethylene phthalate and bisphenol A epoxy resin in a mass ratio of 1:3.5, heat to 110°C, stir until completely dispersed, cool down to 70°C, and then add the mixed liquid system quality 3% p-cumyl polyether base sulfonate, stirred for 40 minutes to obtain a premix for subsequent use;

[0023] (2) Put the spinning solution in the electrospinning apparatus, wrap the receiver with aluminum foil, and collect the as-spun fibers on the aluminum foil. The process parameters of the spinning process are positive pressure 15kV, negative pressure 1.5kV, and advance rate 0.04 mm / min, the receiving rate is 30r / min, the distance between the needle and the receiver is 15cm, and the ambient temperature is 30°C. After the spinning is completed, let it stand at room temperature for one day to obtain the as-spun fiber, and then place it in an oven to raise the temperature....

Abstract

The invention discloses a preparation method of an adsorbing material for oil-containing wastewater. The adsorbing material is prepared from polytrimethylene terephthalate, bisphenol A epoxy resin, vinylbenzyl trimethylammonium chloride, coconut shell, phenol, polyvinyl alcohol and the like. The preparation method comprises the following steps: preparing a porous carbon fiber from the coconut shell; carrying out modification treatment for multiple times to obtain a porous carbon fiber with high mechanical strength and high adsorptivity; combining the porous carbon fiber with the vinylbenzyl trimethylammonium chloride with excellent affinity to obtain an oil adsorbing elution material with good physical chemistry stability and excellent mechanical strength. With stability, the adsorbing material is suitable for being applied under various complex environmental conditions, has good environmental and economic benefits and is easy for large-scale production.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a method for preparing an oily wastewater adsorption material. Background technique [0002] Oily wastewater is a common industrial wastewater that mainly comes from the process of oil extraction, oil refining, oil storage, transportation and petrochemical production in the petroleum industry. It has many types of pollutants, high concentration, difficult biodegradation and high residue. After the water body, a water film will be formed on the surface to prevent oxygen from dissolving into the water body, resulting in the lack of oxygen in the water body, the death of organisms, and serious environmental pollution. In particular, the stench produced seriously pollutes the environment and endangers human health. At present, due to the large amount of wastewater produced by the crude oil industry and its complex composition, especially its high concentration of phenols, sul...
