The Importance of Wastewater Treatment
Water is the source of life. With the continuous development of urban economy, the problem of continuous shortage of water resources has gradually emerged. Wastewater treatment facilities are very basic facilities in modern cities and play a very important role in protecting the water environment. Therefore, strengthening the construction and maintenance of wastewater treatment facilities is of great significance to the sustainable development of modern cities.
Accelerate Research and Practice of Graphene in Wastewater Treatment
Heavy metal ions are a difficult point in wastewater treatment and recycling. The extremely large specific surface area of graphene materials can increase its contact area with water and effectively adsorb heavy metal ions in wastewater. The presence of too much organic matter in the water will reduce the oxygen content of the water, resulting in deterioration of water quality and water pollution. The negative charge properties of graphene oxide oxygen-containing groups can adsorb positive ions in dyes and enhance graphene's adsorption of organic dyes. At the same time, graphene as a high-performance carrier combined with TiO2 photocatalyst can improve photocatalytic performance and efficiently degrade organic matter in water. Organic solvents such as oil are also important sources of water pollution and soil pollution. Graphene has strong lipophilicity, high adsorption capacity, and high adsorption efficiency. It is conducive to the adsorption of organic solvents such as oil in wastewater.
