Study on environmental nanomaterials in food industry wastewater

Abstract

In recent years, with the rapid development of the food industry, the accompanying food wastewater pollution has become increasingly serious, which has become one of the most important sources of industrial wastewater and even water pollution in China. However, the traditional food wastewater treatment technology has gradually been unable to meet the needs of social development, and the development of cheap, convenient, and efficient food wastewater treatment technology has become a current research hotspot. Nanomaterials are capable of absorbing or degrading pollutants more than conventional materials. The innovation of water supply treatment technology has brought good opportunities. Due to its adjustable chemical form, it can realize the regulation of various excellent properties such as hydrophobicity, low dimension, photothermal conversion capacity, catalytic activity, and adsorption capacity, etc., which is very suitable for the removal of major pollutants in food industrial wastewater. The excellent adsorption properties and optical properties of different materials have realized the efficient removal of major pollutants from food industrial wastewater.
