Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a water advanced treatment device. Background technique [0002] With the extensive use of synthetic chemicals (such as pharmaceuticals and personal care products, detergents, pesticides, etc.), some of them will be discharged into natural water bodies through urban drainage systems, bringing potential ecological and environmental risks. Such pollutants usually have the characteristics of low concentration (<1mg / L), small molecular weight (<500Dalton), high solubility and strong persistence, and are also called micropollutants. Studies have shown that traditional water treatment technologies such as coagulation, sedimentation, filtration, and biodegradation have low removal efficiency for micro-pollutants and cannot meet the requirements for deep purification of drinking water. At present, membrane separation technology and advanced oxidation m...
