Abstract

The invention belongs to the technical field of wastewater treatment and relates to a wastewater treatment device facilitating the separation and the recovery of a magnetic nanometer catalyst. Concretely speaking, the wastewater treatment device provided by the invention comprises a wastewater treatment part and a magnetic/aeration separation part, wherein the wastewater treatment part comprises a shell, a reaction vessel and a stirring device; the magnetic/aeration separation part comprises an aeration tank, an aeration device and an electromagnet. After reacting in the wastewater treatment part, the magnetic nanometer catalyst together with treatment wastewater and generated sludge jointly enters the aeration tank and is separated and recovered from a reaction system through the aeration/magnetic separation process; the treatment device is provided with simple accessories, is convenient to mount, convenient to run and maintain and simple in operation process and can meet the requirements of industrial continuous and large-scale production, so that the time and the cost are saved.

Description

technical field [0001] The invention belongs to the technical field of waste water treatment and relates to a waste water treatment device which is beneficial to the separation and recovery of magnetic nanometer catalysts. Background technique [0002] At present, with the rapid development of cities and industries, the water resource environment on which human beings rely is polluted to varying degrees and increasingly serious, among which urban domestic sewage and industrial production wastewater are the main sources of water pollution. The pollutants contained in these sewage (waste) waters have high concentrations, many types, high toxicity, and complex structures. Traditional physical and chemical treatment methods and biodegradation methods cannot completely degrade or transform pollutants. [0003] Advanced oxidation technology (AOPs) is a new technology emerging in the field of water treatment in recent years. It has been widely used because of its advantages such as...
