The invention discloses a magnetic control nano motor overflowing adsorption reaction assembly, which comprises a shell with an interlayer, an inlet and an outlet are formed in the two ends of the shell, a plurality of magnetic field generators are symmetrically arranged in the interlayer of the shell to form a magnetic bound area, an adsorption magnetic nano motor is placed in the magnetic bound area, in the magnetic field, the adsorption magnetic nano motor is suspended, dispersed and bound in the magnetic bound area, fluid containing pollutants flows through the magnetic bound area, and fluid purification is realized under the combined action of the magnetic field and the adsorption magnetic nano motor; when a fluid flows through the magnetic bound area, pollutants in the fluid are adsorbed, captured and filtered by the magnetic nano-motor, and the nano-motor does not flow away along with the fluid; and the device is simple in structure, easy to operate and suitable for industrial production and market popularization and application.

Description

technical field [0001] The invention belongs to the technical field of pollutant treatment, and in particular relates to a magnetically controlled nanomotor overcurrent adsorption reaction component and an application thereof. Background technique [0002] With the continuous development of living standards and industrial production, most cities in my country have serious heavy metal wastewater pollution problems. More and more pollutants have gradually affected human production and life. The existing pollutant treatment technologies mainly Adsorption, absorption, catalytic conversion, etc. Most of the traditional adsorption, absorption, and catalytic conversion technologies have high cost, low efficiency, and easy to cause secondary pollution. However, the treatment of pollutants has become a major problem in the world today. Heavy metals are a type of residual cumulative pollutants. Due to the pressure from multiple environments such as industry, agriculture, transportation...
