A solid-liquid two-phase separation device and method using magnetic fluid and photocatalysis

Abstract

The invention discloses a solid-liquid two-phase separation device using magnetic fluid and photocatalysis. Along the flow direction of the liquid in the tube cavity, a magnetic induction coil is arranged on the outer wall of the tube body; the rear end of the tube body is transparent, and the top is arranged There is an illuminator that hangs down from the tube body; the end of the tube body hangs down from the conical filter. TiO 2 / PANI / Fe 3 o 4 The water-based magnetic fluid and alkaline printing and dyeing wastewater are fully stirred evenly by the spoiler and then input from the inlet port; the magnetic field strength in the tube is controlled by adjusting the current of different strengths in the coil; the ultrasonic flowmeter can obtain the concentration of catalyst particles, and the grating spectrometer The photon and its distribution can be calculated; the conical filter collects the solid residue; the invention uses magnetic fluid, ultrasonic wave and grating to separate the solid-liquid phase of the wastewater, and completes the photocatalytic degradation reaction at the same time. The pH value is obtained. The equipment has a compact structure, is easy to operate, can use solar energy, is energy-saving and green, and has strong practicability.

Description

technical field [0001] The invention relates to a solid-liquid two-phase separation device, in particular to a solid-liquid two-phase separation device and method using magnetic fluid and photocatalysis, and belongs to the technical fields of solar energy utilization technology and printing and dyeing wastewater treatment. Background technique [0002] The textile industry is one of the oldest industries in my country's national industries. [0003] In the production process of the textile industry, a large amount of wastewater will be produced, among which the pollution of printing and dyeing wastewater is the most serious. Textile printing and dyeing wastewater has the characteristics of large discharge, high content of organic pollutants, high alkalinity, and complex changes in water quality. It is recognized as one of the difficult-to-treat wastewater and has attracted widespread attention in the world today. [0004] The commonly used methods for treating printing and ...
