A magnetic fluidized bed wastewater adsorption treatment device

Abstract

This case involves a magnetic fluidized bed wastewater adsorption treatment device, including an adsorption tower, the adsorption tower is in the shape of an inverted wine bottle, and the interior is filled with magnetic adsorbents. There is a feeding port on the top of the tower body, and there is a slender power riser between the tower body and the tower mouth of the adsorption tower; and a solid-liquid separation warehouse, which is also in the shape of an inverted wine bottle. An electromagnet is arranged at the tower neck of the solid-liquid separation chamber; the solid-liquid separation chamber communicates with the adsorption tower through a water outlet inclined pipe and a magnetic adsorbent return pipe. The fluidized bed equipment of the fluidized bed adsorption device provided in this case is small in size and large in production capacity; the magnetic material has a high proportion of mesopores, excellent adsorption performance and regeneration performance, large contact area with liquid in the adsorption tower, and high mass transfer rate ; The adsorption speed is fast, the adsorption efficiency is high, the cost is low, and the operation is simple when the wastewater is subjected to advanced treatment.

Description

technical field [0001] The invention belongs to the technical field of adsorption equipment, in particular to a magnetic fluidized bed wastewater adsorption treatment device. Background technique [0002] Industrial wastewater contains a large amount of harmful substances, high concentration of organic matter, and dark color, and must be treated before being discharged into rivers. Industrial wastewater treatment methods include redox method, ion exchange method, ultrafiltration membrane method, biological decolorization method, adsorption method and flocculation precipitation method, etc. Among them, the adsorption method is considered to be an efficient and simple method to solve water environmental pollution, and it is the most widely used. Magnetic adsorbents are usually used in conjunction with large equipment to achieve strong and effective water treatment. [0003] With the rapid development of modern social economy, ordinary activated carbon magnetic adsorbents can...

Problems solved by technology

However, the current fluidized bed treatment system generally has the following defects: 1. The single-stage purification treatment method is adopted, which has low purification capacity and low sewage treatment efficiency; 2. The single treatment method in the fluidized bed cannot adapt to the depth of industrial wastewater deal with
