Description

Macroporous adsorption material desorption regeneration and aftertreatment system

Technical Field

The utility model relates to the field of desorption post-treatment, in particular to a desorption regeneration and post-treatment system for a macroporous adsorption material.

Background

The organic matter in the high-salt wastewater often contains a large amount of toxic and difficultly-degradable substances, and the wastewater cannot be treated by the traditional biochemical method or cannot reach the discharge standard after being treated due to high salt content and high organic matter, so the prior upper evaporation technology is mainly adopted.

With continuous research, the requirement on treatment of the high-salt wastewater can be reduced by removing organic matters in the high-salt wastewater in advance, and at present, most of the high-salt wastewater is concentrated and separated after removing the organic matters by an activated carbon adsorption bed in order to reduce the content of the organic matters in the high-salt wastewater, but the adsorption of the high-salt wastewater to part of large-particle organic pollutants is insufficient due to the limitation of the adsorption pore size of the activated carbon.

After a new large-aperture adsorption material is developed, the organic matter can be more effectively adsorbed, a good desorption regeneration effect is achieved, and the low energy consumption requirement is met for the desorption treatment of the organic matter.

In view of the problems in the prior art, the utility model designs and manufactures a desorption regeneration and post-treatment system of a macroporous adsorption material by combining years of design and use experience in the related field and assisting with over-strong professional knowledge, so as to overcome the defects.
