Technical Field

The utility model belongs to the technical field of water treatment facilities, a adsorption method water treatment facilities is related to.

Background

With the increase of population and the rapid development of modern industry, the problem of environmental pollution is increasingly serious, particularly the heavy metal pollution of water bodies directly endangers the health of human beings. According to the report issued by the world health organization, 300 to 400 million people die each year from diseases related to water pollution. The treatment of water pollution has become an important strategic target for the sustainable utilization of global water resources and the sustainable development of national economy at present.

The adsorption method is one of the main technical branches of water treatment technology, and has a wide application range, such as the fields of chemical industry, resource utilization, medicine and the like. The adsorption method for treating sewage is mainly to treat sewage by using an adsorbent (such as activated carbon) in a production process, and a corresponding adsorption device is usually required to be equipped. According to the difference of the working characteristics of the adsorption devices, the currently common adsorption water treatment devices can be divided into two types: fixed bed, fluidized bed.

The fixed bed is the most applied equipment in the water treatment device of the adsorption method at present, such as an adsorption tower, an adsorption bed and the like, but has the following defects:

(1) The adsorption column has large loading amount of the adsorbent, but the utilization rate is low. Because only the adsorbent in the working layer is undergoing adsorption or ion exchange reaction when the fixed bed is in operation, most of the remaining adsorbent can only serve as a "support", but when the adsorbent in the fixed bed needs to be regenerated, the upper adsorbent is in a failure state, and it is difficult to regenerate and recover the activity.

(2) Along with the increase of the height of the adsorption tower, the pressure drop of the fixed bed layer is increased, the adsorbent at the middle and lower parts is easy to break and pulverize, the water permeability at the bottom of the fixed bed is deteriorated after the adsorbent particles are broken, the full contact between target ions in water and the adsorbent is not facilitated, and the mass transfer efficiency is reduced.

As a supplement to a fixed bed adsorption water treatment device, although a fluidized bed has the advantages of sufficient solid-liquid phase contact and high mass transfer speed, the problems of violent friction and collision exist between adsorbent particles and between adsorbent particles and fluid, so that the particle adsorbent is broken, pulverized and abraded, and further fails.

Therefore, aiming at the problems of the existing water treatment device, the development and design of the novel water treatment device adopting the adsorption method, which is not only beneficial to the efficient utilization of the adsorbent, but also can avoid the massive abrasion of the adsorbent, have important significance.
