Problems solved by technology

Whether it is industrial sewage or domestic sewage, improper treatment will cause serious damage to the environment. In the existing sewage treatment technology, the method of adsorption is commonly used to treat sewage. However, the adsorbate that adsorbs sewage is very easy to absorb and saturate. The pollutants are released again, so the adsorbent often needs to be replaced frequently; in addition, the existing sewage treatment often uses filter mats to intercept and filter the sewage in the direction of sewage flow, which will seriously affect the sewage discharge capacity

Abstract

The invention provides an efficient sewage treatment material and a preparation method thereof. The efficient sewage treatment material comprises a honeycomb formed by mutually connecting a pluralityof hollow tubes, a filter screen layer is arranged on the inner wall of each hollow tube, a filter ball is arranged between the filter screen layer and the inner wall of each hollow tube and comprisesa core, an adsorption layer and a shell layer, the core is made of activated carbon particles, the adsorption layer is made of adsorbent resin and wraps the core, the shell layer is arranged outsidethe adsorption layer and provided with adsorption holes, and the adsorption holes penetrate the shell layer and reach the adsorption layer. The efficient sewage treatment material can effectively adsorb pollutants in sewage without affecting sewage discharge capacity, desorption of the pollutants and water pollution caused by the desorbed pollutants again under the condition of water flow disturbance are effectively decreased, long-term sewage treatment can be ensured, frequent replacement of the efficient sewage treatment material is omitted, and the efficient sewage treatment material has the advantages of strong adsorption capacity, long service cycle and wide application range.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a high-efficiency sewage treatment material and a preparation method thereof. Background technique [0002] With the development of industry and the rapid increase of population, the problem of water pollution has become increasingly serious and constantly threatens human beings. Whether it is industrial sewage or domestic sewage, if it is not treated properly, it will cause serious damage to the environment. In the existing sewage treatment technology, the method of adsorption is commonly used to treat sewage. The pollutants are re-released, so the adsorbent often needs to be replaced frequently; in addition, the existing sewage treatment often uses filter mats to intercept and filter the sewage in the direction of sewage flow, which will seriously affect the sewage discharge capacity. Contents of the invention [0003] In order to solve the problems in the above bac...
