    Application of macroporous adsorption resin in sewage treatment

    kinglv2018-07

    There are many harmful substances in the wastewater. In order to remove these harmful substances, some adsorbents are often used in water treatment projects.

    Conventional adsorption materials such as activated carbon, activated lignite, quartz sand, clay and zeolite mostly have low adsorption capacity, poor regeneration performance and selectivity, and cannot meet environmental protection requirements.

    As a well-known environmental protection equipment service provider, Kinglv environmental protection co., LTD. has many cases of domestic sewage treatment projects. The following is a high-performance polymerization adsorbent macroporous adsorption resin.

    Macroporous adsorbent resin is a porous three-dimensional structure having stable physicochemical properties, a large surface area and high adsorption capacity, selectivity and superior features, It is widely used in environmental protection fields such as heavy metal ion adsorption, wastewater treatment, pesticide adsorption and so on.

    The adsorption of macroporous adsorption resin is mainly physical adsorption, which is essentially the surface energy of surface molecules due to uneven force, which ultimately leads to the adsorption function of the surface. Surface adsorption is usually adsorbed in an aqueous solution, and its adsorption amount is affected by the surface area and the active site in contact with the adsorbed molecules, which is the result of van der Waals attraction or hydrogen bonding. The macroporous adsorption resin with porous structure has adsorption and screening effects on substances of different molecular weights, and different molecules are eluted by a certain eluent to achieve separation, impurity removal, purification and concentration.

    The macroporous adsorption resin has been widely used due to its strong adsorption capacity. In particular, it has a high adsorption amount for pollutants such as halogenated hydrocarbon compounds, nitro compounds, phenolic compounds, and organic acid compounds in wastewater. With the continuous emergence of new macroporous adsorption resins and the rapid development of adsorption technology, macroporous adsorption resins play a major role in water treatment.
