Abstract
With the rapid development of industrialization, the problem of heavy me tal wastewater discharge is becoming more and more serious, which poses a serious threat to the ecological environment and human health. High efficiency and environmental protection of heavy me tal wastewater treatment technology has become a research hotspot in the field of environmental science. As a new functional material, high performance adsorbent resin shows great potential in heavy me tal wastewater treatment due to its excellent adsorption, regeneration and stability. In this paper, the application status, technical principle and advantages of high performance adsorption resin in heavy me tal wastewater treatment were reviewed. High performance adsorption resins usually have unique chemical structures and functional groups, which can show high selectivity and adsorption ability for specific heavy me tal ions. In the process of heavy me tal wastewater treatment, through physical or chemical adsorption, the resin can quickly capture and fix the heavy me tal ions in the wastewater on its surface or internal channels, so as to achieve effective removal of heavy me tal ions. Compared with traditional heavy me tal wastewater treatment technology, high performance adsorption resin has many advantages. First of all, its adsorption capacity is large, the adsorption rate is fast, and it can treat a large amount of wastewater in a short time, improving the treatment efficiency. Secondly, the regeneration performance of the resin is good, and its adsorption capacity can be restored by simple regeneration treatment, so as to achieve recycling and reduce processing costs. In addition, the high performance adsorption resin also has the advantages of simple operation, small footprint, strong adaptability to water quality changes, etc., which is suitable for heavy me tal wastewater treatment projects of various scales. In practical applications, high-performance adsorbent resins have been widely used in the treatment of heavy me tal wastewater in electroplating, me tallurgy, chemical industry, mining and other fields. For example, in the treatment of electroplating wastewater, high-performance adsorption resins such as CH-90Na can effectively remove heavy me tal ions such as copper, nickel and chromium in wastewater, and meet environmental discharge standards. At the same time, by optimizing the selection and operating conditions of resin, the treatment effect can be further improved and the treatment cost can be reduced. The high performance adsorption resin has important application value and development prospect in the treatment of heavy me tal wastewater. In the future, with the continuous progress of material science and the increasing environmental protection requirements, the performance of high-performance adsorbent resins will continue to optimize and innovate, providing more efficient and environmentally friendly solutions for heavy me tal wastewater treatment.
