Environmental pollution mainly includes waste gas, liquid waste and solid waste. If not treated timely and effectively, it will cause pollution to rivers, atmosphere and soil. Due to human factors, the composition or state of the environment will change and the environmental quality will decline, thus disturbing and destroying the ecological system and the normal production and living conditions of human beings.
Ion-exchange resins have been used in many environmental protection issues of great concern.Currently, many aqueous or nonaqueous solutions contain toxic ions or nonionic substances that can be recycled using resins.
In waste gas treatment, it can be used to remove sulfur dioxide, formaldehyde and other substances in waste gas, as well as organic gases in the atmosphere and small molecules of halogenated hydrocarbons and VOC in waste gas
In wastewater treatment, firstly, it can be used to remove heavy metals and recover precious metals, such as removing metal ions in electroplating waste liquid, such as copper, nickel, mercury, chromium, lead, zinc and other heavy metals.Recovery of gold, silver, platinum group metals and other precious metals in waste liquid can not only protect the environment, but also realize resource reuse.Secondly, it can be used for organic wastewater treatment, to remove phenol, aromatic group, aliphatic group and other organic pollutants in the wastewater. In addition, it can also remove inorganic pollutants in the wastewater, such as nitrate, inorganic phosphorus, borate, sulfate, ammonia nitrogen and so on.
