Research on pollution status of dissolved organic matter and treatment technologies development

Dissolved organic matter is a kind of common water impurity that is very common in natural water bodies, such as lakes and rivers near urban areas. Although the activities of the biosphere produce some soluble organic compounds, human living also bring considerable amount of supernumerary compounds. Impurities that exceed the self-purification capacity of water bodies can cause water pollution, which in turn affects surrounding residential areas. Therefore, reducing the concentration of dissolved organic matter in water through filtration, or preventing the influx of artificial compounds into the water bodies has positive implications for urban ecology. This article proposes multiple feasible solutions based on the above two ideas, including the adapting and applying existing technologies, as well as involving high-tech that can be implemented in the near future. The paper focus on the filter materials such as granular activated carbon and graphene, also a more economic improvement of the application of water-soluble polymers.
