[0002] Aluminum industry wastewater refers to wastewater, sewage and waste liquid generated during the aluminum production process. The wastewater contains metal ions and organic pollutants. If it is directly discharged into the external environment, it will seriously pollute the local water quality and endanger human health. With the increase in the demand for new water and the amount of wastewater discharged by the aluminum industry, the consumption of water resources and the pollution of the environment are becoming more and more serious. If the wastewater is not reused, it will not only waste a lot of fresh water resources, but also increase the production cost of aluminum processing.
