Study on Treatment Method of Waste water Containing Heavy Metal Ions
With the rapid development of industrialization and urbanization,the discharge of heavy metal ions in wastewater poses a serious threat to the environment and human health.This review summarizes the treatment of heavy metal ions in wastewater by chemical precipitation,adsorption,ion exchange,membrane separation,solvent extraction,electrolysis and ionizing irradiation.Each of these methods has advantages and disadvantages,and suitable methods need to be selected according to the characteristics and treatment requirements of heavy metal wastewater to be treated.The future research direction should focus on the development of efficient,low-cost and environmentally friendly heavy metal ion treatment technology,and the research on the treatment and resource utilization of by-products in the treatment process should be strengthened.
