Abstract
Along with the rapid development of urbanization in China, a series of environmental problems have accompanied, especially industrial effluents containing heavy metals such as lead, cadmium, mercury, etc., which have caused great damage to water, soil and earth, and have caused great harm to human health. In this article, new processes such as adsorption, membrane separation, chemical precipitation, ion exchange, bio-adsorption, and bio-reduction are introduced. The technology has shown excellent results in a variety of working conditions, opening up new ways for the treatment of heavy metal pollution in water. The development of this topic is of great and urgent practical significance for the protection of ecological environment and the promotion of sustainable development in China.
