Abstract:According to the sources, characteristics and treatment requirements of non-ferrous metal heavy metal wastewater in China, the current situation of treatment technology is analyzed. The results show that there are mainly 6 usual treatment technologies, such as neutralization (iron salt), vulcanization, adsorption, ion exchange, membrane and biochemical methods. On this basis, the technology development trend is expounded. The environmental protection standard gradually promotes the treatment technology to the direction of deep treatment; The traditional treatment technology does not meet the development requirements of the new era, forcing the treatment technology to the direction of resource utilization. Unattended pollution control mode has become the future development direction.
