Introduction: China is the world's largest leather producer, accounting for about 23.33 of global leather production % . At the same time, the tanning industry is also a major contributor to light industry in China, with pollution hazards second only to papermaking. Finding the balance between economic development and environmental protection is our main task at this stage. Pollution in the tanning industry is mainly reflected in wastewater, which is not only a large amount, but also a complex, high-concentration organic wastewater. In recent years, scientific research institutes, engineering companies and other institutions have carefully researched and developed many new advanced technologies based on China's basic national conditions and based on China's basic national conditions. This topic analyzes the current technologies of tannery wastewater treatment, and selects the most practical and effective technologies.
