Introduction: In recent years, China's synthetic leather industry has developed rapidly, but the pollution of synthetic leather in the production process cannot be ignored. The wastewater contains organic substances such as DMF (dimethylformamide), toluene, methyl ethyl ketone, and dimethylamine. These pollutants have high concentrations, complex components, and stable molecular structures and properties. Therefore, the overall biochemical effect of the wastewater is poor and it is a difficult organism Degradation of wastewater. The DMF organic waste gas produced by the synthetic leather production line has the characteristics of low concentration, fugitive emissions, and high odor. Because DMF is expensive and easily soluble in water, pollution treatment is mainly performed for recycling purposes. This topic collects and sorts out the most practical and advanced synthetic leather wastewater waste gas treatment technology in China for your reference.
