Status of Chromium Pollution and Prevention-Treatment Technology in Leather Industry
Abstract:Chromium pollution has been restricting the sustainable and healthy development of leather industry, which is a huge obstacle that must be overcome. This article briefly describes the hazards, sources and control of chromium pollution, and summarizes the research status of chromium pollution prevention and treatment technology in leather industry from source reduction , end treatment and resource utilization. Chromium pollution in leather industry not only needs to be effectively treated, but also be prevented by clean production technologies of leather-making that can effectively reduce chromium emission from the production source. In addition, resource utilization of chromium-containing pollutants in leather industry should be actively promoted.
Keywords: leather industry chromium pollution source reduction end treatment resource utilization
