Research Progress on Resource Treatment and Recycling of Solid Waste Containing Chromium

In recent years, China has paid more and more attention to ecological and environmental protection, and the treatment of solid waste during industrial production has become more important. For example, stainless steel production industry, electroplating industry, chromium salt production industry, etc., will produce a large amount of chromium-containing solid waste. Long-term accumulation will not only occupy land resources but also cause serious harm to the environment. Therefore, it is particularly important to develop more effective methods for recycling and processing chromium-containing solid waste. This article summarizes the current situation of chromium ore resources in China, predicts the demand for chromium ore in the next few years, expounds the current situation and hazards of chromium-containing solid waste, and summarizes the new domestic and foreign chromium-containing solid waste treatment technologies in recent years. Research and progress in the recycling of chromium-containing solid waste, introducing the advantages and disadvantages of different treatment methods, in order to find a better way to recover and treat chromium-containing solid waste in the future.
