Summary of the treatment technology of heavy metals in livestock and poultry breeding waste

Abstract

Abstract With the intensive and large-scale development of livestock and poultry breeding industry in China, the amount of livestock and poultry waste is increasing year by year, and the environmental pollution caused by it is increasingly serious. There are a lot of heavy metals in livestock and poultry waste, which not only cause serious pollution to the environment, but also reduce the safety of agricultural products, and pose a threat to human health. Therefore, the livestock and poultry waste must be treated by appropriate technology, after removing heavy metals, it can be used as a resource in the future. This paper summarizes the technologies of heavy metal treatment of livestock and poultry waste, and puts forward suggestions for the development of heavy metal treatment technology of livestock and poultry waste.
