Abstract: Industrial wastewater with heavy metals poses a serious threat to the environment, and bio-adsorption can effectively remove heavy metals. This paper firstly introduced current research status of common agricultural and forestry wastes and the modified reagents on absorption of heavy metals, then analyzed the influencing factors on bio-adsorption and the adsorption process optimization, followed by summarizing the mechanism of bio-adsorption and the desorption process and introducing the thermodynamic and kinetic models and related parameters. Finally, we pointed out the existing problems and development prospects of bio-adsorption. Agricultural and forestry waste has the advantages of wide range of sources, low cost and renewable. When used in wastewater treatment, it can achieve the full utilization of resources, so it has a good prospect in industrial application.
