IntroductionIndustrialized microbial method was used for recovering valuable metals in heavy- metal sludge, including Cu, Zn, Ni, etc., to achieve safe disposal of sludge which contains heavy metals.This project has been identified by the provincial science and technology projects and solid waste industry association, it also awarded third prize of Guangdong Provincial Science and Technology, and was named a promotion of technology catalog in China Environmental Protection Industry Association.

InnovationMicrobial method was usedfor recycling Cu, Zn, Ni, etc., from heavy-metal sludge, high purity metal compounds or high purity metal products for industrial applications can be directly obtained, the solution is recycled in the entire process, acid is avoided to use, and ultimately harmless sludge is achieved.

Application Prospect:Industrialized repair for Cu, Zn, Ni, etc., high concentrations of heavy metals in polluted soil,experiments have been carried out in pilot trial, it is the promotion of industrialization.
