A method for liquefy wheat grains contain heavy metals and recovering electric energy

The invention discloses a method for liquefaction of wheat grains containing heavy metals and recovery of electric energy, belonging to the technical field of resource treatment of wheat grains containing heavy metals. A method for liquefying wheat seeds containing heavy metals and recovering electric energy includes such steps as liquefying wheat seeds containing heavy metals, assembling and starting microbial fuel cell, and utilizing hydrolysate of wheat seeds containing heavy metals to generate electric energy by microbial fuel cell. At that same time of recover electric energy, the COD ofthe effluent water can be reduce to below 250 mg/L, and the concentration of heavy metal ions in the effluent water completely meets the national level local sewage comprehensive discharge standard, so that the method has good application prospect. The invention effectively realizes the resource treatment of wheat grains containing heavy metals, can reduce the COD of the effluent water to below 250 mg/L while recovering e
