▎ 摘　　要

NOVELTY - Self powered heavy metal recovery device based on flexible aluminum air battery comprises aluminum negative electrode coating (2), hydrophilic filter membrane substrate (3) and current collector (5). The upper end of flexible aluminum air battery is connected with water inlet tank. The lower end is connected with water outlet tank. The flexible aluminum air battery comprises carbon positive electrode coating, hydrophilic filter membrane substrate and aluminum negative electrode coating. The hydrophilic filter membrane matrix is separation material. The carbon positive electrode coating is positive electrode. The aluminum negative electrode coating is negative electrode. The carbon positive electrode coating and aluminum negative electrode coating are connected with electric appliance through current collector. The waste water flows into water inlet tank through conduit driven by water pump and flows out of water outlet tank through conduit after passing through filter cavity. USE - Self powered heavy metal recovery device based on flexible aluminum air battery is used for water treatment. ADVANTAGE - The device has high-quality resource utilization of aluminum solid waste resources and heavy metal ions in the process of wastewater self purification, so as to achieve the purpose of treating waste with waste and generating electric energy and nano devices. DESCRIPTION OF DRAWING(S) - The drawing shows a structure schematic diagram of self powered heavy metal recovery device based on flexible aluminum air battery. 2Aluminum negative electrode coating 3Hydrophilic filter membrane substrate 5Current collector
