NOVELTY - A heavy metal sewage processing device comprises a mixing tank (1) and a connecting water pipe (3) that are connected with mixing tank (2). The mixing tank is provided with lower part of upper inlet (4), where inlet opening far away from the connecting water pipe is provided with transporting pipe (5). The mixing tank is set with a stirrer (6). A separation tank is provided and is divided into storing area (7) and settling zone (8). A baffle (9) is provided with a microfiltration membrane (10).    USE - Device used for processing heavy metal and sewage.    ADVANTAGE - The device can obtain heavy metal through recovering (especially noble metal) to reduce the secondary pollution, reduce the resource waste, and reduce the heavy metal polluted water, and thus reducing the heat treatment cost.    DETAILED DESCRIPTION - A heavy metal sewage processing device comprises a mixing tank (1) and a connecting water pipe (3) that are connected with mixing tank (2). The mixing tank is provided with lower part of upper inlet (4), where inlet opening far away from the connecting water pipe is provided with transporting pipe (5). The mixing tank is set with a stirrer (6). A separation tank (2) is provided and is divided into storing area (7) and settling zone (8). A baffle (9) is provided with a microfiltration membrane (10). The settling zone (8) near to the connecting water pipe is provided with a spiral adding flocculating agent device (11) at the bottom. The separation tank via the first valve is connected with a pipeline. The pipeline and the settling zone are connected. The separation tank is provided with the storing area that is connected to the pipe flow area.
