A reduction treatment apparatus can include a reduction furnace configured to reduce zinc andor iron oxide through heat treatment of zinc-containing iron oxide or zinc oxide or iron oxide, with a reducing material. Thus, the control screw is unscrewed from the screw bore of the pan body to connect the grease draining pipe to the screw bore of the pan body, so that the grease in the receiving chamber of the pan body in turn flows through the screw bore of the pan body into the grease draining pipe and is drained outwardly from the grease draining pipe. A dual conversion gain element is coupled between each floating diffusion node and a respective capacitor. The embodiments of the disclosure are used in the design of controlling the PLC apparatus. The kinetic energy of the water jet is transmitted to the electric generator for producing electricity through the power transmission system.
