Abstract

The invention discloses a synchronous electricity generation and sewage purification device utilizing steel slag as a positive electrode. The steel slag utilized as positive electrode filler for a battery is embedded into a vertical flow artificial wetland system, so that a novel structure method with a microbial fuel cell and a constructed wetland which are coupled is formed. A bottom non-conductive filler layer, a steel slag positive electrode layer, a current collector inserted into the steel slag positive electrode layer, a top non-conductive filler layer, wetland plants planted in the non-conductive filler layers and a top negative electrode layer are laid on the system from bottom to top, wherein the negative electrode layer and the positive electrode layer are respectively connected with a resistor box through wires so as to form a closed loop. The steel slag electrode is embedded into a positive electrode of the microbial fuel cell and meanwhile coupled with the vertical current constructed wetland, so that dual effects of synchronous electricity generation and sewage purification are realized, the positive electrode teleportation efficiency is improved, the internal resistance of the battery is reduced, the electricity generation performance is improved, and meanwhile the water acidification problem is solved.

Description

technical field [0001] The invention belongs to the field of sewage treatment, and in particular relates to a device for synchronous electricity production and sewage purification using steel slag as an anode, which realizes electricity production and sewage purification by coupling a vertical flow constructed wetland with a microbial fuel cell. Background technique [0002] The energy crisis and environmental pollution, as well as the resulting social and climate problems, have become the focus of attention all over the world. The development of clean energy and circular economy based on the principle of "reduction, recycling and reuse" is an important way to build a resource-saving and environment-friendly society and achieve sustainable development. The development and utilization of clean energy such as solar energy, nuclear energy, wind energy, and biomass energy is an inevitable choice to replace traditional energy and solve the energy crisis, and it is also a strategi...
