The invention provides an artificial
wetland system for treating rural domestic
sewage. The
system comprises a
microbial fuel cell wetland module, which sequentially comprises an impermeable bottom layer, a
sewage distribution layer, an
anode layer, an insulating filler layer, a gas distribution layer, a
cathode layer and a planting matrix layer from bottom to top, wherein the
anode layer comprises an upper layer, a sandwich layer and a lower layer, the upper layer and the lower layer are plate-shaped
anode materials with meshes, the upper layer is electrically connected with the lower layer,the sandwich layer is an active
microorganism layer, and is filled between the upper layer and the lower layer, the
cathode layer comprises a plate-shaped material with meshes, gas distributed in thegas distribution layer contains
oxygen, and the anode layer and the
cathode layer are connected with an
external circuit through conduction wires to form a
closed circuit. The artificial
wetland system for treating rural domestic
sewage has the advantages of high removal rate of organic matters,
nitrogen and
phosphorus in domestic sewage, high conversion rate of
electric energy and low construction cost.
