The invention relates to a sewage purification device, which comprises a floating body, a light-gathering part, a light guide body and a film-hanging filler, wherein the floating body is arranged in a light-transmitting manner, the light-gathering part is arranged at the upper part of the floating body, the light guide body is arranged at the lower part of the floating body, the light-gathering part is arranged corresponding to the light guide body so as to guide collected sunlight into the light guide body, and the film-hanging filler is arranged at the lower part of the floating body and is positioned outside. By adopting the technical scheme, the invention provides the sewage purification device, the floating body floats on the water surface, the light-focusing component is positioned outside the water surface, the light guide body and the biofilm culturing filler are positioned under the water, microorganisms such as photosynthetic bacteria, algae and nitrifying bacteria in the sewage form a biofilm on the biofilm culturing filler, organic matters in the sewage can be decomposed, and the light-focusing component collects sunlight and guides the sunlight into the light guide body, so that the photosynthesis condition of the photosynthetic bacteria in the sewage is improved, the illumination intensity in the sewage is improved, the photosynthesis of the biofilm on the biofilm culturing filler is enhanced, and the capability of removing the organic matters, nitrogen and phosphorus is enhanced. |
