NOVELTY - A sewage processing device for circulating biological bacterium system reduction, has waste receiver (1) connected with chamber pot, fungi bed storage device assembly (2) connected with biological reduction processing box (3) which is connected with the cleaning water storage tank (4) by pipeline. The overflow outlet (5), through which processed sewage can overflow. The biological bacteria such as paramecium and ciliate, Epistylis and Opercularia are placed in the storage device assembly.    USE - The sewage processing device is useful for circulating biological bacterium system reduction (claimed).    ADVANTAGE - The process is carried out in simple method.    DETAILED DESCRIPTION - An economizing type sewage processing device for circulating biological bacterium system reduction, has waste receiver (1) connected with chamber pot, fungi bed storage device assembly (2) connected with pipeline. The fungi bed-biological membrane of paramecium and ciliate is placed at the frontal 1/3 portion of the fungi bed storage device assembly. The fungi bed-biological membrane of Epistylis is placed at the middle 1/3 portion of the fungi bed storage device assembly. The fungi bed-biological membrane of Opercularia is placed at the back 1/3 portion of the fungi bed storage device assembly. There is overflow outlet (5), through which processed sewage can overflow to the next portion, at the upper side of every portion. The fungi bed storage device assembly is connected with biological reduction processing box (3) by pipeline. There is carbon treatment adsorption bag in the biological reduction processing box. The biological reduction processing box is connected with the cleaning water storage tank (4) by pipeline and vent hole connected with exhaust pipe. There is timing circulation sewage pump between microorganisms to periodically pump untreated solids for repeated treatment. The clean water in the cleaning water storage tank is pumped by pump into the flushing tank to be recycled. Biological bacteria are attached on the dynamic fungi bed-biological membranes to process and clean sediments and reduce them into mixed water by nibbling method with the help of flowing or pump circulation. The mixed water is further cleaned by biological bacteria and carbon absorption. The de-colored, cleaned and deodorized water enters the cleaning water tank to be recycled.
