Directed at the current situation of the prior art and based on a circulating water flushing type ecological toilet, the invention aims to realize self-circulation, no emission, no picking and complete decomposition of water flushing type toilets. Through a current reactor and by the mode of anaerobiosis, anoxia, aerobiosis, anoxia, and anaerobiosis, a biological rotating disc is designed into a facultative pond with a special structure. A wood fiber bio-carrier bed is employed, and an ultrasound technology is adopted to perform a new internal circulation stirring process in the biological rotating disc facultative pond, an upflow type anaerobic tank, and an anoxic tank so as to accelerate decomposition and digestion of organic matters. Meanwhile, electro-adsorption, high-energy physics, an anaerobic and aerobic wood fiber integrated facultative tank and other technologies are adopted to conduct water treatment on fecal sewage. The invention can achieve through and complete decomposition of organic matters and eliminate malodor. The bio-environmental protection toilet needs no water supply, and the first supplied water can be circulated for use, so that no more water needs to be added. The toilet provided in the invention is an environmental protection toilet having no residue, precipitate, emission or pollutant.
