PROBLEM TO BE SOLVED: To activate microorganisms by using a natural enzyme, to decompose organic compounds, nitrogen, or the like, in excreta by the microorganisms to attain decontamination of water and further to assimilate and efficiently treat phosphor which causes eutrophication and which is said to be hardly reduced. SOLUTION: The excreta excreted by cattle or a man is stored in a mixed raw water tank 1, an excreta decomposing treating agent which is obtained by blending bromelain enzyme extracted from pineapple fruit juice with yeast and citric acid water for promoting its catalytic function, is sprinkled in the mixed raw water tank 1 and the microorganisms in the excreta are activated while making the excreta on which the excreta decomposing treating agent is sprinkled overflow a plurality of treating tanks 2, 3, 4, 5, 6, and 7 one by one. Mainly organic materials in the excreta are subjected to decomposing treatment by work of the microorganisms to attain decontamination of the water. COPYRIGHT: (C)2005,JPO&NCIPI
