<p><P>PROBLEM TO BE SOLVED: To provide a method for treating livestock farm sewage discharged from livestock farms without deteriorating the surrounding environment and producing a feeling of repulsion in neighbors by deodorizing and purifying the livestock farm sewage using no medicines nor disinfectants that contain a large amount of chemical substances. <P>SOLUTION: A livestock farm sewage 15 discharged from livestock farms is deodorized and purified with a two-species-mixed lactobacillus in which Lactobacillus fermentum and Enterococcus faecium are mixed to produce treated water 22 whose BOD is 50 to 200 ppm. The treated water 22 is introduced into an evaporation tank 31 packed with scrap pieces of wood 30 like wood shavings or sawdust for evaporation treatment wherein the treated water 22 is evaporated into the atmosphere. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
