NOVELTY - Processing of stock raising waste material (1,2) involves methane fermentation process (3) which ferments the waste material and forms methane. Methane is then recovered from the waste material and subjected to desulfurization (4), and ammonia (14) is collected from the waste material by ammonia collection process (11).    USE - For processing stock raising waste material such as livestock excrement and livestock urine.    ADVANTAGE - Concentration of ammonia in the fertilizer produced from the waste material is reduced, by carrying out ammoniation of the waste material after methane fermentation process. Ammonia recovered can be effectively used as a resource. The solid-liquid separation performed in the waste water treatment installation reduces load of a biological treatment process. Also, the capacity and operating cost of the biological treatment apparatus is reduced. Since ammonia collection is performed at a boiling temperature, sterilization of a microorganism occurs. Since a portion of solid-liquid mixture from ammonia collection process is circulated to methane fermentation process, heat recovery is possible by carrying out heating of methane fermentation process at 30-55 degrees C and ammonia is additionally produced. Thus the amount of ammonia collected in the ammonia collection process is increased. An ammonia obstruction at the methane fermentation process is inhibited. Ammonia concentration in methane fermentation process is maintained low by reducing ammonia concentration in the methane fermentation process inlet.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for stock raising waste treatment equipment comprising a methane fermentation apparatus for producing methane from the waste material, a methane de-sulfurizing apparatus for removing sulfur content from the methane produced, and an ammonia collection equipment. The ammonia collection equipment collects ammonia from the waste material before or after methane fermentation.
