Abstract

The production and concentration change of ammonia in aerobic compost of municipal solid waste were studied for four weeks. The ammonia was produced by amination action of microbe. The maximal concentrations of water soluble ammonia and gaseous ammonia come forth during the period of high temperature of the composting in the former two weeks. Volatilization of ammonia is the maximal loss of water soluble nitrogen during composting, but the gaseous ammonia concentration was affected by change of water-soluble ammonia concentration and temperature. The water soluble ammonia concentration also affected total nitrogen concentration. However, their concentrations were almost equal during high temperature period because of no function of nitration bacterium.
