Abstract:
This paper emphatically probes into main microorganism groups and their characteristics in sewage sludge aeration composition system,and relationships between these groups and the environmental factors.Researches show that there exist interactions between microorganism groups and the environmental factors,such as organic matters,temperature and pH.Organic matters and temperature are two primary factors that effect on variations of microorganism groups. pH is a non-primary environmental factor.It is also found that microbial quantity variation curve in sludge composting process is different from that of in wastewater treatment process.
