Analysis on the change factors of organic matter in sludge heat treatment process

In the steady development of social economy, the urbanization process is getting faster and faster, the discharge of urban domestic sewage continues to rise. Sludge, as a solid waste produced during sewage treatment, will generally produce 1.5 to 2.0 tons of sludge per 10,000 tons of sewage. As the sludge directly affects the quality and environment of the city and the application efficiency of resources, how to properly dispose of the sludge is the main problem of scientific research. In this paper, based on the understanding of sludge heat treatment process and research status, according to the change of organic components in the analysis, the underlying law is deeply discussed. The final experimental results show that the sludge hydrolysate can violate the nitrification system and provide carbon sources.
