Hybrid dynamic control of a sewage sludge dewatering and incineration process

As a result of the spread of sewerage systems, the management of growing quantities of sewage sludge is becoming an urgent need. As the method of sludge management, thermal processes have mostly been applied to the treatment and disposal of sewage sludge in Japan, because of the difficulty of finding final disposal sites. This paper describes the progress of thermal processing technologies, especially focusing on drying-incineration process systems and melting-slag recycling process systems.

Abatement Strategy

Sludge agriculture application in future will be one of the main sewage sludge disposal ways in China. To ensure safety and environment of sewage sludge agriculture application, except to strengthen the research of sludge heavy metal, pathogen outside the organic contaminants will be one of the focuses of the future research, especially to strengthen the PAHs and NP/NPE. In order to reduce the environmental risks of sludge agriculture application, using biological aerobic fermentation processing technology treatment sludge can effectively reduce the organic contaminants, depress secondary pollution problem, which sewage sludge brings.
