Abstract
Sludge is precipitated pollutants generated from the treatment of sewage. The reduction, stabilization, and harmless recycle of sludge have become one of the major social and environmental issues. Low-temperature heat treatment of sludge can take advantage of solar energy, heat pumps, and other renewable thermal energy as well as waste heat from industries. Furthermore, it can reduce the consumption of fossil fuels and the environmental pollution problems caused by high- or middle-temperature sludge treatment process which is above 100 °C. The application of low-temperature sludge heat treatment can not only achieve the reduction and recycle of sludge, but also reduce greenhouse gas emissions in the sludge treatment process which contributes to slow down global warming.
