Sludge is a product of sewage treatment and is an extremely complex heterogeneous body composed of organic residues, bacterial cells, inorganic particles, colloids and the like. The main characteristics of the sludge are high water content (up to 99%), high content of organic matter, easy to decay and stink, fine particles, small specific gravity and colloidal liquid. With the promotion and development of wastewater treatment technology, the amount of sludge generated is increasing, and the types and properties are more complicated. The toxic and harmful substances in the wastewater are often concentrated in the sludge, so the sludge is one of the serious factors affecting the environment. However, if the sludge is properly treated, it will become a renewable resource and be used for soil fertilizer, fuel and so on. The testing of sludge is of great significance for guiding the sludge treatment.
