Sludge is a heterogeneous body composed of organic debris, bacterial bodies, inorganic particles, colloids and the like. It is difficult to perform thorough solid-liquid separation by settling. The sludge produced by sewage treatment is typical organic sludge and has the characteristics of high organic matter content (60-80%), fine particles (0.02-0.2 mm) and small density (1002-1006 Kg/m)³) The sludge is of a colloid structure, is hydrophilic sludge, is easy to convey by a pipeline, and has poor dehydration performance. As the water content of the sludge decreases, the process of the sludge flowing from a pure liquid state to a viscous, plastic, semi-dry solid state to a pure solid state changes. Concentration can reduce the water content to 85% (water-containing state); when the water content is 70-75%, the sludge is in a soft state and is not easy to flow; generally, the water content under dehydration can only be reduced to 60-65%, and the water becomes almost solid at the moment; when the water content is lower than 35-40%, the mixture is in a gathering state (above is in a semi-drying state); further, when the content is as low as 10 to 15%, the powder is formed.

Sludge is an unavoidable byproduct in the sewage treatment process, and generally contains pathogenic microorganisms, parasitic ova, harmful heavy metals and a large amount of difficultly-degradable substances. If the treatment is not thorough, secondary pollution to the environment is easily caused.
