Background

With the rapid development of national economy, the industrialization process of China is also accelerated, but as the industrial structure of China belongs to a rough production mode, the economic development is caused while expensive environmental cost is paid. Especially, the degree of urbanization is continuously improved, the treatment capacity, the treatment rate and the treatment degree of sewage in cities are continuously improved, and the yield of sludge generated by urban sewage treatment is greatly increased, wherein the yield of municipal sludge is increased particularly rapidly. Municipal sludge is an extremely complex heterogeneous body consisting of organic fragments, bacterial bodies, inorganic particles, colloids and the like, and contains a large amount of water, refractory organic matters, heavy metals, salts, pathogen microorganisms, parasitic ova and the like, and the random discharge and stacking of a large amount of untreated sludge can cause more serious secondary pollution to the environment.

At present, municipal sludge is treated by landfill, so that a large amount of precious land resources are occupied, and the sludge contains a large amount of harmful substances, which easily causes secondary pollution to land and underground water resources; on the other hand, the municipal sludge also has certain organic matters and heat value, belongs to a resource capable of being recycled, and is wasted due to the fact that the resource is directly buried.
