In mud, organic principle once occurs putrid and deteriorated environment to cause serious secondary pollution；(3) useful resources in mud is not
It is obtained by, brings the waste of resource, do not meet the target of sustainable development.
World Water environmental organization in order to reflect that most town sewage plant mud has the value of re-using accurately,
Being renamed as " biosolids " by sewage plant sludge, its precise meaning is: " a kind of can effectively utilize, rich in organic city
Pollutant ".Along with sewage network construction, the drain pollution management standardization, the harmful substance in town sewage plant mud (is limited to its agriculture
With, the toxic organic compound of woods, heavy metal) gradually decrease, therefore, sludge landfill characteristics resource (woods fertile, agriculture fertile) utilizes should
This is the final purpose of sludge treatment.But traditional sludge composting method (aerobic, anaerobism, two-phased digestion) exists and takes up an area big, need
Want time length, the innoxious shortcoming such as the most thorough.
