Drying Technology
The sludge of sewage treatment plant is mainly composed of primary sedimentation tank (grit chamber) and bottom sludge of oil separation tank, scum of air flotation machine, residual activated sludge and chemical sludge of other process units.
Sludge is the sediment produced by the removal of solid substances in the solution by different separation methods during the treatment of industrial wastewater and urban sewage in sewage treatment plants. According to different sources, sludge can be div
With the growth of the national economy and the continuous advancement of urbanization, the discharge of municipal sludge and industrial sludge has increased year by year.
Due to the high moisture content and huge volume of sludge, it is inconvenient to store and transport. Improper treatment will cause secondary pollution to the environment. The belt dryer has the advantages of low energy consumption,
With the acceleration of urban construction in my country, the output of urban sludge is increasing. As the world grows, proper disposal of sludge has become an urgent task.
Sludge drying technology is increasingly popularized internationally and has become an important method for sludge disposal.
There are many ways to deal with the sludge problems.
Sludge treatment is the process of thickening, conditioning, dewatering, stabilizing, drying or incineration of sludge
