Drying Technology
It's necessary to properly treat and dispose the sludge to avoid secondary pollution and meet the requirements for reduction, stabilization and harmlessness of sludge treatment and disposal.
With the development of urbanization and social economy, the total annual sludge production in China continues to rise. As of January 2020, there are 10113 sewage treatment plants in China.
Sludge drying processes are mainly divided into mechanical press drying and heating drying drying. The mechanical press drying processes include ordinary mechanical press drying and mechanical filter pressing drying
Sludge characteristics are also related to drainage system, living habits, natural climate and treatment process.
The output of sludgein China is increasing year by year, and the risk of impact on the environment is extremely high. With the continuous progress and improvement of sludge drying technology, my country will also widely use sludge drying technology dispos
At present, the vast majority of domestic sewage flowing into urban sewage treatment plants has very complex industrial wastewater components, and the toxic and harmful substances in the wastewater body will permeate into the sludge.
As people's requirements for environmental management and environmental protection are increasing, the harmlessness, reduction and resource disposal of sludge in sewage treatment plants are getting more and more attention. The incineration of sludge in
Fecal sludge is different to wastewater and cannot simply be co-treated at sewage treatment plants. Small additions of fecal sludge are possible if plants are underutilized and able to take the additional load
The choice of a sludge treatment method depends on the volume of sludge generated, and comparison of treatment costs required for available disposal options.
