How to treat sludge? What method is used for municipal sludge treatment?

With the increase of urban population, industrialization and urban sewage treatment plants, the amount of sludge has gradually increased, and sludge treatment has become the focus of environmental concern. The original technology, including drying, landfill, composting and other processes, is only a simple treatment of sludge! How to achieve "reduction", "harmlessness" and "resource" in sludge treatment has now become the focus of many enterprises!

Sludge carbonization technology is a process of "dry-sliding" sludge in a carbonization machine under oxygen-free or micro-oxygen conditions, which makes the water in the sludge evaporate and effectively retains the carbon value in the sludge. The organic matter in sludge is carbonized, and the properties of carbonized sludge are similar to those of activated carbon, which can be widely used for adsorption, deodorization and dehydration. Moreover, the volume of carbonized sludge is small, and there is no toxic gas in the sludge, which will not cause secondary pollution. Therefore, sludge carbonization is an economical treatment technology that can not only destroy the environment but also recycle resources. Sludge carbonization technology can not only effectively treat sludge, but also make it into high value-added activated carbon to realize the resource disposal of waste!
