Description

Technical Field

[0001] The utility model relates to the technical field of sludge processing equipment, in particular to a sludge metal extraction device. Background Art

[0002] Sludge is a solid precipitate produced by the water and sewage treatment process. Generally, the sludge produced by sewage treatment plants and garbage disposal centers contains more or less metals. Metals exist in sludge in two forms: one is the free state of ions, and the other is the solid state in the form of metal elements, alloys and other compounds. The second form of existence can be further divided into large lumps (diameter greater than 5cm), small lumps (diameter between 1 and 5cm), and microparticles (diameter less than 1cm). For small lumps and microparticles in sludge, the number of metal solids is large and the mass is small, making it difficult to separate them.

[0003] Therefore, solid metal particles in sludge are almost never recycled. The metal particles are eventually landfilled with the sludge, resulting in a waste of resources. At the same time, the metals contained in the sludge may form ions again and then penetrate into the groundwater and nearby land, causing great harm to the environment and affecting the health of nearby residents.
