Description

technical field [0001] The invention relates to a sludge drying device and system, in particular to an electric heating sludge treatment system. Background technique [0002] Sludge is a kind of viscous substance produced in the process of sewage treatment. It is mainly composed of aerobic and anaerobic microorganisms. Various complex mixtures of organic matter, metals, germs, insect eggs, colloids, etc. on the ground. The composition of sludge varies greatly and varies with the source of sewage, sewage treatment process and season. For large-scale urban sewage treatment plants, due to the large amount of industrial wastewater discharged into the system, the heavy metal content in sewage sludge is relatively high, among which copper and zinc content are often close to or exceed the acceptance standards for sludge as agricultural fertilizers. Sewage from small and medium cities is mainly composed of Domestic sewage is the main source, so there is generally no problem of ex...
