Abstract

The invention provides a rapid sludge granulation and drying treatment system and method based on medium loading, and belongs to the technical field of sludge treatment. The system comprises a sludgedewatering device, a heat transfer medium heating device, a granulator, a sludge dryer, a rolling crushing device and a screening device which are connected in sequence. A plurality of metal balls areheated in the heat transfer medium heating device and sent into a granulator, and sludge is dewatered and sent into the granulator; the metal balls are mixed with wet sludge to form homogenized sludge balls with the ball centers being the metal balls and the outer surfaces being wrapped with the wet sludge, then the homogenized sludge balls enter the sludge drying machine to remove moisture in the sludge, the sludge is ground through grinding, the metal balls and the sludge are separated, and after screening is conducted through the screening machine, the metal balls are repeatedly heated andrecycled, and the dried sludge is conveyed to a dry material bin. The system has the advantages that heat is provided by the metal balls in the sludge balls so that sludge is internally and externally heated, the energy consumption of sludge drying is greatly reduced, the moisture content of the sludge is further reduced, and the sludge drying efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of sludge treatment, and in particular relates to a rapid sludge granulation and drying treatment system and treatment method based on medium loading. Background technique [0002] All water supply treatment plants and sewage treatment plants are faced with the problem of how to dispose of a large amount of surplus sludge produced every day. At present, the water content of a large amount of excess sludge produced by water supply plants and sewage plants is generally as high as 99%. Sludge dewatering equipment is often used to dehydrate the sludge to reduce the water content of the sludge to 60-80%. , occupying a large space. With the promulgation of the Law on the Prevention and Control of Environmental Pollution by Solid Waste (revised in 2020), more stringent requirements are put forward for the treatment and disposal of industrial waste, including water supply and sewage sludge, to further reduce the mo...
