Sludge biological landfill type dehydration treatment system

Abstract

The invention discloses a biological landfill type dehydration treatment system for sludge. The system comprises a primary filtering unit, a two-stage filtering unit and a mixed material drying oven which are connected in sequence, wherein the two-stage filtering unit comprises a barrel and a jacket; sludge is contained in the barrel; a first filtering hole and a second filtering hole are formed in the side walls of the two opposite sides of the barrel respectively; the aperture of the first filter hole is greater than that of the second filter hole; the jacket is in circumferential sliding fit with the side wall of the barrel; the jacket comprises a first baffle and a second baffle which are connected with each other; the first baffle is attached to the outer wall of the barrel; the second baffle is attached to the inner wall of the barrel; a liquid collecting tank is arranged on the periphery of the barrel; the clamping sleeve is driven to switch positions between the first filter hole and the second filter hole, so that a drainage path of sludge in the barrel is changed; and the first baffle and the second baffle are also oppositely provided with groove structures, and the filter hole structures are reversely scoured by utilizing external water flow, so that the long-time non-blocking stable operation of the equipment is realized.

Description

technical field [0001] The invention relates to the field of sludge treatment, in particular to a sludge biological landfill dehydration treatment system. Background technique [0002] Sludge is a solid waste produced by sewage plant wastewater. Its composition is complex, including refractory organic matter, inorganic matter, heavy metal components, and microbial parasites. At present, domestic sludge treatment mainly adopts incineration, agricultural use, landfill and making building materials, among which landfill is still the most important treatment method. Traditional landfills occupy a large area, and this shortcoming becomes more and more obvious with the accumulation of time. Therefore, in order to realize the resource reuse of sludge and use the landfill environment to degrade components to realize site recycling, it is necessary to invent a sludge bio-landfill dehydration treatment system with functions of water removal, drying and mixing.
