Description

Sludge treatment system
Technical Field
The invention belongs to the field of organic solid waste treatment, and particularly relates to a sludge treatment system.
Background
Sludge is a byproduct produced in the process of treating urban domestic sewage and industrial wastewater. In recent years, the municipal sewage treatment industry has been rapidly developed, and biological treatment techniques are being widely used, resulting in a great increase in sludge production. On the other hand, the sludge has the characteristics of high water content, easy decay and strong odor, and contains substances such as parasitic ova, pathogenic microorganisms, heavy metals and the like. The random discharge of the substances can cause secondary pollution to the environment, and the effective treatment and disposal of the sludge are seriously restricted. At present, the sludge disposal modes comprise sanitary landfill, ocean dumping, incineration and the like, and the sanitary landfill has the advantages of low investment, quick effect, large capacity and the like, and is the sludge disposal mode mainly adopted in China at present. However, the sludge landfill area is large, and the landfill leachate has a large amount of heavy metals and refractory organic matters, so that soil and underground water are easily polluted. Furthermore, the sludge in the landfill site is subjected to anaerobic fermentation to generate a large amount of methane, and if measures are not taken properly, explosion and fire are likely to occur. On this basis, the sanitary landfill treatment of sludge is subject to great use restrictions.
One solution to the above problem is to treat the sludge by thermochemical conversion techniques. After heat treatment, the conversion rate of organic matters in the sludge reaches over 90 percent, and the volume is reduced by over 80 percent. But the relevant studies were all carried out in batch reactors. The intermittent operation has the problems of complex operation caused by repeated disassembly of the device, high energy consumption caused by repeated heating and cooling, limited daily treatment capacity and the like, and greatly limits the further popularization and application of the thermochemical conversion of the sludge. To further generalize the use of sludge thermochemical conversion technology, continuous plants need to be developed. At present, researches on a sludge thermochemical conversion reaction device are few, and no scheme is provided for better realizing the thermochemical conversion of the sludge.
