Background
Along with the development of industrial production and the continuous promotion of urbanization in China, the treatment capacity of municipal sewage and industrial wastewater is continuously improved, and the sludge amount generated by sewage treatment is also greatly increased. According to the industrial experience, about 6-7 tons of sludge is generated by 1 ten thousand tons of urban domestic sewage, and about 10-30 tons of sludge is generated by 1 ten thousand tons of industrial wastewater. According to incomplete statistics, the sludge which is safely treated and disposed in China at present is less than 20%, so that a large amount of sludge is accumulated, a large amount of land is occupied, environmental pollution is caused, and resources are wasted. Therefore, the realization of stabilization, reduction, harmlessness and reclamation of the sludge is a problem which is urgently needed to be solved at present in China.
Common disposal methods of sludge include methods such as landfill, fertilizer preparation, drying and the like, and because the sludge drying can effectively kill pathogenic bacteria, the sludge volume can be obviously reduced, and meanwhile, odor is eliminated, so that the sludge is paid much attention. The sludge heat drying is that the sludge is directly or indirectly heated by a heat medium through a special process and equipment, so that all or part of water in the sludge is evaporated.
As a common sludge treatment method, the sludge drying technology is widely applied to western developed countries in the beginning of the 80 th 20 th century, China draws the successful experience of the western developed countries, and the sludge drying technology is introduced into domestic sludge treatment. Although more sludge drying researches and applications are performed at home and abroad, a plurality of defects still exist:
(1) at present, heat sources adopted by a sludge drying system mainly comprise flue gas, hot dry gas, hot coal, methane, steam, fuel oil, natural gas and the like, and little research on sludge drying is carried out by taking new energy as a heat source;
(2) the sludge heat drying is to remove moisture in the sludge through the heat transfer effect between the sludge and a heating medium, and the energy consumption of the sludge drying is higher due to the lower heat transfer efficiency of the drying equipment;
(3) because the sludge can generate sewage and odor in the drying process, the sludge needs to be properly treated, thereby increasing the operating cost;
(4) the sludge of the sewage plant is still high in water content after being concentrated, is blocky in the drying process and cannot be uniformly heated;
(5) at the present stage, town and industrial sewage are all sent to a sewage treatment station for treatment, organic matters in the sewage cannot be well utilized, and resource waste is caused.
