Problems solved by technology

[0004] However, the above-mentioned treatment process has the following technical defects: 1) The heat transfer evaporation drying process consumes a lot of heat and energy consumption, and the sludge will emit a large amount of malodorous gas during the heating process; 2) The conventional mechanical dehydration and drying process requires Add a large amount of additives, the cost is high, the effect of dehydration and drying is not obvious, and the sludge may be converted into chemical sludge during the treatment process, which limits the subsequent disposal; 3) The anaerobic fermentation treatment process is affected by the change of sludge composition 4) The energy consumption of aerobic fermentation

Abstract

The invention discloses a sludge treatment process which comprises the following steps: (1) sterilizing sludge so as to kill microorganisms in the sludge; (2) dewatering and drying the sterilized sludge so as to reduce the water content of the sludge; (3) separating the dried sludge, carrying out high temperature plasma treatment on the separated sludge, and burning separated smoke; (4) carrying out sludge-smoke separation on smoke generated by reburning treatment, carrying out high temperature plasma treatment on the separated sludge again, and purifying and cooling the separated smoke. The invention further discloses a sludge treatment system capable of carrying out the sludge treatment process. The sludge treatment system comprises a sterilizing device, a dewatering device, a drying device, a plasma gasifying or plasma vitrifying device and a purifying device. The sludge treatment system can realize harmless, reducing and resourceful treatment for the sludge and does not generate secondary pollution, is safe and reliable, and can realize thorough treatment for the sludge.

Description

technical field [0001] The present invention relates to a sludge treatment system, in particular to a sludge treatment process using high-temperature plasma gasification technology for harmless treatment of sludge. The treatment system is suitable for the treatment of muddy solid waste such as municipal sludge and industrial sludge, and belongs to the field of environmental protection. Background technique [0002] Sludge is a product in the sewage treatment process, which has complex components, colloidal shape, unstable properties, perishable odor, high content of heavy metals, toxic and harmful pollutants, high moisture content, poor dehydration, not easy to dehydrate, and contains a large number of pathogenic bacteria and characteristics of parasite eggs. If this kind of sludge is not properly treated, it will cause great harm to the environment, human and animal health. [0003] At present, the sludge treatment process mainly includes two categories: sludge drying tre...
