Problems solved by technology
Li Haitao et al. (2013) studied the anaerobic baffle reactor in anaerobic digestion and treatment of petrochemical residual sludge. The research found that the system was unstable, and the biotransformation efficiency was low, and it could not effectively remove organic pollutants.
[0005] In summary, these limiting factors have seriously affected the reduction, harmlessness and resource utilization of municipal sludge

The invention relates to the technical field of environmental engineering, in particular to a municipal sludge high-efficiency anaerobic biological transformation device and a transformation method thereof. The transformation device comprises a hydrothermal pretreatment tank, a preheating heat exchanger, a cooling adjustment tank, an anaerobic reactor and a sludge sedimentation tank, wherein the hydrothermal pretreatment tank is used for heating part of the original sludge in advance, a heating device is arranged at the bottom of the hydrothermal pretreatment tank, and a preheating stirring device is arranged in the hydrothermal pretreatment tank; the preheating heat exchanger is used for receiving sludge which is heated by the hydrothermal pretreatment tank in advance, and the rest of thecooled sludge is subjected to pre-heating through the sludge pre-heated in advance. The anaerobic reactor comprises a tank body; and a biological membrane component, a jet flow water distribution device and a jet flow stirring device are arranged in the tank body. According to the method disclosed by the invention, the reduction of municipal sludge is realized, and the pollutants in the sludge are removed, the clean biogas is obtained at the same time, the process flow is simple, the operation cost is low, and the method has a large application value.
Description
technical field [0001] The invention relates to the technical field of environmental engineering, in particular to a municipal sludge high-efficiency anaerobic biological conversion device and a conversion method thereof, belonging to municipal sludge sludge reduction, resource utilization and harmless technologies. Background technique [0002] The residual sludge produced by municipal sewage treatment plants contains a large amount of available components such as nitrogen, phosphorus, various trace elements and organic matter, and also contains toxic, harmful, refractory organic matter, pathogenic bacteria, parasites (eggs) and heavy metals, etc., and often Accompanied by stench, improper disposal will cause great harm to the ecological environment and human beings. Therefore, it is of great significance to explore and seek economical and effective sludge disposal technology suitable for my country's national conditions. [0003] Anaerobic digestion has the advantages of ef...
