Abstract

The invention discloses a sludge viscosity characterization method, which comprises a sludge pretreatment process, a sludge viscosity test process and a sludge viscosity characterization device, and the sludge viscosity test process specifically comprises the following steps: installing an angle adjusting jack; measuring a sludge sliding angle; the invention provides a sludge characterization method which is used for characterizing adhesion conditions of different types of sludge to the surface, a shaft and the like of mechanical equipment in the treatment process, so that corresponding characterization means can be established according to the properties of the sludge in the sludge dynamic treatment processes such as conveying, stirring and extruding of the sludge; therefore, the adhesion degree of the sludge and different container walls is represented, the viscosity strength of the sludge can be conveniently graded through different ranges of the sludge sliding angle, so that people can conveniently and better know the viscosity condition in the sludge dynamic treatment process, a new idea is provided for sludge property representation, and the method is suitable for popularization and application. And meanwhile, basic parameters are provided for model selection and design of back-end equipment.

Description

technical field [0001] The invention relates to the technical field of sludge treatment, in particular to a sludge viscosity characterization method. Background technique [0002] Sludge is the product of sewage treatment. Sludge contains organic matter, heavy metals, pathogenic bacteria and other components. Its physical and chemical properties are very unstable. During the process of storage, transportation and treatment, the properties of its components will continue to change. If treated Improper disposal will cause serious harm to the environment. With the continuous and rapid development of my country's economy, the scale of urban sewage treatment in my country is increasing day by day, and the sludge production has also increased accordingly. According to statistics, my country's sludge production in 2019 has exceeded 60 million tons (in terms of water content rate of 80%), it is estimated that my country's annual sludge output will exceed 90 million tons in 2025. Howev...
