Description

Technical Field

[0001] The utility model relates to the technical field of separation devices, in particular to a device for separating sand and fiber in sludge. Background Art

[0002] Sludge refers to the solid waste produced in the process of water treatment, wastewater treatment and sewage treatment. It is composed of a mixture of suspended matter, sediment and microorganisms in water. Sludge usually contains organic matter, inorganic matter, microorganisms, heavy metals and other components. Sludge sand and fiber are different components of sludge produced in the sewage treatment process.

[0003] Sludge, sand and gravel mainly refer to the sediment and suspended matter in sewage treatment, including solid particles such as sand, gravel, and silt. These particles are large and heavy, and are usually separated and removed by physical treatment methods such as sedimentation tanks or grit chambers. The treated sludge, sand and gravel can be used as landfill materials or in the production of building materials. Fiber refers to organic fiber substances in the sewage treatment process, which usually come from the degradation of organic matter such as paper and cellulose. These fiber substances can be degraded and decomposed by bioreactors or aerobic digesters in biological treatment methods. The treated fibers can be further used in the production of biomass energy, such as fermentation to produce biogas. Sludge, sand and gravel and fibers are solid wastes generated in the sewage treatment process. Their reasonable treatment and utilization can reduce pollution to the environment and achieve resource recovery and energy utilization.
