Description

Technical Field

[0001] The utility model relates to the technical field of solid waste separation, in particular to a solid waste separation device for urban domestic sewage. Background Art

[0002] Urban domestic sewage contains a large amount of suspended solids, chemically or biologically degradable soluble or colloidally dispersed organic matter, nitrogen-containing compounds, phosphates, potassium, sodium and heavy metal ions, fungal biota, etc. If it is discharged into natural water bodies without treatment or with insufficient treatment, it will cause eutrophication and toxic accumulation of water bodies, leading to the deterioration of the ecological environment; toxic substances in water bodies enter the food chain through aquatic animals, and ultimately endanger human health. Sewage, as a second water source, can alleviate the problem of water resource tension. As the global water resource crisis is threatening human survival and development, many countries and regions in the world have made overall plans for sewage treatment and reuse, and regard treated recycled sewage as a new water source to alleviate the problem of water resource tension. The reuse of sewage after proper treatment can promote the benign circulation of water in nature. Urban sewage is available nearby and easy to collect and transmit. The water quality and quantity are stable and reliable, and the treatment is simple and easy. As a second water source, it is much more reliable than rainwater and seawater.

[0003] Most of the solid waste separation devices for urban domestic sewage on the market do not have a structure for squeezing the waste during waste separation, which results in that the liquid inside the waste cannot be completely separated out, affecting the separation effect and quality of the device.
