Abstract

The invention provides a household waste hydro-separation and pulping technology and a treatment system. The treatment system comprises a hydro-separation system, a pulping system and a fermentation system. The hydro-separation system comprises a separation tank, a water spraying device, a first separation grid, a switching plate and a discharging squeezing threaded rod, wherein the water spraying device is arranged in the separation tank, the first separation grid is used for conveying light materials, the switching plate is arranged at the bottom of the first separation grid, and the discharging squeezing threaded rod is arranged at the top of the first separation grid and used for conveying inorganic matter. The hydro-separation system further comprises a sedimentation basin, a discharging long threaded rod, a second separation grid and a water drainage exit, wherein the discharging long threaded rod is arranged at the bottom of the sedimentation basin, the second separation grid is used for conveying organic matter, and the water drainage exit is formed in the bottom of the sedimentation basin. The pulping system comprises a hammer type pulping machine for pulping and a rotational flow sand removing device for removing sand. An eluting device arranged on the upper portion of the first separation grid is further included. According to the design, the organic matter and the inorganic matter in urban household waste can be separated effectively, the separated-out organic matter is subjected to smashing and sand removing, grid connection is conducted on fermented biogas, and biogas slurry is recycled, so that the waste resource recovery level is improved greatly.

Description

[technical field] [0001] The invention relates to the technical field of urban domestic waste treatment, in particular to a domestic waste hydraulic separation and pulping process that can fully meet the waste treatment needs of various cities, has strong adaptability, and can greatly reduce the pollution generated by domestic waste and processing systems. [Background technique] [0002] With the rapid development of my country's economy and the continuous expansion of urbanization, the total amount of urban domestic waste in my country is also increasing. At present, most of the main garbage disposal in our country adopts sanitary landfill, incineration technology treatment and simple composting. The sanitary landfill method has low investment and simple operation, but it occupies a large amount of land and the resource recovery rate is low. The landfill leachate generated in the later stage needs to be treated for a long time, and the management period is long. Incinerat...
