Embodiment 1

[0027] Embodiment 1: a kind of domestic waste multi-stage recovery processing method, comprises the following steps:

[0028] S1: First-level magnetic separation: transport the domestic waste to be processed to the sorting pool for a sorting, and use the magnetic force to sort out the metal waste, and collect and store the metal waste to the magnetized sorting port;

[0029] S2: First-level shredding: pump the garbage from S1 to the coarse garbage shredder for the first garbage shredding, control the speed of the knife roller of the garbage shredder at a low speed of 60 rpm, high torque, and shred the particles The control is about 200mm*500mm*20mm; the cutter roller speed is low speed: 60 rpm, high torque (meaning: low speed and high crushing force), double cutter roller structure, large power, especially for building materials, cars, large garbage The pre-crushing, the crushed material is blocky, large and uneven (approximately: 200mm*500mm*200mm).

Abstract

The invention discloses a multi-stage recycling treatment method for domestic garbage. The multi-stage recycling treatment method comprises the procedures of first-stage magnetic separation, first-stage tearing, second-stage magnetic separation, second-stage tearing, first-stage separation, primary smashing, second-stage separation, garbage separation, third-stage separation, heavy metal separation, secondary smashing, drying, packaging, plastic granulation, and the like. According to the multi-stage recycling treatment method for domestic garbage, the problem that crop growth is affected due to the fact that conventionally, backfilling is mainly adopted as a nuclear garbage treatment means is solved; multi-stage treatment is adopted, the recycling rate is high, and classification, smashing and screening are more thorough; and garbage is finally prepared into organic fertilizer particles, the method is energy-saving and environmentally-friendly, secondary pollution is avoided, and the recycling rate is high.

Description

technical field [0001] The invention relates to the technical field of solid waste treatment, in particular to a multi-stage recovery and treatment method for domestic waste. Background technique [0002] With the acceleration of the life process, the continuous improvement of people's living standards and the change of people's consumption habits, the production of waste as a metabolic product is also increasing day by day. These increasing domestic wastes have seriously disturbed the further development of cities and seriously affected people's lives. At present, the main methods of domestic waste disposal include landfill, incineration for power generation, and classification and recycling. Sorting and recycling is still limited to some solid waste, and has not yet been fully industrialized. Therefore, due to the large amount of waste produced, landfill is currently the most important treatment method. However, this method not only consumes manpower, material and financi...
