Description

Technical Field

[0001] The utility model relates to the technical field of solid waste treatment, in particular to a solid waste treatment device for preventing and controlling soil pollution. Background Art

[0002] Soil pollution prevention and control is the process of preventing soil from becoming polluted and improving and treating already contaminated soil. Soil protection should prioritize prevention. Prevention should focus on controlling the concentration and total volume of emissions from various pollution sources; regularly monitoring and supervising agricultural water use to ensure it meets irrigation water quality standards; rationally applying fertilizers and pesticides, and prudently using sewage sludge, river mud, and pond mud; ensuring that urban sewage is purified before irrigation; promoting biological and integrated pest control; and remediating mines to prevent toxic pollution.

[0003] In 2021, the global solid waste treatment market structure showed that organic matter, paper and plastics, metals, and glass accounted for 42%, 25%, and 11%, respectively. Other solid waste types accounted for approximately 22% of the market. This indicates that organic matter is the largest component of solid waste, followed by paper and plastics, with metals and glass also accounting for a significant portion. Therefore, solid waste must be effectively treated before it can be landfilled to avoid soil contamination. Utility Model Content

[0013] Preferably, a dripping pipe is provided at the bottom of the lowest point of the spiral stirring mixer, and an air storage bag is provided at the top of the highest point of the spiral stirring mixer. This ensures that water in the solid waste after mixing with the kitchen waste can be drained away through the dripping pipe, and gases such as methane generated during mixing can also be stored in the air storage bag.

[0014] The utility model proposes a solid waste treatment device for soil pollution prevention and control, which has the beneficial effects of ensuring that the solid waste can be crushed to the maximum extent after double crushing by a coarse crusher and a fine crusher, and then mixed with an organic deoxidizer through a large spray mixing barrel and then mixed with kitchen waste through a spiral stirring mixer, and then using the synergistic anaerobic digestion technology to utilize the complementary effect between different wastes, adjust the nutritional balance, and dilute toxic and harmful substances, thereby maintaining the stable growth of microorganisms such as methanogens, improving the efficiency and stability of anaerobic digestion, and thus reducing harmful components in solid waste. The utility model can not only effectively prevent and control solid waste, but also save water and time, and greatly improve the efficiency of environmental protection.
