How to build a green pyramid landscape with non-recyclable waste

Abstract

Using non-recyclable garbage and solid waste from factories and mines, through pretreatment, beating, crushing, mixing and other processes, make it into a liquid garbage slurry; after the pyramid site is treated, build the central tower and auxiliary facilities such as drainage, exhaust, and passages ; Relying on the central tower, use the planting bag cofferdam to discharge the thick slurry of garbage, and increase the height layer by layer to form a pyramid-shaped garbage dump; the garbage dump is equipped with a layered drainage system, and the central tower is equipped with a negative pressure air-water main pipe The waste water is led to the off-site sewage pool for recycling, and the waste gas is led to the exhaust device on the top of the center tower for unified treatment; the instant greening on the slope of the pyramid forms a full coverage of the garbage dump, and there is no landscape hindrance to the city appearance, and the waste water and waste gas have no impact on the environment. Pollution can also be basically eliminated; under effective control, the pyramid pile can form high-quality compost or harmless soil after 20 to 30 years of degradation, fermentation and aging, which can be transformed into resources for urban ecological construction or feedback to agriculture.

Description

[0002] Most cities in China are classified according to recyclable garbage, non-recyclable garbage and hazardous garbage; non-recyclable garbage is mainly kitchen waste, slag, construction and decoration waste, etc., mixed with packaging products, discarded clothes, polluted paper, and other sundries etc.; for non-recyclable garbage, the current treatment methods in most cities are basically extensive burial and centralized stacking, which has caused increasingly serious environmental problems; Japan’s garbage classification is more detailed, and kitchen waste is specially sorted out for recycling. Composting is turned into agricultural resources; China's landfill and stacking treatment methods for non-recyclable garbage are similar to composting and natural fermentation, the actual effect is the concentration of pollution, which only reduces the number of pollution sources, and does not transform the overall essence of pollution sources; analysis reasons: mainly garbage The plastic packaging and chemical fiber clothing in the environment are extremely difficult to decompose. These things are water-proof and gas-proof, forming a closed and harsh micro-environment ecology, which hinders the decomposition of bacteria and microorganisms and prevents the growth of plant roots. For example, this harsh micro-environment accumulates into a large amount of environmental pollution; such extensive waste disposal methods have caused many cities to form a disharmonious environment with both internal and external ice and fire. Surrounded by rubbish around the city, the stench is overwhelming; many cities adopt short-sighted behaviors of transferring rubbish to the countryside, which further aggravates the destruction of the ecological environment on a large scale; Turn waste into resources and completely eliminate the environmental hazards of urban waste
