Method for building green pyramid landscape with unrecyclable rubbish

Abstract

The invention discloses a method for building a green pyramid landscape with unrecyclable rubbish. The method comprises the following steps: manufacturing unrecyclable rubbish and solid waste of factories and mines into fluid state rubbish slurry through the technologies of preprocessing, pulping, smashing and mixing; after treating a pyramid site, building a central tower, a water drainage facility, a gas exhausting facility, a passage and other ancillary facilities; based on the central tower, utilizing a greening bag cofferdam to discharge the rubbish slurry, and heightening layer by layer to form a pyramid-shaped rubbish heap body; arranging a layered draining and seepage system in the rubbish heap body, arranging a negative pressure air water header pipe in the central tower to guide waste water to an off-site cesspit for cyclic utilization and guide waste gas into an air exhausting device at the top of the central tower for unified treatment; immediately greening the slope surface of the pyramid to fully cover the rubbish heap body not to impair the landscape of the appearance of a city, and basically eliminating pollution of waste water and waste gas to the environment; under effective management and control, after degradation, fermentation and ageing function of 20-30 years, forming high-quality compost or harmless soil by the pyramid heap body, and converting the high-quality compost or harmless soil into resources for urban ecological construction or feeding back the agriculture.

Description

Technical field [0001] The invention belongs to the technical field of urban sanitation Background technique [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 garbage, etc., and it is also mixed with packaging, waste clothing, polluted paper, and other sundries For non-recyclable garbage, the current treatment methods in most cities are basically extensive burying and concentrated stacking, which has caused increasingly serious environmental problems; Japan’s garbage classification is more refined, and kitchen waste is specifically removed for use Composting is turned into agricultural resources; China’s burying and stacking of non-recyclable garbage is similar to composting and natural fermentation. The actual effect is that pollution is centralized, which only reduces the number of pollution sources and does not transform th...

[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
