Problems solved by technology

But the land is still occupying idle, water resources, air and other types of pollution
Because there are some harmful microorganisms such as coliform bacteria and roundworm eggs in organic waste materials that still pollute water resources, and because stale domestic waste has lost water (water content is 10-15%) and the particle size of waste materials has become smaller, so under the action of wind , the garbage and dust are flying, causing adverse effects on the lives of the surrounding people, bringing pollution to the urban air, and forming a long-term source of water resources and air pollution.
It is understood that there is no stale domestic waste in our country that has been treated scientifically and rationally, so that the source of pollution can be cured and the land can be reused.

Embodiment 1

[0023] 1. Set a certain pile of stale domestic garbage, with an area of ​​50 mu = 33350m 2(Small Garbage Dump) is a long and narrow site with a length of 247 meters and a width of 130 meters. The highest point of domestic garbage piled up in the site is 9 meters, the lowest point is 0 meters, and the average height is 4.5 meters. The bottom width of the garbage pile is 80 meters and the length is 150 meters. The total volume of garbage is calculated as: 150×80×4.5=54000m 3 , the actual total quantity to be backfilled is: 54000×0.33=17820m 3 , the average backfill height (volume thickness): 17820÷33350=0.53m=53cm, set the amount of organic matter and inorganic matter to account for 50% respectively: 17820÷50%=8910m 3 . 0.33 is the reduction coefficient (due to the direct recovery of some items after sorting, and the reduction of inorganic and organic substances through drying, crushing, etc.).

[0024] 2. Use automatic domestic waste sorting machines to directly recycle plas...

[0037] Nutrient Soil Conditioner

[0038] ① The sorted organic matter is dried and sterilized (at a temperature of 200°C to 250°C) for 30 minutes by a rotary high-temperature (atmospheric pressure) dryer (rotary float), crushed by a hammer mill, and added with 5% slaked lime powder [ Ca(OH) 2 ], then add 5% of the 60-mesh high territory, and mix evenly with a mixer to become a powdery alkaline nutrient soil improver; the coliform value is 10 through biological experiments -2 100% mortality rate of roundworm eggs, tested water content of 8.6%, organic matter content (calculated as C) of 15.6%, experimental particle size of 85% through the 60-mesh sieve. Apply the alkaline nutrient soil conditioner to acidic or slightly acidic soil.

[0039] ② The sorted organic matter is dried by rotary floatation in a rotary high-temperature (atmospheric pressure) dryer, sterilized (at a temperature of 200°C to 250°C) for 30 minutes, pulverized by a hammer mill, and added with 8% gypsum powd...

Abstract

The invention discloses a comprehensive treating and in-situ backfilling method for a fermented life garbage stack, including the following steps: automatic sorting the fermented life garbage stack through an automatic sorter; directly reclaiming metal, plastics, paper, rubber, cloth, and electronic products, in-situ backfilling organics after a harmless process or producing nutritional type soil conditioners, mixing inorganics after the harmless process with the processed organics, in-situ backfilling the mixture based on the in-situ backfilling technology; reusing the soil after natural weathering, bioremediation and sediment for 3 years. The inventive method solves the difficult problems that the remained large fermented life garbage stack in cities and towns causes pollution to the surrounding ground, water resource, and air as well as occupies the ground for many years, enables the radical treatment of the pollution and the ground reuse.

Description

technical field [0001] The invention relates to a method for comprehensive treatment of accumulated stale domestic waste and backfilling in situ. Specifically, the stale domestic waste accumulated for many years can be classified and mechanically sorted, and seven types of materials can be sorted, and the sorted materials are classified separately. Recycling and the rest of the inorganic and organic matter are processed through innocuous treatment and on-site backfilling. In this way, the problems of environmental pollution and land occupation by stale domestic garbage accumulated for many years are solved, the environment is protected, and the land is restored to use. Background technique [0002] At present, my country's municipal solid waste treatment methods are generally divided into three types, one is sanitary landfill, the other is incineration, and the third is composting. So-called household garbage causes land, water resources, and air pollution, mainly caused by...
