Abstract

PROBLEM TO BE SOLVED: To provide a method for preventing the leakage of the hazardous material included in refuse from a refuse depot into the ground. SOLUTION: The entire part of the front surface of a mound M of the refuse in the refuse depot, such as open stock yard, is covered with a waterproof cover 1 to prevent the infiltration of rainwater and to put the inside of the mound of the refuse into a dry state, by which the elution of the hazardous material included in the refuse into the water is prevented. In addition, the moisture and water are sucked into the refuse from the inside of the ground by the sucking up of the steam by the steam percolation pressure induced by a moisture difference between the mound M of the refuse and the ground surface G and the sucking up of the water by the capillarity occurring in the difference in the moisture content between the mound of the refuse and the ground surface, by which the stream of the water heading toward the mound M of the refuse from the inside of the ground is created and the generation of the stream of the hazardous material included in the refuse from the mound of the refuse into the ground is prevented. The leakage of the hazardous material into the ground is thus completely prevented.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a garbage storage.

[0002]

2. Description of the Related Art Garbage is increasing everywhere in the country every year, but there is no place to store garbage. The reason for this is that the management of the garbage can hardly be done, causing environmental problems in various places, and the consent of the local residents about the establishment of the garbage can not be obtained. The environmental problems include pollution of groundwater, generation of odor, generation of toxic gas and destruction of landscape.

As shown in FIG. 5 (thick arrows in the figure indicate the direction of water flow), harmful substances such as heavy metals contained in the garbage are contaminated by rainwater falling on the garbage pile. It melts and pools (water pool P shown in FIG. 5), which penetrates underground and mixes with groundwater.
Also, when the surface of the garbage pile gets wet with rainwater, the water strongly penetrates into the garbage pile by capillary action,
A phenomenon occurs in which the gas inside the pile of garbage that is trapped is compressed and the pressure rises. When harmful substances dissolve in water and exist above the ground, they are strongly pushed underground due to the pressure of the gas inside the pile of garbage. This harmful substance pollutes groundwater and soil. If there is a well in a nearby private house H, the well water W is contaminated.

Normally, as a countermeasure, a water leakage prevention treatment such as a waterproof sheeting, a concrete sheeting K, and a waterproof sheeting is applied on the concrete sheeting. However, even if it is intended to be completely treated, the waterproof function will be impaired due to seams, tears, cracks, etc., and it will be avoided that the material used will deteriorate with the passage of time and the loss of the waterproof function will increase. I can't. Due to the pressure of the gas generated inside the refuse mountain, leakage of harmful substances may occur even if the rupture or crack is extremely small.

Further, as shown in FIG. 6 (the thin arrows in the figure indicate the direction in which the odor or toxic gas flows), the odor or toxic gas is generated in the garbage pile in the presence of moisture. It is generated by the spoilage of the garbage (the spoiled layer F of the garbage shown in FIG. 6) or the chemical reaction of the contaminant being promoted under a high temperature state caused by heat of fermentation. The reaction of various chemical substances causes volatilization, ignition, and smoke of the petrochemical raw material product. In addition, a strong odor is generated depending on the type of garbage, and the number of inhabitants who can not live near the garbage storage area and abandon the house H and escape to other areas is increasing.
There are also phenomena in which real estate as property and land prices are falling because the garbage storage is nearby. When ignited, the petrochemicals contained in the garbage are chemically transformed into harmful gases and harmful chemicals. Once the harmful chemicals are formed in the garbage, there are few effective countermeasures at present.

[0006] In addition, if there is garbage, birds such as crows, small animals such as rats, and insects such as flies gather or generate from the garbage, which is extremely unsanitary. Large piles of garbage can ruin the landscape if the garbage is left bare, making the viewer uncomfortable. If such a state is left forever, the surrounding residents will feel at risk of life, and become anxious just by being aware of the existence of the garbage dump. At present, no one in the area has responded effectively to such problems, and the residents of the area have opposed the establishment of garbage depots.

[0007]

DISCLOSURE OF THE INVENTION The present invention has been made in view of the above circumstances, and eliminates the generation of harmful gas and odor from a garbage storage area, and the harmful substances contained in the garbage leak into the ground. The aim is to provide a method that can completely prevent the garbage, and to remove the anxiety of the local residents who have garbage dumps.
