Abstract
The invention relates to a method and device for accelerating the decomposition of biogenic organic matter in refuse disposal sites. According to the method, at least one suction line is inserted into a disposal site debris heap (11) via which the arising refuse site gases are removed by suction. According to the invention, the quantity of gas removed by suction in the area of the bottom of the refuse disposal site should be greater than the quantity of gas arising in this area due to decomposition whereby enabling oxygen from the outside air to penetrate into the debris heap and transforming the decomposition process into an, at least to a large extent, aerobic decomposition.
Claims11
A method of accelerating the decomposition of biogenic organics in garbage dumps in which the garbage is deposited upon a garbage dump ground (21) in a heap or pile (11) in which a suction line is included by which the dump gases produced the heap or pile are sucked out,
- characterized in,
- that the gas quantity sucked from the region of the dump ground is greater than the gas quantity arising in this region from decomposition so that oxygen in atmospheric air from the exterior penetrates into the pile or heap (11) and transforms the decomposition process into a decomposition which is at least mostly an aerobic decomposition.
An apparatus for measuring the gas position at different depths, characterized in that filter cartridges for gas sample-taking are embedded in a bore in preferably one meter great gravel layers in which preferably each one meter thick layer of filter gravel and clay are disposed in layers alternately with one another.
