TH44672A - Mechanical-biological treatment of household waste - Google Patents

Abstract

DC60 (27/11/52) This invention refers to a method for the mechanical-biological treatment of local waste and the use of appropriately decomposed straw piles to improve the efficiency and sanitation of household waste treatment. The decomposed straw piles are covered with a structural layer of material size 25 to 80 millimeters and then covered with another covering layer, with the height of the decomposed straw pile not exceeding 2.80 meters. This invention refers to a method for the mechanical-biological treatment of local waste and the use of appropriately decomposed straw piles to improve the efficiency and sanitation of household waste treatment. The decomposed straw piles are covered with a structural layer of material size 25 to 80 millimeters and then covered with another covering layer, with the height of the decomposed straw pile not exceeding 2.80 meters.

Claims (9)

1. Mechanical-biological treatment of household waste where household waste has been broken down into small pieces and homogeneously mixed and then subjected to biological treatment in a well-aerated (1) hay bale by ventilation by a stack height (H) of no more than 2.80 m, where a structural layer (13) of at least 25 to 80 mm particles is placed on top of the household waste (9) and a covering layer (12) is placed on top of the structural layer. 2. The method specified in claim 1 is special in that the height of the pile of decayed straw (1) is at least 2 meters. 3. The method described in Claim 1 or 2 is characterized by the fact that the structural and covering layers are approximately 15 centimeters thick each. 4. A compost pile for the bioremediation of fragmented and homogeneous household waste (9), which is stored in an air-permeable material (5) through which at least one ventilation pipe (4) is placed, through which air (A) is drawn from the atmosphere by means of a chimney ventilation system to a chimney (3) placed in the compost pile (1) to ventilate the household waste (9), which must at least consist of a structural layer (13) placed on top of the household waste (9); such structural layer consists of material of a size of 25 to 80 mm and must at least consist of a covering layer (12) placed on top of the structural layer, where the height of the compost pile (1) is not more than 2.80 m and the width (b) of the compost pile, which is designed to fit the ventilation unit (4), is not more than 3 m. 5. The decaying straw pile as specified in claim 4 is of a special nature in which the air-permeable particles consist of at least one mat made of wood (5a, 5b). 6. The decaying straw pile as described in claim 5 is of the nature that mats (5a, 5b) are placed in an area through which ventilation unit (4) passes, in which the first two mats (5a) are placed close together with a distance (d) less than the width of the mat (e), and a third mat (5b) is placed on top of the two mats (5a), creating a gap (10) through which ventilation unit (4) passes. 7. The decaying straw pile as specified in any of the claims of Claims 4 through 6 has special characteristics in which the ventilation unit (4) is a perforated pipe as appropriate using PVC pipe. 8. The decaying straw pile as specified in claim 6 has a special characteristic in that 3 to 6 mats are suitable for use with 4 mats placed close together, perpendicular to the placement of the ventilation unit. 9. The decaying straw piles as specified in any of the claims in Claims 4 through 8 are of a special nature in that their height (H) is at least 2 meters.
