METHOD OF THE BIOGAS COLLECTION AND WITHDRAWAL AT THE POLYGON OF THE SOLID DOMESTIC AND INDUSTRIAL WASTES Russian patent published in 2007 - IPC B09B1/00 

FIELD: environmental protection; decontamination of the solid domestic and industrial wastes.

SUBSTANCE: the invention is pertaining to the environmental protection, in particular, to the decontamination of the solid domestic and industrial wastes and may be used for collecting and withdrawing of the biogas formed in the depth of the domestic and industrial wastes (DIW) polygon. The technical result of the invention is expansion of the technological capabilities at degassing of the DIW and decreasing of the harmful effect on the environment due to reduction of the harmful biogas outbursts in the air and withdrawal of the biogas for utilization at the DIW polygon operation simultaneously with allocation of the scrap. For this purpose on the polygon of the solid domestic and industrial wastes perform the preparation of the foundation, mounting of the system of the vertical gaseous drain from the net of the located on the polygon area wells with the perforated walls and the external filtrating earth-bank formed with the help of the sliding sheathing, the layer-by-layer placing of the wastes with the intermediate insulating layers, raising the wells in height of each layer of scrap; withdrawal of the biogas from the wells of the vertical gaseous drain is realized using the tubular drains of the horizontal drainage in the foundation of the DIW polygon. At that the lower links of the tubes of the wells of the of the vertical gaseous drain connect with the drainage wells of the horizontal tubular drains, and the upper ends of the wells of the vertical gaseous drainage shut by the plugs, which are installed after each cycle of the raise on the upper end of the sliding sheathing.

EFFECT: the invention ensures expansion of the technological capabilities at degassing of the domestic and industrial wastes (DIW), decreasing of the harmful effect on the environment, reduction of the harmful biogas outbursts into the air and withdrawal of the biogas for utilization at the DIW polygon operation simultaneously with allocation of the scrap.
