METHOD OF SOLID DOMESTIC WASTE STERILISATION AT SOLID DOMESTIC WASTE DUMP Russian patent published in 2008 - IPC B09B1/00 

FIELD: technological processes.

SUBSTANCE: method includes preparation of dump base, arrangement of fencing structures, erection of antifiltering screen, drain system for collection and treatment of filtrate, and also of gas collection system, layerwise installation of waste with soil isolating layers, provision of insulating coating of arranged dump surface. Territory of dump is divided into working sections in amount of at least three. Every section of dump is formed as independent from the others. Filling of every subsequent section with waste is started on completion of the previous section filling. Extraction and recycling of waste from the area of the first filled section and its preparation for repeated filling is performed in the period of the last section filling with waste, then on the prepared territory of the first section waste is repeatedly placed, with simultaneous extraction and recycling of the second section waste with its preparation for repeated filling, after that cycle is repeated according to the sequence of the sections' initial filling. Ratio of the average duration of one section filling and number of sections is calculated with the help of mathematical dependence.

EFFECT: increase of efficiency of land lots usage as solid domestic waste refuse dumps and increase of their service life.
