WASTE VOLUME REDUCTION PROCESSING METHOD FOR WASTE DISPOSAL SITE

摘要

PROBLEM TO BE SOLVED: To provide a volume reduction processing device capable of effectively burying light weight wastes floating on water in a waste disposal site such as a landfill where a ground water level is high and ground water enters a non-discharge drilling hole.SOLUTION: The volume reduction processing device of the waste disposal site for drilling a non-discharge drilling hole 1 to throw a waste into the drilling hole 1 carries out the backfilling step of throwing a waste 21 of a heavy specific gravity to a predetermined depth in the non-discharge drilling hole to discard it, eliminating in-hole water 7 above the thrown and discarded waste to lower a water level, thereby throwing and discarding a light-weight waste 22, covering a hole 11 with a net 9 for preventing splashing of the light-weight waste, and throwing and discarding the light-weight wastes 21 and 23 again.SELECTED DRAWING: Figure 1
