Analysis of Operating Costs of Centralized Medical Waste Disposal Technology

摘要

Medical wastes are typical hazardous wastes. This paper chooses the pyrolysis decomposition technique for disposal of typical, medical wastes and addresses the relationship between facility operation costs, construction scale, technical route, operation time and the actual amount of waste collection through questionnaires. The final conclusions include the operation costs of different sizes of medical waste disposal facilities; the inverse correlation between the disposal cost per unit and construction capacity, where 15-ton projects involve the lowest disposal cost; the technical route is not a major factor to the disposal cost per unit; the actual amount of disposal (collection) and operation time have a direct effect on the per unit disposal cost. The shorter the operation time was, the greater the deviation of the amount of waste collection from the designed capacity was, and the higher the operation cost. On the contrary, the operation cost is more reasonable, and stays stable when the disposal facility can steadily operate at a certain collection rate (above 70%).
