摘要/Abstract

摘要： 为探索一种新型口罩在需氧和厌氧两种堆肥条件下的生物降解性能差异，采用国际上广泛认可的标准方法分别开展研究，获得了该新型口罩的生物降解率数据。统计分析结果显示，在ISO 14855?1和ISO 15985试验条件下，新型口罩在第90天时的生物降解率分别为66.4 %和21.2 %，该新型口罩在需氧条件中的生物降解性能远优于厌氧条件。研究表明，该新型口罩废弃后，宜采用需氧工业堆肥装置进行处理。

Abstract: To explore the difference in the biodegradation performance of a new type of masks under two composting conditions： aerobic and anaerobic， the biodegradation rates of the masks were obtained through the measurement according to the internationally recognized standard methods. The statistical results indicated that this type of masks exhibited biodegradation rates of 66.4 % and 21.2 %， respectively， on the 90th day under the test conditions of ISO 14855?1 and ISO 15985. This indicated that the masks had much better biodegradation performance in aerobic conditions than that in anaerobic conditions. This new type of masks may be more suitable for disposal with aerobic industrial composting devices after discarded.

Key words: new type mask, biodegradation, compost
