不同类型废物原料硫酰氟熏蒸通风散毒时效研究

Study on Sulfuryl Fluoride Fumigation and Ventilation Time of Different Kinds Waste Materials

为科学评价不同类型废物原料硫酰氟熏蒸后散毒的时长,以废塑料、废纸和废金属三种主要固体废物原料为研究对象,研究集装箱硫酰氟熏蒸后通风散毒硫酰氟气体浓度的变化。结果表明,在温度一定的条件下,硫酰氟气体的衰减速率由快到慢的顺序依次为:废金属>废塑料>废纸,且随着温度的升高,同一种固体废物原料中硫酰氟的衰减速率越快。

To study the decay time of waste plastics,paper and metal after sulfuryl fluoride(SF)fumigation in the container.The result show that,in certain temperature,SF decay rates from fast to slow was metal>plastic>paper,and SF decay rates in the same solid waste materials are more faster with the increasing of temperature.
