进境原木熏蒸的溴甲烷重复利用技术应用研究

Application research on methyl bromide re-using technology in imported logs fumigaton

太仓港进口木材检疫除害处理区拥有先进的熏蒸处理设施。本文对进境原木熏蒸的溴甲烷重复利用技术进行了应用研究，结果表明：（1）区内倒仓30min、区间倒仓40min为实现溴甲烷重复利用的最适倒仓时间；（2）本处理区条件下溴甲烷重复利用率在30％～40％之间；（3）2种倒仓方式对溴甲烷的重复利用率影响不显著，但环境温度、仓容与材积的比值有较明显的影响。

Taicang port imported timbers quarantine treatment ties. In this paper, the methyl bromide re - using technology zone possess advanced fumigation treatment faciliin imported logs fumigation applied research. Resuits showed that ： （ 1 ） The optimum transfer time of methyl bromide re- use is 30min within the same area, and 40min between two areas. （2） The ratio of methyl bromide re - use is about 30% to 40% in this zone. （3） The influenee to the ratio of methyl bromide re - use between the two transfer patterns is not remarkable. But the envi- ronment temperature and the proportion of the tank capacity to logs volume have a more significant impact.
