摘要: Polychlorinated dibenzo-p-dioxin and polychlorinated dibenzofuran (PCDD/F) emission characteristics vapour/particulate phase partitions under three continued operation conditions, i.e. shut-down, start-up after start-up, were investigated by sampling stack gas. The results indicated that the PCDD/F levels 0.40–18.03 ng I-TEQ Nm −3 , much higher than annual monitoring level (0.016 ng ). Additionally, in other two conditions. Furthermore, congener profiles differed markedly between shut-down chlorination degree of increased decreased evidently start-up. Moreover, distributions varied significantly transient vapour proportion as process continued, then proceeded, finally more 98% congeners distributed correlations log( C v / s ) versus log p L 0 each gas disorganized trend to a linear distribution Besides, biphenyl emissions show behaviour similar PCDD/F, lower chlorinated have stronger relationship with 2,3,7,8-PCDD/Fs, such M1CB D2CB.
