Additionally, reducing the PCDD/F emission from the stack flue gas by adding antioxidation enzyme is also investigated. The conclusions of this study are summarized as follows: First, at steady operation, the mean PCDD/F concentrations in the stack flue gases of MSWI S and C are 0.0408 and 0.179 ng I-TEQ/Nm3, respectively. Secondly, in start-up of the MSWI-S, the mean PCDD/F concentrations in the stack flue gas is 13.8 ng I-TEQ/Nm3 and a total of 35.2 mg I-TEQ of PCDD/Fs was estimated in the start-up period. The PCDD/F emission in start-up equals 40.5% of one year emissions in steady operation. Thirdly, the PCDD/F removal efficiency by bag filters of MSWI-S and MSWI-C were 99.8% and -340%, respectively. The negative PCDD/F removal efficiency of MSWI-C may be owing to the memory effect. After replacing filters, the PCDD/F removal efficiency reached 70.9%. Finally, after spraying antioxidation enzyme, the PCDD/F concentration in the stack flue gases of MSWI-S is declined, and reaches the lowest point since MSWI-S started operation. In addition, the five PCDD/F concentrations of one stack flue gas sampling have less deviation than former data. In summary, the effect of spraying antioxidation enzyme on the PCDD/F concentration in the stack flue gases of MSWI-S is obvious. Wen-Jhy Lee 李文智 2004 學位論文 ; thesis 114 zh-TW |
