中文摘要 | 本試驗旨為評估不同生物濾材對豬舍產生之氨氣及異味的去除率。試驗將密閉式豬舍高床下之空氣,注入裝填蛇木屑 (fern chips, F)、蛇木屑混合堆肥 (fern chips mixed with compost, FC)、椰殼纖維 (coir, C)及椰殼纖維混合堆肥 (coir mixed with compost, CC) 4種濾材之管柱,設定空床停留時間 1 min,於管柱進出口量測氨氣及異味濃度。結果顯示管柱進口之平均氨氣與異味濃度為 7.3 ppmv與 175,經過 F、FC、C及 CC組濾材處理後之出口氨氣濃度與異味濃度平均分別為 0.2、0.5、0.3及 1.8 ppmv與 22.2、16.9、18.6及 24.1,去除效果顯著。平均氨氣去除率以 CC組之 75%,顯著低於其他各組之 92%以上去除率 (P < 0.01)。異味去除率 F、FC、C及 CC組分別為 87.3%、90.3%、89.3%及 86.2%,各處理組間無顯著差異。管柱試驗結果顯示,使用蛇木屑、蛇木屑混合堆肥及椰殼纖維做為濾材,可做為密閉式高床豬舍床下空氣中氨氣與異味的去除材料,惟實場規模生物濾床試驗尚待進行。 |
英文摘要 | The purpose of this study was to evaluate the effect of different biofilter media on reducing ammonia and odor emissions from a pig house, for meeting the environmental regulations promoting air quality in the pig farm. Air beneath the slotted floor in the closed pig house was conducted into four pilot-scale biofilter columns filled with fern chips (F), fern chip mix with compost (FC), coir (C) and coir mix with compost (CC), respectively. The empty bed retention time (EBRT) was set at 60 second, and the ammonia and odor concentrations in the inlet and outlet gases of each column were measured. Results showed that the averages of the inlet concentrations of ammonia and odor were 7.3 ppmv and 175, respectively. Average concentrations of ammonia and odor after treating by F, FC, C and CC biofilters were 0.2, 0.5, 0.3, 1.8 ppmv and 22.2, 16.9, 18.6, 24.1, respectively. Ammonia and odor removal efficiencies of these biofilters were significant. CC biofilter had a significantly lower ammonia removal rate (75%) than others ( > 92%, P < 0.01). The odor removal rates by F, FC, C and CC biofilters were 87.3, 90.3, 89.3 and 86.2%, respectively and there was no significant difference among biofilters. The results show that F, FC and CC biofilters can reduce ammonia and odor emissions beneath the slotted floor in the pig house. However, a full-scale biofilter study still needed to evaluate the feasibility of this technology. |
