| 中文摘要 | 國內養雞場常見導致粉塵逸散問題,且易引發附近居民陳請。本研究是以各種粒徑粉塵對於進行之逸散防制(含防塵網鋪設、噴霧灑水作業、防塵屏設置)研究,以評估各有逸散防制設施之效能,並引進國外已具成熟技術之高效率粉塵逸散防制設施,且於養雞場現場進行效能評估作業,期能有效的達到除塵目的。本研究乃規劃設計高效率且低成本之粉塵逸散防制設施,如防塵布架設與高效率噴霧設施設置,且洽尋五家代表性養雞場進行逸散粉塵污染改善工作,以期實際降低粉塵排放情形。 研究結果得知於養雞場下風處,粉塵濃度常高達600 µg/m³以上,即使減去上風處粉塵濃度,其上下風濃度差極易超過國內畜牧場周界標準500 µg/m³。另於養雞場下風處量測粉塵粒徑分布,得知其中粒徑僅為5 µg,遠小於目前一般設置之防塵網網目(約為0.1~1.0mm),致使既存設施無法發揮除塵功能,並導致嚴重粉塵排放。所量測養雞場之粉塵中TSP、PM[fede]與PM□質量濃度各約為296~674、135~233、53~178 µg/m³。各養雞場粉塵逸散濃度依序為A養雞場>B養雞場>D養雞場>C養雞場>E養雞場 。本研究針對防塵網效率評估結果得知TSP、PM[fede]與PM□控制效率分別為38.4、29.3與7.0%;若同時採用防塵網與噴霧效率,則TSP、PM[fede]與PM□控制效率分別為47.5、40.8與18.5%。 |
| 英文摘要 | The dust is easily emitted from chicken farm and causes a lot of complain from neighborhood. It is important to build control strategies to prevent pollution from chicken farm. The assessed control strategies include dust prevention net laying, water spraying and wall establishment. The control efficiency assessment was executed in this study. Furthermore, several kinds of particulate measurement equipment were introduced to study the effectiveness of dust prevention. The purposes of this study were to establish the best available and effective control techniques. Several kinds of pollutants, such as TSP, PM[fede] and PM□ and particle size distribution were tested in five chicken farms. After analyzing the concentrations reduced with using control equipment, the effectiveness of control strategies could be available. The results showed that the TSP concentration could be up to 600 μg/m at the downwind area and be easily beyond the emission standard. The mass median diameter was 5μm and more smaller the conventional mesh size of dust prevention net. The TSP, PM[fede] and PM□ concentrations was roughly 296~674, 135~233 and 53~178 μg/m, respectively. It can cause environmental problem and human health harm. After assessing the performance of control equipment, the TSP, PM PM[fede] and PM□ control efficiency of using dust prevention net was roughly 38.4, 29.3 and 7.0%, respectively. Furthermore, the efficiency of TSP, PM[fede] and PM□ could be increased to 47.5, 40.8 and 18.5%, individually, with dust prevention net and water spray simultaneously. The emitted dust concentration can obey the standard of the national air quality after adopting control strategies. |
