中文摘要 | 本研究旨在評估狼尾草 (Pennisetum purpureum)臺畜草 3號及青貯玉米 (Corn silage)取代部分飼料餵飼肉豬之排泄物對廢水處理之影響。試驗採用 40頭平均體重 80公斤之肉豬,逢機分配至 5個處理組,即一般飼糧組 (BD)、2.5 kg一般飼糧加狼尾草任食組 (2.5 BDN)、3 kg一般飼糧加狼尾草任食組 (3.0 BDN)、2.5 kg一般飼糧加青貯玉米任食組 (2.5 BDC)及 3 kg一般飼糧加青貯玉米任食組 (3.0 BDC)。收集前述五個處理組的豬糞尿分別添加自來水後經固液分離、厭氣及好氣程序之處理效果。試驗結果顯示, 5組豬糞尿廢水經固液分離後之 COD、BOD及 SS無統計差異,經厭氣處理後 COD、BOD及 SS濃度分別介於 492-636 mg/L、113-178 mg/L及 114-158 mg/L,去除率分別達 87%、88%及 95%以上,經好氣處理後 COD及 BOD去除率達 51%以上。 BD、2.5 BDN、3.0 BDN、2.5 BDC及 3.0 BDC等組之沼氣產量分別為 140、139、136、154及 146 L/kg COD/d,無顯著差異。 |
英文摘要 | The objectives of this study were to evaluate the effects of feeding two sources of domestic forage, including napiergrass and corn silage, on wastewater treatment of finishing pigs. Forty LYD finishing pigs (half barrows and half gilts) at averaging 80 kg BW were randomly assigned to individual pens. The pigs were randomly allotted into five treatments with 8 replications. The 5 treatmental groups were as follow : BD (basal diet ad libitum) (control group), 2.5 kg BD with napiergrass ad libitum (2.5 BDN), 3 kg BD with napiergrass ad libitum (3.0 BDN), 2.5 kg BD with corn silage ad libitum (2. 5 BDC) and 3 kg BD with corn silage ad libitum (3.0 BDC). All the forages and water allowed to acces ad libitum. The slurry samples of each treatment were collected and conducted to the simulating wastewater treatment facilities. The results showed that the COD, BOD and SS of influent were not significantly different among five groups. In anaerobic treatment stage, the COD, BOD and SS of effluent were 492-636, 113-178 and 114-158 mg/L and the removal rate of COD, BOD and SS were above 87%, 88% and 95%, respectively. In aerobic treatment stage, the removal rate of COD and BOD were above 51%. The biogas yield of BD, 2.5 BDN, 3.0 BDN, 2.5 BDC and 3.0 BDC were 140, 139, 136, 154 and 146 L/kg COD/d, respectively. |
