中文摘要 | 本試驗的目的在探討三段式豬糞尿處理過程中所產生的初步沉澱污泥、厭氣發酵 污泥及好氣發酵污泥施用於土壤後,其氨之揮發作用及碳之礦質化作用。污泥施用於土壤濃 度為5%,土壤水份張力1/30 MPa,試驗溫度30±2℃,試驗期間以馬達充份通氣。試驗結 果顯示,污泥施用於土壤後,經過十八天的通氣培育,好氣發酵污泥、初步沉澱污泥及厭氣 發酵污泥分別有10.7、11.9及15.6%的氮經由氨的揮發而消失。如將揮發的氨態氮與試驗前 污泥中的銨態氮比較,好氣發酵污泥的揮發性氨態氮佔銨態氮的90%左右。初步沉澱污泥 及厭氣發酵污泥的揮發性氨態氮則分別佔銨態氮的70及58%。 污泥碳在土壤中的礦化量,經過九週的通氣培育,好氣發酵污泥、厭氣發酵污泥及初步 沉澱污泥的CO -C在10g土壤中的累積產量分別為57.6、193.0及113.0mg。分別佔原污 泥中全碳的32、80及48%。 由氨的揮發及CO 的產生量判斷,豬糞尿處理所產生的三種污泥施用於土壤後,以好 氣發酵污泥較穩定,而厭氣發酵污泥最不安定,最易分解。 |
英文摘要 | The objectives of this study were to determine the ammonia volatilization and carbon mineralization from primary sedimentary sludge, anaerobic sludge and aerobic active sludge which were applied in soil. The sludges were mixed with soil at 5% and incubated at 30±2℃ under 1/30 Mpa water potential. The incubators were aerated by pump during the experimental period. The results showed that the loss of total nitrogen through NH volatilization from primary sedimentary sludge, anaerobic sludge and aerobic active sludge 18 days after aerating incubation with soil were 11.9, 15.6 and 10.7%, respectively. The amounts of NH3 volatilization to the initial NH -N contents in hog waste sludge were 90, 70 and 58% for aerobic fermentation sludge, primary sedimentary sludge and anaerobic fermentation sludge, respectively. The cumulative amounts of CO -C evolved from anaerobic fermentation sludge, anaerobic fermentation sludge and primary sedimentary sludge were 57.6, 193.0 and 113.0mg, 9 weeks after aerating incubation with 10g soil, respectively. The co –C evolved to total carbon in the hog waste sludge were 32, 80 and 48% for aerobic fermentation sludge, anaerobic fermentation sludge and primary sedimentary sludge, respectively. The results showed that the aerobic fermentation sludge was the most stable, followed by primary sedimentary sludge and anaerobic fermentation sludge. |
