中文摘要 | 本研究採實驗室規模之厭氧/無氧/好氧(單一污泥)系統,當豬糞尿廢水進流之 COD/TKN比值為2.0∼2.9且在COD、TKN及TP負荷分別為0.140∼0.192 kg-COD/kg-MLVSS- d (0.35∼0.59 kg-COD/m□-d)、0.066∼0.083 kg-N/kg-MLVSS-d (0.12∼0.29 kg-N/m□-d) 及0.0082∼0.0093 kg-P/kg-MLVSS-d (0.017∼0.032 kg-P/m□-d)以及污泥迴流比0.5、混 合液迴流比1∼2時,單一污泥型系統之COD、TN及TP去除率分別為81.1∼89.5%、59.6∼ 68.0%及 22.3∼29.1%。當高含氮、含磷合成廢水進流之COD/TKN比值為3.1∼6.9且在COD、 TKN及TP負荷分別為0.318∼0.95 kg-COD/kg-MLVSS-d (0.43∼2.5 kg-COD/m□-d)、0.093 ∼0.290 kg-N/kg-MLVSS-d (0.13∼0.55 kg-N/m□-d)及 0.0111∼0.0343 kg-P/kg-MLVSS-d(0.015∼0.065 kg-P/m□-d)以及污泥迴流比0.5∼1、混合液迴流比1∼3 時,該系統之COD、TN及TP去除率分別為93.3∼97.4%、39.9∼69.2%及18.6∼25.7%;但須 指出者,TKN轉化率、TN去除率及COD去除率皆有隨脫硝負荷之增加而緩慢降低之趨勢,且 當COD/TKN之比值高達6.9時會導致無氧槽之脫硝效率顯著地降低。 經由懸浮生長式批次反應槽之測定, 厭氧槽和無氧槽之脫硝動力及好氧槽之硝化動力皆可視 為零階反應,其脫硝及硝化反應速率常數分別為1.4d□、0.16d□及0.31d□。此外,由連續 流懸浮生長式污泥系統之理論動力式求得脫硝異營菌及硝化自營菌之污泥增殖係數觀測值分 別為0.63(NO□-N basis)及0.08(TKN basis)。 本研究推導之動力模式經實驗數據(厭氧、無氧、好氧三個反應槽實測污泥濃度之平均值及 TKN和NO□-N濃度)驗證後確實適合應用於預測單一污泥型系統之除氮能力,又經由模式之 模擬結果發現混合液迴流比及好氧槽容積皆有一最佳值,超過此值並無法增加TKN轉化率及 TN去除率。 及TN去除率。 |
英文摘要 | Two sets of identical laboratory-scale single-sludge reactor system consisting of anaerobic, anoxic, and aerobic compartments were operated to ascertain its capability in treating high-strength nitrogen-and phosphorus-containing swine wastewater. When the influent swine wastewater with COD/TKN ratios of 2.0 to 2.9, COD loadings of 0.140 to 0.192 kg-COD/kg-MLVSS-d (0.35 to 0.59 kg-COD/m□-d), TKN loadings of 0.066 to 0.083 kg-N/kg-MLVSS-d(0.12 to 0.29 kg-N/m□-d), TP loadings of 0.0082 to 0.0093 kg-P/kg-MLVSS-d (0.017 to 0.032 kg-P/m□-d), sludge recycle ratio (R□) of 0.5, and mixed liquor recycle ratios (R□) of 1 to 2 were maintained, the removal efficiencies of COD, TN, and TP were 81.1∼89.5%,59.6∼68.0%, and 22.3∼ 29.1%, respectively. When the influent synthetic wastewater with COD/TKN ratios of 3.1 to 6.9, COD loadings of 0.318 to 0.95 kg-COD/kg-MLVSS-d (0.43 to 2.5 kg-COD/m □-d), TKN loadings of 0.093 to 0.290 kg-N/kg-MLVSS-d (0.13 to 0.55 kg-N/m□-d), and TP loadings of 0.0111 to 0.0343 kg-P/kg-MLVSS-d(0.015 to 0.065 kg-P/m□-d), R□ of 0.5 to 1, and R□ of 1 to 3 were maintained ,the removal efficiencies of COD, TN, and TP were 93.3∼97.4%, 39.9∼69.2%, and 18.6∼25.7%, respectively. Also, an increase of denitrifying loading resulted in slight decreases of TKN conversion and TN and COD removal, and a high COD/TKN ratio of 6.9 resulted in a drastic decline of TKN removal. Denitrification in the anaerobic and anoxic compartments and nitrification in the aerobic compartment, which were conducted by using three respective suspended-growth batch reactors, followed zero-order kinetics with rate constants of 1.4d□, 0.16d □, and 0.31d□, respectively. According to the kinetics of continuous-flow suspended-growth reactor system, the observed yield coefficients of denitrifiers and nitrifiers obtained from multiple regression were 0.63 (No□-N basis) and 0.08 (TKN basis), respectively. The calculated results (of the average MLVSS concentration of anaerobic, anoxic and aerobic compartments and the TKN and No□-N concentrations in the effluent of anaerobic, anoxic, and aerobic compartments) using the kinetic model were in good agreement with the experimental data. Thus, the proposed kinetic model could be used to predict nitrogen removal of the single-sludge reactor system. The simulated results also indicated that an optimum R□ and aerobic reactor volume for the better performance of the single-sludge reactor system existed, and the TKN conversion and TN removal remained unchanged when the R□ and aerobic reactor volume exceeded their optimum values. ptimum values. |
