中文摘要 | 畜牧業養豬放流水之水質於民國87年以後必須達到懸浮固體15Omg/l、化學需氧量 250mg/l 與生化需氧量 80mg/l 以下之要求。為使達到該新標準,本試驗探討填加生物濾材 之生物反應槽,處理符合民國 82 年環境保護標準之養豬放流水及兼氣發酵後之廢水,經間 歇缺氧及曝氣處理後對其懸浮固體、化學需氧量及生化需氧量等之改善效果。試驗處理組與 無填加生物濾材但有經曝氣處理之對照組比較,結果顯示: (1) 填加濾材於兼氣後廢水處理 單元對化學需氧量和生化需氧量的降低具有分解和減量之效果 (p<0.01); (2) 在水力停留 時間 24 小時之條件下,將已達民國 82 年環保標準之放流水以填加濾材之反應槽處理,對 懸浮固體具有再分解和減量之作用 (p<0.01); (3) 以水力停留時間 24 小時與採用填加濾 材之生物反應槽處理,其放流水水質可達 87 年之環保標準。 |
英文摘要 | Environmental Protective Standards (EPS) were revised by the Environmental Protection Administration (EPA), Executive Yuan. The suspended solids (SS), chemical oxygen demand (COD), and biochemical oxygen demand (BOD �� ) of pig's effluent standards were upgraded from 200 mg/l, 400mg/l, and 100 mg/l during 1993 to 150 mg/l, 250 mg/l, and 80 mg/l after 1998, respectively. For conforming with stricter EPS after 1998, advanced techniques on treating pig wastewater must be further investigated to imporve the quality of effluent. This study used bio-media submerged in effluent which met requirements of 1993 EPS and in wastewater after facultative fermentation (FF) and then further treated by aerated contact bioreactors. The effluent and wastewater without using submerged bio-media served as control treatments. The results of this experiment are summarized as follows: (1) using aerated contact bioreactors in waste water of FF for 24 hours hydraulic retention time (HRT), the chemical oxygen demand (COD) and BOD �� were highly significantly different (p<0.01) than the control; (2) the effluent met requirements of 1993 EPS treated by aerated contact bioreactors for 24 hr HRT; the SS was highly significantly different (p<0.01) than control, and (3) use of HRT for 24 hr and aerated contract bioreactors reducied the SS, COD, and BOD �� of effluent. It was pure enough to meet the 1998 EPA. |
