摘要：在进水ＣＯＤ为５００—６００ｍｇ／Ｌ、压力ｐ＝０．２ＭＰａ、回／流比Ｒ＝６条件下，加压上流式好氧污泥床平均ＣＯＤ去除率为７１％，出水基本达到国家排放标准（１００ｍｇ／Ｌ）；进水ＣＯＤ为１０００ｍｇ／Ｌ以上，在ｐ＝０．３ＭＰａ、Ｒ＝６条件下，ＣＯＤ去除率仍可达到７０％左右．实验发现，压力ｐ＝０．３ＭＰａ时最佳ＢＯＤｓ容积负荷为２０ｋｇ·（ｍ３·ｄ）－１左右，进水ＣＯＤ大于１０００ｍｇ／Ｌ，压力ｐ＝０．４ＭＰａ时最佳回流比为９，最短停留时间可达到１５．４ｍｉｎ．停留时间和容积负荷分别为传统活性污泥法的１／１０—１／２０和１０倍以上，可大大节约占地面积．
When the influent COD of pharmaceutical wastewater was in the range of 500—600mg/L,effluent through Pressured Upflow Aerobic Sludge Bed (PUASB) can attain the national emission standard under the operation condition of surface pressure ( p ) 0 2MPa,return ratio( R )6.Even if influent COD was more than 1000mg/L,the COD removal rate was near to 70% ander p =0 3MPa.Results also showed that the optimal BOD volume load is about 20kg·(m 3·d) -1 with the pressure 0 3MPa,the optimal return ratio is 9 and the lowest retention time reaches 15 4 min with the pressure 0 4MPa and influent COD more than 1000mg/L.The lowest time is only 1/10—1/20 times and BOD volume load is about 10 times as much as traditional activated sludge process,and the land use is reduced greatly.
