【摘要】 通过现场生产性试验，对比上流式厌氧污泥床（ＵＡＳＢ）和复合式厌氧反应器处理高浓度中药废水的处理效果和运行稳定性，并后续好氧淹没式生物滤池，以探索一套完整高效的中药废水处理工艺，为生产应用提供依据。结果表明，当进水ＣＯＤＣｒ浓度为３８００ｍｇ／Ｌ～１５３２０ｍｇ／Ｌ时，复合式反应器平均出水６４９ｍｇ／Ｌ，ＵＡＳＢ平均出水１３１３３ｍｇ／Ｌ。当容积负荷为４５６ｋｇＣＯＤＣｒ／（ｍ３·ｄ）～１８３８ｋｇＣＯＤＣｒ／（ｍ３·ｄ）时ＣＯＤＣｒ平均去除率为９０８％，后续淹没好氧生物滤池、砂滤可基本达到排放标准更多还原

【Abstract】 Abstract This paper mainly compares the treatment effects and operational stability of UASB and hybrid anaerobic reactor treating wastewater of Chinese traditional medical drugs preparation in a full scale study. Also a submerged oxic biofilter followed to explore a complete and high efficient wastewater treatment process. The results show that when the influent COD Cr was between 3 800 to 15 320 mg/L, the COD Cr levels of effluent averaged 649 mg/L and 1 313.3mg/L for hybrid reactor and UASB respectively. When the volume load was 4 56 to 18 38 kgCOD Cr /m 3·d,average removal rate of COD Cr was 90.8%. When the submerged oxic biofilter and sand filter followed, the effluent could meet the discharge standard.更多还原
