| 中文摘要 |
| 研究填充床酸化反应器及其与UASB甲烷化反应器组成的二相厌氧消化系统的运行特性。填充床酸化反应器启动方便,酸化速率高、抗水力冲击和pH波动的能力强、COD容积负荷达200kg/(m3·d).采用预调碱工艺,二相消化系统运行正常,可高效地处理酿酒废水。在进料COD浓度1000-7000mg/L、COD负荷40kg/(m3·d)时,出料COD浓度小于200mg/L.对抗生素生产废水也有较好的处理效果。 |
| 英文摘要 |
| In this work the operation characters of the two-phase anaerobic digestion system incorporated by a packed bed acidification reactor and an UASB methanorization reactor were studied.The packed bed acidification reactor started up easily and possesed of a high acidification rate and a good resistence against hydraulic impulsion and pH fluctuation.The COD volume charge was higher than 200 kg/(m3·d). Adopting a preadjusting alkality technology,the two-phase system could operate normally and effectively for treating brewing wastewater.Under the conditions of COD concentration 1000—7000 mg/L in the feed and COD charge 40 kg/(m3·d), the COD concentration was less than 200 mg/L in the effluent. The system possesed also a rather good capacity for treating antibiotics wastewater. |
