| 摘 要： | 为开展高效厌氧生物技术处理家禽粪便的应用研究,试验依据固定床厌氧反应器(anaerobic pecked bed reac-tor)的特点,设计了一个有效容积为20 L的高效厌氧反应器,以猪粪尿为发酵原料,进水COD浓度范围在4 820~54 000mg/L,实验过程为55 d。按进料的水力停留时间可将实验划分为2个阶段:前期(44 d)和后期(11 d),前期通过提高进料浓度直接提高反应器处理浓度,水力停留时间保持为2 d,每7~8 d为一个周期;后期通过缩短水力停留时间间接提高反应器处理浓度,进料浓度保持不变,每2~3 d为一个周期。通过对厌氧处理系统运行过程中COD、pH、挥发性成分、TN、TP和NH3-N含量的测定,分析了该系统运行特点。结果表明:在发酵的第1~55 d,整个厌氧处理系统能够稳定运行,COD去除率稳定在67%~88%之间;对TN、TP、NH3-N都有很好的去除能力。

| Abstract: | In order to research on a highly-effective disposal of poultry manure through anaerobic biotechnology,an efficient anaerobic reactor with an effective volume of 20 L was designed according to the characteristics of anaerobic pecked bed reactor.Pen manure as raw material for fermentation,the raw water COD was adjusted between 4 820 and 54 000 mg/L.The whole process was 55 days,which was divided into two stages according to the raw of hydraulic retention time: the prophase(44 d) and the anaphase(11 d),in the ... |
