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NH_3-N含黾的测定,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、NH_3-N都有很好的去除能力.

In order to research on a highly-effective disposal of poultry manure through anaerobic biotech-nology, an efficient anaerobic reactor with an effective volume of 20 L was designed according to the characteris-tics of anaerobic pecked bed reactor. Pen manure as raw material for fermentation, the raw water COD was adjus-ted between 4 820 and 54 000 mg/L. The whole process was 55 days, which was divided into two stages accord-ing to the raw of hydraulic retention time: the prophase (44 d) and the anaphase (11 d) ,in the prophase the dealing concentration of reactor was directly advanced by increasing the raw water concentration, the hydraulic remain time ( HRT) was maintained 2 days, 7 ～8 days per cycle. In the anaphase, the dealing concentration of reactor was indirectly advanced by shortening the residence time, and the influent concentration was unchanged, 2～3 days per cycle. COD, pH, volatile components and the content of TN,TP and NH_3-N were determined through to the whole procession in the anaerobic treatment system, and analysis of operating characteristics of the system. Results demonstrated that in the fermentation section 1～55 d, the whole system could be stably opera-ted, with a stable COD removal efficiency which were between 67% and 88% ; and high capacity in removing TN ,TP and NH_3-N.
