| 摘 要： | 针对试验设计的两相厌氧反应器(TPAD)进行启动研究，寻求快速启动的方法. 试验采用人工配水，以淀粉、葡萄糖作为主要碳源. 采用低负荷启动方式，快速提高进水ρ(CODCr)，缩短水力停留时间(HRT)，使产酸相尽快维持在酸性最佳条件下. 间歇投加粉末状CaO调节产酸相出水pH在7.0±0.3，从而保证产甲烷相在最佳条件下. 经过36 d的启动过程，在产酸反应器和产甲烷反应器中均出现了性能良好的厌氧颗粒污泥. 启动后第36天，当两相厌氧反应器的水力停留时间(HRT)为17.03 h，CODCr负荷(VLR)为8.46 kg/(m3·d)，水力负荷为0.059 m3/(m2·h)时，系统整体CODCr去除率达到最优，为96.66%.

| Abstract: | The start-up of two-phase anaerobic reactor (TPAD) designed for experiment were investigated, so to seek the rapid start-up method. Glucose and starch were used as the organic-carbon source of the synthetic wastewater in the experiment. Starting up at low organic loading, the influent CODCr was increased quickly and HRT was shortened by stages, so that acidogenic phase could work inacidic optimal condition as soon as quickly. Pulverous CaO was added intermittentlyinto acidogenic phase to keep the effluent pH 7.0±0.3, so that methanogenic phase could work in optimal condition. After 36 days of operation, good performance anaerobic granular sludge was respectively appeared in acidogenic reactor and methanogenic one. On the 36th day, two-phase anaerobic system was achieved optimal CODCr removal efficiency (96.66%) at HRT of 17.03 h and VLR of 8.46 kg/(m3·d) and hydraulic surface loading of 0.059 m3/(m2·h). |
