摘要
研究以厌氧颗粒污泥接种的复合式厌氧折流板反应器（HABR）启动：在HABR中直接接种厌氧颗粒污泥，以退浆废水为试验进水，在系统水力停留时间为168h，中温（32±1）℃，进水pH值6．5～8，碱度适当偏高条件下，进入反应器废水COD浓度由1800mg／L逐渐提高到13520mg／L，运行60d后系统COD去除率最低为45％，并且保持稳定，出水pH值和碱度相对比较稳定，污泥明显呈颗粒状，反应器启动完成。反应器可以在短时间内重新启动，污泥活性很快得到恢复。
Start-up of hybrid anaerobic baffled reactor（HABR） inoculated with anaerobic granular sludge has been studied. The wastewater was treated under mesophilic condition after anaerobic granular sludge was inoculated in the HABR, the pH of influent was 6.5 - 8 and alkalinity was suitably higher. Hydraulic retention time （HRT） was 168 h and the influent COD concentration was increased from 1 800 mg/L to 13 520 mg/L gradually during the experiment. The experimental results indicated that the lowest removal of COD was 45% and the pH and alkalinity of effluent were relatively stable. At the same time sludge appeared obviously granulation, the start-up was successfully finished. HABR can be restarted-up in a short time and the activities of anaerobic granular sludge can be restored quickly.
