复合式厌氧折流板反应器处理垃圾渗滤液

采用复合式厌氧折流板反应器对垃圾渗滤液的处理工艺进行研究，主要考察了温度、水力停留时间(HRT)、进水氨氮质量浓度对反应器处理效率的单因素影响.结果表明，当温度由30℃降到10℃时，化学需氧量(COD)去除率下降了49.11%;随着HRT的缩短，系统容积负荷逐渐提高，COD去除率呈下降趋势;当进水氨氮质量浓度逐渐升高，反应器对COD的去除能力大幅度下降.利用响应曲面法得出最优参数:当温度为34.97℃，HRT为46.54h时，COD去除率最高，达到88.57%.

Landfill Leachate Treated Using Hybrid Anaerobic Baffled Reactor(HABR)

The disposal process of landfill leachate using hybrid anaerobic baffled reactor(HABR)was investigated to study the effect of temperature， HRT(hydraulic retention time) and ammonia concentration of inflow-water on reactor efficiency. The results showed that the chemical oxygen demand(COD)removal rate decreases by 49.11% when the temperature dropped from 30℃ to 10℃. With the shortening of HRT， the volume load increases gradually and the removal rate of COD shows a downward trend. When the influent concentration of ammonia nitrogen gradually increases， the removal capacity of COD in the reactor greatly decreases. Using the response surface method to get the optimal parameters showed that the removal rate of COD reaches the highest when the temperature is 34.97℃ and the HRT is 46.54h， the removal rate peaks at 88.57%.
