Abstract: 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%.
