Abstract

For its special characteristics of water quality, the biological treatment technology for waste leachate and other special sewage is not yet mature. The study took advantage of the characteristics of the UASB reactor and improved the type of three-phase separator, in order to degrade organic pollutants in landfill leachate better .The results showed that Hydraulic loading was the main process control condition and had more obvious influence on the removal of COD with USAB. Whether hydraulic loading was too big or too small, the removal rate of COD with UASB reactor would decrease. When hydraulic loading is at 0.13 ~ 0.17 m3/m2•h, the removal rate of COD would reach the maximum and remain around 70%.Increased hydraulic loading would lead to a large number of accumulation of VFA, and make pH value decrease in the reactor. When the hydraulic loading increased from 0.11m3/m2•h to 0.25 m3 / m2•h, pH fell to 6.7 and VFAs rose to 0.4 g/L, the removal rate of COD would be reduced by 20%.
