| Abstract: | The leachate from a Hong Kong landfill, containing 15.70 g/L of chemical oxygen demand(COD) and 2.26 g/L of ammonia nitrogen (NH3-N), was first treated in a UASB (upflow anaerobicsludge blanket) reactor at 37 ℃. The process on average removed 90.4% of COD with 6. 6 days ofhydraulic retention at an organic loading rate of 2. 37 g/(L · day) COD. The UASB effluent wasfurther treated by the Fenton coagulation process using H2O2 and Fe2+. Under the optimal condition of200 mg/L H2O2 and 300 mg/L Fe2+ and initial pH 6.0, 70% of residual COD in the UASB effluentwas removed, of which 56% was removed by coagulation/precipitation and only 14% by free radicaloxidation. It is obvious that H2O2 and Fe2+ had a strong synergistic effect on coagulation. The averageCOD in the final effluent was 447 mg/L. Removing each gram of COD required 0. 18 g of H2O2 and0.28 g of Fe2+, the Fenton coagulation process was discussed in this paper. |
