| 中文摘要: |
| 采用了微电解-Fenton氧化-磷酸铵镁(MAP)沉淀联合处理垃圾渗滤液.试验结果表明:在HRT为80 min,pH为3.5时,微电解对垃圾渗滤液CODCr的去除率达到29.9%;微电解后的出水经Fenton进一步氧化,在pH为3,H2O2的投加量为13g/L,反应时间为25 min时,其CODCr的去除率可达81.3%;微电解-Fenton氧化后的出水再经MAP沉淀法处理,在pH为9,反应时间为25 min时,NH3-N的去除率达95%.微电解-Fenton氧化-MAP沉淀组合工艺处理垃圾渗滤液,其CODCr的总去除率达86.6%,NH3-N的总去除率达99.5%. |

| Micro electrolysis-Fenton oxidation-Magnesium Ammonium Phosphate(MAP) precipitation was applied to treat landfill leachates in this paper.The test results showed that 29.9% of COD_(Cr) from landfill leachates was removed by micro electrolysis at the HRT of 80min when pH is 3.5,81.3% of CODCr from the effluent from micro electrolysis was removed by Fenton oxidation at the reaction time of 25 min and H_2O_2 of 13 g/L when pH is 3,and that 99.5% of NH _4-N from the effluent from micro electrolysis-Fenton oxidation was removed by MAP precipitation at the reaction time of 25 min when pH is 9.The composite process of Micro electrol-Fenton oxidation-MAP precipitation could remove about 86.5% of COD_(Cr) and 99.5% of NH_3-N in the treatment of Landfill Leachates. |
