| 摘 要： | 通过对山东省济南市某城市污水处理厂所有处理单元的采样监测,分析研究了污水处理过程中CH4的释放通量。结果表明,该污水处理厂主要的CH4释放单元包括厌氧池、好氧池、缺氧池和二沉池,其中,厌氧池是最主要的CH4释放单元,释放量约占到全厂的50%。经测算,该污水处理厂每年释放CH4约12 600 kg,CH4的人均释放系数为31.5 g/(人.yr),每处理1 t污水释放CH4334.6 mg。COD浓度可能是影响厌氧池CH4产生和释放的重要因素,在实验监测范围内,高COD浓度可能会促进CH4的释放。 |

| Abstract: | Methane(CH4) emissions from all processing units were measured in a full-scale wastewater treatment plant in Jinan.The major sources of CH4 emissions were found to be the following units: anaerobic tanks,oxic tanks,anoxic tanks and secondary settlers.The most significant methane emissions occurred in anaerobic tanks,which accounted for over 50% of the total emissions of this plant.The total annual fluxes of CH4 emissions from the Jinan WWTP were 12 600 kg/yr,with the emission factors of per capita emissions of 31.5 g CH4/person·yr and flow-based emissions of 334.6 mg CH4/ton of wastewater.The most significant factor influencing methane emissions from anaerobic tanks might be COD concentration.High COD concentration could promote methane emissions. |
| Keywords: | greenhouse gas methane wastewater treatment plant flux |
