| 摘 要： | 系统地研究了生物氧化、生物抑制和风力驱动准好氧填埋的生活垃圾卫生填埋场甲烷减排集成技术.研究表明,喷洒了NMS营养液(80 mL/kg)的矿化垃圾为甲烷氧化覆盖层,可以持续氧化甲烷,第23天后甲烷氧化率稳定在75%左右;当氯仿质量浓度为20 mg/kg或乙炔体积分数达到1.2%时,甲烷产量极少,产甲烷菌几乎被完全抑制;采用风帽技术的改进型准好氧填埋可以利用风速0.5 m/s的自然风,在不增加成本的前提下大幅减少甲烷排放.

| Abstract: | The integrated process combining bio-oxidation,bio-inhibition and wind-driven semi-aerobic landfill for the reduction and mitigation of methane in refuse landfill were studied.75% of methane bio-oxidation was found in aged-refuse reactor with nutrient dosage of 80 mL(per kg aged refuse). Methane production from refuse could be reduced when 20 mg of chloroform adding in one kg aged refuse or 1.2% acetylene was mixed with the refuse. The emission of methane could be reduced when a wind-driven cowl with the speed of 0.5 m/s was installed onto the landfill gas pipelines. |
