| 摘 要： | 利用瓦氏呼吸仪测定了矿化垃圾浸出液的微生物耗氧量,探讨了矿化垃圾粒径分布与其浸出液可生化性的相关性,结果表明:不同粒径范围矿化垃圾浸出液的可生化性存在显著差异,其可生化性的难易程度与粒径分布呈正相关,即大粒径范围矿化垃圾浸出液可生化性较好.通过对同一粒径范围的矿化垃圾浸出液在不同稀释倍数、不同pH条件下的生化呼吸线与內源呼吸线的对比,发现随着浸出液稀释倍数的降低其可生化性得到提高,且在中性条件(pH=7.0)下可生化性最好,酸性条件(pH=6.2)下次之,碱性条件(pH=9.0)下最差.

| Abstract: | The correlation between the distribution of aged refuse and biodegradability of the leachate was studied by determining biological oxygen demands using Warburg breathing equipment,which can indicate the biodegradability of the leachate.The results showed that:(1)the biodegradability of the leachate from different particle size aged refuse has a significant difference;the level of biodegradability is positively correlated with the size distribution,which namely the biodegradability from large-size is better.... |
