摘    要:实验测定生活垃圾填埋前生物稳定化预处理过程的相关指标,探讨生物稳定化处理对削减生活垃圾填埋污染的作用.结果表明:经44d两阶段(快速降解阶段+后腐熟阶段)生物稳定化处理后,生活垃圾重量减少约70%(湿重).生活垃圾中易降解有机组分明显减少,生物稳定性强的木质纤维素类约占有机物62%(干重);好氧呼吸速率(AT4)下降80%;填埋物的甲烷年排放估算值下降约80%.生活垃圾浸出液的化学需氧量(COD)和总有机碳(TOC)下降达90%以上;总氮(TN)和氨氮(NH4-N)最终质量浓度分别为峰值的60%和20%.说明经生物稳定化预处理后垃圾的填埋污染潜力明显下降.

关 键 词:生活垃圾  稳定化  预处理  填埋污染
