摘　　要：填埋处理是我国城市生活垃圾处理的主要方式,填埋产生的渗滤液被认为是其周边地区地表水及地下水的潜在污染源。对垃圾填埋场产生的渗滤液特征的分析及其变化规律的研究是垃圾填埋场环境污染控制的重要内容。本研究分50%、60%、70%、80%四个梯度调节填埋垃圾初始水分,在常温下进行6个月的填埋,填埋后每月定期测定渗滤液CODcr、pH、氨氮。研究表明,填埋垃圾的初始水分为60%～80%比较适宜垃圾降解,渗滤液CODcr、氨氮降解速度较快、降解效果也相对较好、pH接近中性或呈中性。Landfill is the main form of municipal solid waste disposal in our country,whose leachate is regarded as potential source of pollution to the surface water and groundwater in its surrounding areas. The research on the characteristic and development patterns of leachate generated by municipal solid waste landfill is the essential content in its pollution control. This research analyzes the process from adjusting the initial moisture of waste by scales of 50%,60%,70% and 80% to monthly test of the COD,pH and ammonia nitrogen of leachate after six months＇landfill under normal atmospheric temperature. The research reveals that 60% to 80% of initial moisture is the most suitable for municipal solid waste degradation,in which leachate COD and ammonia nitrogen degrades fastest and most efficiently and pH solution is mostly close to neutral.
