摘要
通过调查分析和水质监测,研究了安顺市生活垃圾组成及填埋场渗滤液水质指标的变化,结果表明:安顺市垃圾填埋场的垃圾成分主要分为9大类。分别是煤渣、塑料、纸类、木材、玻璃、金属、有机物、布类和其它垃圾。煤渣是比重最大的成分。填埋场渗滤液经处理后其COD基本达标排放;pH在限值范围内;污水处理厂温度的高低与外界的气候变化相一致,进出污水处理场的渗滤液温度不变;污泥沉降比基本在正常值20%-30%内,污泥的沉降性能较好。总体看,垃圾填埋场对生活垃圾的无害化处置效果明显。
The garbage composition and the change of quality parameters of the leachate were investigated from the landfill of Anshun City in the present work. The results show that garbage consists of several categories, in- cluding cinder, plastic, paper, wood, glass, metals, organics, cloth and other rubbish. Cinder was the largest percentage of the garbage. The treated sewage discharged a high concentration of COD, whereas was still lower than the highest value 100 mg/L in GB (national standard), and the pH of sewage met the requirement of GB. The temperature change in sewage treatment plant was consistent with that of the outside, and the leachate tem- perature was stable from inflow to outflow. SV swings were from 20% to 30%, which satisfied the standard. Therefore, the landfill showed a significant efficiency on garbage treatment.
