摘要
实验拟对青岛市地铁北站填埋场封场10年的矿化垃圾模拟自然降雨,研究不同粒径及有机质含量的矿化垃圾污染物释放规律.结果表明,粒径小的矿化垃圾其溶出污染物浓度较高;有机质含量的差异与渗沥液污染物浓度之间没有明显的相关性(COD除外).污染物释放规律符合乘幂衰减模型,Cl-浓度变化趋势整体不符合乘幂衰减模型,但降雨后期符合.矿化垃圾在自然降雨作用下对水体环境存在一定的影响,且氨氮和TN是污染指数较高的因子.
Simulation of natural rainfall experiments is taken out to characterize the regularity of pollutants released from aged-refuse in Qingdao subway station landfill, which was closed down 10 years ago. Landfill aged-refuse with different particle sizes and organic matters are analyzed to compare the different release regularity of pollutants. Some conclusions are drawn as follows, the pollutants concentration released from small particle size of aged-re- fuse are higher than those from large particles. There is no obvious correlation between dif- ferent organic matter content and the pollutants concentration, except COD. The regularity of pollutants dissolution meets power function attenuation model. Chloride concentration changing trend does not meet the power function attenuation model overall, but it meets the model at the later period of simulation. Under the action of natural rainfalls, the aquatic environments are influenced by aged-refuse, and ammonia nitrogen and total nitrogen are the factors with high pollution indexes.
