摘要
石家庄城市生活垃圾堆放场有3处,2005年全市生活垃圾产生量108万t,且呈逐年增加的趋势.在台头垃圾堆放场布置6个钻孔取样65件,进行了10项污染分析测试.结果表明：垃圾场周围场地土壤已经受到不同程度的污染,主要污染物有三氮、硫酸盐、砷、汞、氯离子,而且污染较严重,而六价铬、氰化物、酚有检出或含量较低;污染物质在场地3～6 m深度处富集,随着深度的增加、距离的增大,污染物含量减少、污染程度减弱.
There are three municipal solid waste dumping sites in Shijiazhuang.The total municipal solid waste output was 1.08 × 106 t in 2005,and it was still increasing yearly.Six boreholes were placed at Taitou solid waste dumping site,and 65 soil samples were collected to perform 10 pollution analysis tests.The results showed that soil at the solid waste dumping site has been subject to different degrees of pollution,and ammonia,nitrite and nitrate,sulfate,arsenic,mercury,and chloride ion are major pollutants with higher contents,while hexavalent chromium,cyanide,and phenol have lower contents.In addition,the pollutants occur mainly in the depth of 3 to 6 m,and the contents of pollutants and pollution level decrease with the increasing of depth and distance.
