摘要
将城市污水处理厂污泥分别与生石灰、粉煤灰、黏土按质量2∶1混合后填埋,研究各填埋柱渗滤液的pH、SS、CODCr、BOD5、总氮、氨氮、总磷、Na+、K+、Mg2+、Ca2+的变化规律。结果表明添加剂能够显著改变污泥的物理性质,而且渗滤液性质及污泥中污染物迁移转化行为也与添加剂有密切关系。
Three blended sludges produced from sewage sludge adding quicklime,fly coalash and clay according to the ratio of sewage sludge additives at 2∶1 were landfilled. Study was made on properties of each landfill column leachate , including pH ,SS, CODCr , BOD5 , TN, NH3-N, TP, Na+, K+, Mg2+,Ca2+. Results ,showed that additives could obviously change sludge's physical properties,and leachate and convective change of pollutants in sludge also have close relationship with additives.
