  • 摘要: 将底泥有机物原地稳定化处理技术中药剂投加法和帽封法结合，研究以煤渣为帽封材料，苏州河底泥中分别投加零价铁（Fe0）及硝酸钙的实验里各体系上覆水体及底泥的pH、氧化还原电位（Eh）、有机含量在60 d的变化情况。结果表明，煤渣帽封下，底泥中投加Fe0或硝酸钙后上覆水体pH均在8左右，Eh呈下降趋势，投加Fe0后对上覆水体COD的影响较硝酸钙小，但均不会对上覆水体水质产生持久、较大的影响。从底泥有机质的去除率上来看，Fe0-煤渣帽封体系在反应周期里有机质的去除率约55%，而硝酸钙-煤渣帽封体系底泥有机质的去除率在27%左右。以Fe0-煤渣帽封材料复合体系运用在底泥原地稳定化帽封技术中降解有机物更为合适。
    Abstract: In the study on in-situ sediment treatment of organic pollutants from Suzhou Creck, chemical agents and cinder capping were applied. Combined with cinder capping, zero valent iron (Fe0) and calcium nitrate were used into the sediment of Suzhou Creck for 60 days for in-situ sediment treatment for organic pollutants. The effects of chemical agents with the capping material on the overlying water and sediment were investigated, including pH, Eh and COD factors. The results showed that with the add of Fe0 or calcium nitrate, the pH value raised to 8, while Eh value descended. Meanwhile, the effect on COD in overlying water by adding Fe0 was smaller than that by adding calcium nitrate, however, this effect on overlying water quality was not permanent or seriouse. According to the removal rate of COD from sediment, the removal rate in Fe0-cinder system was about 55%, while the removal rate of calcium nitrate -cinder system was around 27%. In this case, the system of Fe0 capped with cinder was more suitable to degrade organic pollutants in the in-situ sediment treatment.
