| 摘 要： | 研究了上海市苏州河底泥中有机物及营养盐释放对上复水水质的影响,分析了微生物与底栖生物底泥再悬浮对底泥释放过程的影响。研究表明,底泥中化学需氧量与水体中的化学需氧量成正比,底泥中生化需氧量与水体中的生化需氧量呈正比,再悬浮促进底泥中污染物向上复水体释放。底泥SOD与水体中DO成正比,底泥污染是影响苏州河水质的重要因素;对苏州河底泥进行疏浚工程可较好地提高水体中溶解氧的浓度、降低化学需氧量、生化需氧量及氨氮的浓度。

| Abstract: | The influence of the organic materials and nutrition released from the sediment on the covering water quality of Suzhou creek in Shanghai was studied.The influence of microbacteria,oligochaeta and sediments subsuspending on pollutants releasing from the sediment was analysed.The results indicated that there was good relationship between COD of the sediments and water body,between BOD of the sediments and water body,between SOD and DO in the water body.The sediment sub-suspending promoted the pollutants releasing from the sediments.The sediments in Suzhou creek was an important factor to water quality.And sludge dredging was a good way to improve the DO and reduce the COD,BOD and NH_4-N in the covering water. |
