摘要
于2004年6月对白洋淀底泥进行了调查采样.化学分析的结果表明,底泥中氮、磷、有机质含量较高.重金属铜、锌、镉、铅呈现出不同程度的污染.通过原状土柱试验探讨了底泥在较长时间里发生的物质转变和演化规律,土柱内不同的pH值、C/N、灌水量对底泥演化的影响.结果表明,在pH值为7.3、C/N为12:1、灌水量为80L条件下处理有利于芦苇对底泥的无害化处理.
The chemical analysis results of sediment sampled and investigated in June of 2004 in Baiyangdian Lake showed that the contents of N, P and organic matters were high relatively in the sediment; and there appeared pollution of different degrees on the heavy metals of Cu, Zn, Cd and Pb. Through original soil column experiment, the regularity of material transformation and evolution of sediment during a relatively long period and the influence of different pH value, C/N and the amount of water irrigated on sediment evolution were explored. The treatment under the condition of pH 7.3, C/N 12:1 and irrigated water amount 80L was beneficial to the harmless disposal of sediment by reed.
