摘要:
 为研究洪湖底泥生产有机肥的可行性，对洪湖底泥的有机质、营养物质和重金属含量进行检测分析。研究表明：洪湖底泥有机质平均含量为10.5%，为中度污染；全氮含量为4026 mg/kg，为重度污染；全磷含量为1632 mg/kg，为中度污染。此外，洪湖底泥中重金属汞（Hg）、铅（Pb）、镉（Cd）、铬（Cr）的含量平均值均低于有机肥限量标准，但砷（As）的含量略高于限量标准。全湖范围内Hg、Pb、Cd、Cr、As单因子污染指数Pi均≤1，为无污染状态。南、北部湖区重金属的内梅罗综合污染指数P值分别为0.81、0.80，处于尚清洁状态。以上结果表明洪湖底泥是作为有机肥料的良好资源。
Abstract:
 To investigate the feasibility of producing organic fertilizer from the lakebed sludge of Honghu Lake, the organic matter, nutrients, and heavy metals contents of the sludge collected at Honghu Lake were detected and analyzed. The results showed that the average content of organic matter was 10.5%, which indicated a moderate pollution state. The content of total nitrogen (TN) was 4026 mg/kg, which indicated a severe pollution state. The content of total phosphorus (TP) was 1632 mg/kg, which indicated a moderate pollution state. In addition, the average contents of heavy metals mercury (Hg), lead (Pb), cadmium (Cd), and chromium (Cr) in the lakebed sludge were all lower than the limit standards of organic fertilizer. But the content of arsenic (As) was slightly higher than limit standards. The single-factor pollution index (Pi) of Hg, Pb, Cd, Cr, and as in the whole lake were all ≤1, which was defined as a pollution-free state. The Nemero index (P) of comprehensive pollution of heavy metals in the southern and northern lake areas were 0.81 and 0.80, respectively, which were in a clean state. Based on the above analysis, it is determined that the lakebed sludge of Honghu Lake was a good resource for producing organic fertilizer.
