| 摘 要： | 以厦门市筼筜污水处理厂的脱水干化污泥作为有机肥种植马尼拉草,通过盆栽试验,探讨污泥直接施用对马尼拉草生长和产量的影响及重金属在马尼拉草-土壤间的迁移转化和积累情况.结果表明,污泥中氮、磷、钾和有机质含量丰富,重金属含量均低于城镇污水处理厂污泥处置园林绿化用泥质的标准（GB/T23486—2009）;施用适量污泥可促进马...

| Abstract: | Manilagrass was planted with direct application of dewatered and dried municipal sewage sludge collected from Xiamen Yundang Wastewater Treatment Plant under pot experiment.The effect of sludge application on the growth and yield of Manilagrass was determined,and the transfer and accumulation of heavy metals in the Manilagrass-soil system was discussed.The results showed that the sludge was rich in nitrogen,phosphorus,potassium and organic matter,and the contents of heavy metals studied were all lower than ... |
