摘 要：
通过小麦大田试验,探讨城镇污泥在不同施用条件下对麦地农田土壤理化指标、土壤肥力和重金属含量的影响。结果表明,施用处理后的城镇污泥之后,土壤中有机质、全N、有效P、速效K的含量都得到了提升,土壤容重降低,持水性增强,理化性质得以改善。虽然施用污泥会向土壤中引入重金属,但在严格控制污泥自身重金属含量的情况下施用,依据土壤环境质量标准评估,其对土壤生态环境损害的风险较低。

摘 要：
The effects of urban sludge on soil physical and chemical index, soil fertility and heavy metal content in wheat field were studied in this experiment. The results showed that, after the application of urban sludge, the contents of organic matter, total N, available P and available K were increased in the soil, with the bulk density of the soil reduced, the water holding capacity of the soil strengthened, and the physical and chemical properties of the soil improved. Although the application of sludge will introduce heavy metals into the soil, but under the strict control of the heavy metal content of sludge itself, it can be considered that the risk to the soil ecological environment is low, according to the soil environmental quality standards.
