摘要:

介绍了城市污泥的性质并结合肥料市场信息分析了污泥农用存在的若干问题,即:有害物质的负面影响;养分含量低、施用成本高、肥效慢;运输和施用不方便;市场布局不合理。提出了相应的对策,即:堆肥化处理提高污泥稳定性;对城市污泥堆肥进行深加工;利用污泥堆肥进行土壤生物控氮;开拓污泥堆肥的新市场。

Abstract:

Factors, limiting the agricultural use of sewage sludge (SS), were analyzed by introducing the properties of SS, combined with the market information of fertilizers. The factors including environmental risks of contaminants in SS, low nutrient content, high cost during transport and fertilization and the immature market status. The following countermeasures are suggested: using composting technique to stabilize SS; deep-processing; using SS as an agent that control soil nitrogen loss, and developing new market for SS.
