摘要
污泥中有机质和N、P等养分含量较高,污泥的土地利用是污泥处置的主要方式之一。结合国内外最新研究进展,分别从磷组分、磷有效性、磷的累积、迁移和土壤生物学性质方面概括了污泥农用对土壤磷的影响,阐述了污泥与磷肥混施后磷的肥效状况,为污泥的资源化利用提供参考。
Sewage sludge contains a considerable amount of nutrient such as C/N/P and trace elements, land application of sewage sludge will be one of the important disposal alternatives. This paper summarized application of sewage sludge effecting on soil phosphorus, combining the latest research achievements at home and abroad about P in soil, the paper reviewed that the effect of sewage sludge on the composition and availability of P in soil, the accumulation and leaching of P, the microbial properties and soil enzymes, the result of sewage sludge combined with water-soluble inorganic P is also summarized. The purpose of this paper is to offer the information for the most economical sludge disposal method.
