- 摘要:
- 土地利用是资源化利用城市污水厂污泥的有效途径, 污泥中含有丰富的氮、磷、钾和有机质等肥力成分, 随污泥中的营养成分一起进入土壤的还有其中的重金属。污泥和污泥堆肥的土地施用可以促进植物的生长、提高作物的产量以及明显改善土壤的物理和生物学性质。然而污泥中的重金属元素是限制其大规模农田利用的重要因素。污泥和施污土壤中重金属形态的研究可以用来评价土壤中重金属的生物有效性以及它们在土壤中的移动性。
- Abstract:
- Land application is one of the important disposals for resource reuse of sewage sludge .With humus and nutrientssuch as nitrogen, phosphorus, potassium and micronutrients, heavy metals of sewage sludg e entry the soil when sewagesludge was applied to land.Sludge and its compost application on land can promo te the plants growth, raise the g rain output,as well as improve soil physical and biological properties apparently .However , heavy metals contained in sludge is an impo rtantconfined factor to sludge applicatio n on agricultural land on a large scale.The investigation of speciation of metals bothin sludge and in sludge-amended soil may help to assess the bio-availability of metal fractions and the possibility of mobilizationof these metals in soil.
