摘要 通过研究给出城市污泥堆肥营养物质及重金属成分,分析了大田作物(水稻、冬小麦、玉米、棉花)、果树、草坪肥料施用情况。研究结果:城市污泥作为可再生资源与我国农业发展具有互补性,正确看待重金属问题,因地制宜制定满足需求的施用标准对于污泥堆肥行业的发展具有重要意义。 Based on the research, nutrient and heavy metal compositions in domestic sludge compost were given, and its application as a fertilizer in planting of field crop (such as paddy rice, winter wheat, corn, cotton), fruit trees and lawn were analysed. It has been found that the domestic sludge as renewable resources could play a complementary role in the agricultural development in China. To the development of sludge composting industry, it would be of significance to take a correct attitude towards the problem of heavy metals contained in the domestic sludge, and to work out an application standard as needed in line with local conditions.
