【摘要】 针对上海城市发展中面临的污泥处理处置和城市土壤质量难以满足园林植物生长需要的两大难题,选择城市生活污泥应用于上海城市绿地,结果表明:城市绿地施用污泥后明显地促进园林植物生长,提高了城市绿地的生态景观效果;绿地施用污泥后土壤质量明显提高;绿地施用污泥虽然有重金属累积现象,但合理施用污泥不会造成绿地土壤重金属含量超标;对污泥产品的病原体定期监测也表明污泥腐熟后各项卫生指标符合国家相关标准,污泥在城市绿地中应用是安全的。城市生活污泥在城市绿地中应用不但能解决一部分污泥的出路问题,而且有利于城市土壤质量的提高和绿地生态景观效果的发挥。更多还原

【Abstract】 There are two tough things in Shanghai municipal development: one is sewage- sludge disposal, another is city soil quality that is unsatisfying the growth of gardening trees. We applied the typical municipal living sewage sludge on the Shanghai green area. The result showed that usage of sewage sludge improves the growth of gardening trees and increa(?)es the landscaping and ecological effect of the green area and the quality of soils. Although the amount of heavy metals is also slightly increased. it is not over the Standard of national limit. The periodical examination of pathogen on sewage sludge also showed that the sanitation index of sewage sludge satisfied with the related national Standard. So it is safe to utilize swage sludge on shanghai green area. As a result, the usage of swage sludge on green area can not only deal with some sewage sludge but also improve the soil quality and landscaping and ecological effect of green area.更多还原
