| 摘 要： | 城市污泥中含有大量的植物营养元素,其农业利用能改善土壤的理化性质,提高作物产量,减少污泥对环境的二次污染,从而实现污泥的资源化、无害化、稳定化和减量化处置目标。为此,以北方四大典型污水处理厂的污泥为对象,对其2007-2008年的污泥数据进行统计并分析污泥中的主要成分,与国家污泥农用标准比较,判别污泥农用的可行性并提出合理化建议,以期为北方地区污泥合理地利用提供科学依据,探索经济有效的适合城市污泥处置与利用的有效途径。

| Abstract: | Sewage sludge contains abundant plant nutrition,which could improve the physical and chemical character of the soil while applying sewage sludge into the crop land and increase the yields.Land application of sewage sludge not only avoiding the second pollution to the environment,also realizing the resourced,harmless,stabilization,and decreased disposal purpose.In this study,the sewage sludge from four typical wastewater treatment plants in north China is taken as the sample,the data of the sludge from 2007 ... |
