| 摘 要： | 通过对城市污泥和矿区土壤成分分析,研究了施用城市污泥对矿区土壤环境的影响。结果表明,利用污泥中大量的N、P、K和有机质以及污泥较强的粘性、持水性和保水性等理化性质不仅可以提高矿区土壤的肥力、迅速恢复植被,而且可以改善土壤的结构,从而达到复恳的目的。 |

| Abstract: | Through municipal sewage sludge and soil composition analysis,application of municipal sludge soil environmental impact of the mining area was studied.Results showed that proposed use of sludge in a lot of nitrogen,phosphorus,potassium and organic matter use more viscous sludge,water holding capacity and retention,and other physical and chemical properties of municipal sludge to raise the fertility of the soil,vegetation restored,and can improve soil structure,so as to achieve the purpose of rehabilitation. |
| Keywords: | municipal sewage sludge heavy metals N P K abandoned mining area |
