| 摘 要： | 对比城市污泥和堆肥处理,两组试验导致土壤耕层中的重金属总量和有效态含量与对照相比均有明显增加。比较重金属总量的浓度系数(K)c和有效态重金属浓度系数可看出,堆肥及配合石灰处理的土壤,以及配合化学肥料处理的土壤影响有效态重金属Cd、Cu、Ni、Pb和Zn的Kc较对重金属总量Kc影响大。施用城市污泥及其堆肥的不同处理土壤表现为轻度污染(Zc<10.0)。 |
| 关 键 词： | 城市污泥堆肥 重金属 污染 |

| Abstract: | Compared with the control, the total heavy metal content and absorbable metals increased obviously in municipal sludge or compose treated soil. Concluded by concentration coefficient (Kc) of total heavy metal content and available metal content, Kc of Cd, Cu, Ni, Pb and Zn increased after application of compost, compost and lime or compost and chemical fertilizer. The soil applied with different content of municipal sludge and compost showed light pollution(Zc<10.0). |
| Keywords: | compost originated from municipal sewage sludge heavy metal pollution |
