粉煤灰钝化污泥对土中总氮·总磷和重金属含量的影响
Effect of Sewage Sludge Stabilized by Fly Ash on TN,TP and Heavy Metals in Soil
摘要
Abstract
[Objective] The research aimed to investigate the effects of sewage sludge stabilized by fly ash on TN, TP and heavy metals in soil.[ Method] 1% and 3% sewage sludge stabilized by fly ash was added to the soil. [Result] Sewage sludge increased the amount of TN and TP in soil with the extent of 6.74% ~ 30.29% and 3.81% ~ 32. 67% respectively, while fly ash had no obvious effect on it. Sewage sludge increased the amount of Cu, Zn, Pb, Ni and Cr in soil. The passivation of fly ash to Ni and Pb was obvious in the treatment of 3% sewage sludge, while fly ash was no obvious effect on heavy metals in the treatment of 1 % sewage sludge. [ Conclusion] Sewage sludge increased the amount of TN and TP in soil, respectively while fly ash had no obvious effect. Sewage sludge increased the amount of heavy metals in soil, and the passivation of fly ash to Ni and Pb was obvious in the treatment of 3% sewage sludge.关键词
