| 摘 要： | 高温堆肥后污泥的土地利用可充分发挥资源化、无害化的优势，污泥土地利用防止重金属污染一直是污泥施用中最重要的问题。通过测验发芽率指数这一代表植物毒性的指标证明，通过在污泥堆肥中加入粉煤灰、磷矿粉和草炭等不同的改性剂或重金属钝化剂可大大降低堆肥的植物毒性，从而降低污泥中重金属的可利用性。

| Abstract: | Sewage sludge through high temperature compost used as fertilizer can make it resourceable and harmless, but the major draw back of sewage sludge composting is the high heavy metal content in the end product. It is therefore the aim of the present study to develop germinate rate index representing toxicity to plant to prove that, adding different passivation reagents such as fly ash, phosphorate rock, zeolite to sewage sludge compost can reduce toxicity to plant remarkably, thus reduce the heavy mental availability. |
