摘　　要：研究采用静态强制通气堆对氧化塘底泥进行堆肥处理,对堆肥过程中氮、磷和重金属的变化规律进行了研究。试验结果表明:总氮下降了17.5%,总磷上升了47.0%,重金属略有上升,堆肥时间以7周为宜。The oxidation pond sludge was composted and changing process of nitrogen, phosphorus and heavy metals contents during the composting was studied. Results showed that content of TN reduced by 17.5%, TP increased by 47.0% and heavy metals also increased. The feasible time of compost of oxidation pond sludge is about 7 weeks.
