摘    要:氧化塘污泥中含有较丰富的各种氮、磷养分,将氧化塘污泥堆肥处置后农用是一种有效的处置方式。采用静态强制通气堆对氧化塘底泥进行堆肥处理,时堆肥过程中氮磷的变化规律进行了研究。试验结果表明,堆肥过程中总氮含量下降了17.5%,总磷含量上升了47.0%,堆肥的时间以49d左右为宜。

关 键 词:氧化塘底泥  氮磷  堆肥处理

Abstract:There are abundant nitrogen and phosphorus in oxidation pond sludge, so land utilization of oxidation pond sludge after compost is an effective disposal approach. The changing process of nitrogen and phosphorus during the compost is studied. The result showed the content of TN reduced 17. 5% and the content of TP increased 47%. In addition, the feasible time of the compost of oxidation pond sludge is about seven weeks.
Keywords:oxidation pond sludge  nitrogen and phosphorus  compost treatment
