| Abstract: | 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. |
