鸡粪堆肥处理对重金属形态的影响

In high-temperature and aerobic condition,speciation of heavy metals were studied during composting process of chicken manure and maize straw.The results showed that total weight of composting material was reduced and content of heavy metals was increased during composting process.No significant changes were found in total amount of heavy metals during composting process.The speciation of heavy metals could be affected significantly by composting.Ni and Cd's percentages of Fe-Mn oxides fraction increased by...
