摘　　要：将污泥与秸秆进行混合好氧堆肥研究，对堆肥过程中堆料的温度、pH值、含水率及堆肥前后重金属各形态的变化进行了分析．结果表明堆肥处理可以实现顺利升温并在50-55℃维持5d以上，达到杀灭致病菌要求的条件；pH值稳定在7．5-9．0之间，含水率不断减小，堆肥过程可以顺利进行；重金属有效态有一定程度的降低，减小了污泥土地利用时重金属的环境危害。In Aerobic co-composting of sewage sludge and straw biomass, the temperature ,moisture ,pH and heavy metal forms in the mixture were studied. The results showed that the temperature could reach 50-55℃ rapidly and lasted 5 days to make able to fulfil the demand of sterilizing ; pH changed between 7.5-9.0 and moisture reduced during the composting process to make the composting process successfully; the effective form of heavy metal was decreased to reduce the environment harm of heavy metal pollution in the sludge utilization on land.
