摘　　要：将污泥与秸秆进行混合好氧堆肥，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-composfing of sewage sludge and straw biomass, the temperature, moisture, pH and heavy metal forms in the mixture were studied. The results show that the temperature could reach 50 55℃ rapidly and lasted 5 d, suggesting that the conditions were able to fulfil the demand of sterilizing. pH changed between 7.5 ~ 9, moisture reduced during the eomposting process showed that the composting could be successfully processed. The effective form of heavy metal was decreased to reduce the environment harm of heavy metal pollution in the utilization of sewage sludge on land.
