摘　　要：采用自行研发的好氧动态发酵系统对城市污水处理厂的脱水污泥进行处理,研究了污泥好氧发酵处理过程中温度、含水率、供氧量等参数的变化规律。结果表明,污泥好氧发酵过程可以实现顺利升温并在55℃以上维持48 h,有效地降低了物料的含水率,去除了病原菌、寄生虫卵和大肠杆菌,达到了污泥减量化、稳定化、无害化、资源化的目的。A sludge digestion technology with dynamic aerobic fermentation was used to treat dewatered sludge in a Shanghai wastewater treatment plant. The variation of temperature, water content, air supply during the treatment was researched. The results show that the aerobic sludge fermentation can achieve successful temperature rise with maintenance of 48 h at 55℃, reduce water content and remove pathogen, parasite eggs and coliform. The sludge reduction, stabilization, innocuity, reclamation and reuse are realized.
