摘　　要：剩余污泥减量技术众多,可分为在污水处理过程中靠强化分解代谢减少污泥量以及在污泥处理阶段通过脱水、消化、焚烧等手段减少污泥量两大类。首先,评价了目前应用与研究中的各种污泥减量技术;其次,介绍了欧盟国家目前以强化厌氧消化为目的的能量(甲烷)回收技术及其预处理技术;最后,展望了未来潜在的污水/污泥处理、减量技术——生物可降解塑料PHA的生产技术。There are various technologies for excess sludge reduction, which can be categorized as two main processes： （1） reducing produced sludge by enhancing catabolism during wastewater treatment; （2） reducing produced sludge by dewatering, digestion, incineration and so on during sludge treatment. The current applied and studied technologies for sludge reduction are first evaluated. The enhanced anaerobic digestion techniques towards producing more methane and the pretreatment technologies in EU countries are secondary introduced. Finally, a future potential wastewater and sludge treatment technology for production of PHA biodegradable plastics is prospected.
