The widespread application of conventional activated sludge treatment process has been employed to deal with a variety of municipal and industrial sewage. While the generation of waste activated sludge (WAS) was considerably huge, the management and disposal expenses were substantially costly. A promising process aimed for WAS reduction during the operation process is urgently needed. Thus, increasing attentions emphasizing on the improved or novel sludge reduction processes should be intensively recommended in the future. This review presents the current and emerging technologies for excess sludge minimization within the process of sewage treatment. The ultimate purpose of this paper is to guide or inspire researchers who are seeking feasible and promising technologies (or processes) to tackle the severe WAS problem.
传统的活性污泥处理工艺已被广泛应用于处理各种城市和工业污水。然而，废活性污泥（WAS）的产生量相当大，管理和处置费用也相当昂贵。因此，迫切需要在运行过程中减少 WAS 的处理工艺。因此，未来应加强对改进或新型污泥减量工艺的重视。本文综述了污水处理过程中剩余污泥减量化的现状和新兴技术。本文的最终目的是为寻求可行和有前途的技术（或工艺）来解决严重的 WAS 问题的研究人员提供指导或启发。
