摘　　要：针对火电厂中废水硬度普遍较高的特点,为采用合适的工艺技术来降低废水硬度,以适应后续工艺需要,本文从技术性能、系统设计、运行维护等方面,对比研究了石灰软化澄清+过滤、结晶造粒软化+固液分离工艺、一体式改良型诱晶软化这三种不同的除硬工艺,并分析上述工艺各自的优缺点,为电厂废水软化处理的工艺设计、设备选型提供方案。In view of the generally high hardness of waste water in thermal power plants,in order to adopt appropriate process technology to reduce the hardness of waste water to meet the needs of subsequent processes,this paper compares three different hardening processes,namely lime softening clarification+filtration,crystallization granulation softening+solid-liquid separation process,and integrated improved induced crystallization softening,from the aspects of technical performance,system design,operation and maintenance,and analyzes their respective advantages and disadvantages. It provides a scheme for process design and equipment selection of power plant wastewater softening treatment.
