摘　　要：综述了我国中水深度处理工艺的发展历程、相关工艺在国内电厂的主要研究与应用情况及其主要问题与控制策略。石灰混凝法是热电厂中水回用的第二代处理工艺,应用广泛;双膜法及全膜法具有更高的污染物去除效率,已成为目前热电厂中水回用的主流深度处理工艺。膜污染是膜法深度处理工艺的限制因素,膜污染形成机制与控制策略研究成为中水回用领域的研究热点和难点。随着水处理技术及设备的发展,一些新型的材料、技术和设备也逐渐推广应用于热电厂的中水深度处理;未来城市中水将成为热电厂的第一水源,膜法将成为中水深度处理与回用的最关键工艺,其预处理和深度处理工艺将实现多样化与高效化的发展。The development of advanced treatment technology for reclaimed water reuse, their application status in thermal power generation plants in China, and the limitations and controlling strategies for these technologies are reviewed. Lime coagulation was the 2nd generation reclaimed water treatment technology, which has been widely applied. Membrane technology becomes the mainstream technology for reclaimed wastewater reuse due to its excellent performance. Membrane fouling is the limiting factor for membrane processes, therefore the membrane fouling issue and its control strategies are becoming the research focus. With the development of water treatment technology and equipment, new-type advanced treatment processes as well as new technologies, materials have been applied in the reclaimed water treatment. The reclaimed water would be the first option for thermal power generation plants in the future, and dual-membrane technology will be the key advanced treatment technology, with the pretreatment and advanced treatment technologies developed efficiently.
