摘　　要：介绍了改良UNITANK工艺在诸暨污水厂二期扩建工程中的设计及应用情况,这种工艺的改进主要体现在运行方式、增加内回流和加装填料等方面。推荐采用机械曝气方式,相关经济分析显示使用复叶液下曝气搅拌两用机的投资少、调控灵活、运行费用低。工程实际运行结果表明,该工艺出水水质好,运行费用低,能广泛适用于小型城市污水处理。The design and application of the modified UNITANK process in second-stage extension project of Zhuji WWTP were introduced. The modification of the process is reflected in operation mode, increase of internal reeireulation and adding carriers. The mechanical aeration mode is recommended. The relevant economic analysis indicates that the muhiblade submerged mixed aerator has characteristics of low investment, flexible regulation and control and low operation cost, The operation result shows that the process has good effluent quality and low operation cost, and can be widely used in wastewater treatment of small cities.
