摘　　要：介绍了微涡流混凝工艺的核心-涡流反应器的特点及其微涡流凝聚与立体接触絮凝的混凝反应机理。同时介绍了它在上海宝钢某污水回用处理工程中的应用情况:设计时调整澄清池进水装置及部分内部结构,增大反应室体积,在反应室中加入涡流反应器,沉淀区加设斜管。经1年多运行,效果显著,涡流澄清池处理规模增大/水力负荷增大,澄清池出水浊度稳定在3NTU以下,经V型滤池过滤后出水浊度小于1NTU,涡流吨水投资在35元以下。The micro-whirling coagulation process is the key to the whirling clarification technique. The micro-whirling reactor and its working mechanism which is whirling-coagulation and contact-flocculation are illustrated. Also the application on clarification tank in one wastewater reuse plant of BAOSTEEL was introduced. After being alteration to the standard clarification tank which is put the micro-whirling reactor into the first and second flocculation area and put the inclined pipes into the sedimentation area, the treatment scale of the whirling clarification tank is increased, the effluent turbidity of the tank is lower than 3 NTU, the effluent turbidity of finished water is lower than 1 NTU and the investment of per ton micro-whirling water is lower 35 yuan RMB.
