摘　　要：基于微涡旋絮凝理论,开发出了利用水流动能自驱动的水力桨隔板絮凝反应器,并对比研究了其与传统网格絮凝反应器的絮凝沉淀效能,确定了水力桨隔板絮凝反应器的最佳结构和运行参数。结果表明:在同等条件下,水力桨隔板絮凝反应器的絮凝效果和稳定性均优于传统网格反应器,在最佳条件下,上清液浊度可达到3.0 NTU以下,水头损失较传统网格反应器降低40%以上。水力桨隔板絮凝反应器具有水力停留时间短、能耗低、抗冲击负荷能力强等优点,为净水厂升级改造提供了技术与理论支撑。A hydraulic impeller baffle flocculation reactor self-drived by the kinetic energy of water flow was developed based on the theory of micro vortex flocculation. The efficiency of flocculation and sedimentation of the developed reactor was compared with that of the traditional grid floeculation reactor, and the optimal structure and running parameters of the hydraulic impeller baffle flocculation reactor were determined. The results showed that under the same conditions, the effect and stability of the hydraulic impeller baffle flocculation reactor were superior to those of the traditional grid flocculation reactor, the supernatant turbidity could be below 3.0 NTU at the optimal operation condition, and the head loss was 40% lower than the traditional grid flocculation reactor. The hydraulic impeller baffle flocculation reactor has the advantages of short hydraulic retention time, low energy consumption, high resistance to impact load and so on, which can provide technical and theoretical support for upgrading and reconstruction of waterworks.
