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。
Based on the theory of micro-vortex swirling flocculation, a hydraulic propeller plate flocculation reactor self-driven by water flow kinetic energy was developed and its flocculation and sedimentation efficiency compared with the conventional grid flocculation reactor was studied. The flocculation reaction The best structure and operating parameters of the device. The results show that under the same conditions, the flocculation efficiency and stability of the hydraulic paddle flocculation reactor are better than those of the traditional grid reactor. Under optimal conditions, the turbidity of the supernatant can reach below 3.0 NTU, Traditional grid reactors have been reduced by more than 40%. The hydraulic paddle plate flocculation reactor has the advantages of short hydraulic retention time, low energy consumption, strong anti-impact load capacity and provides technical and theoretical support for the upgrading of the water purification plant.
