随着斜板(管)沉淀技术的发展和多层匀质滤料的采用,使给水净化工艺中的沉淀、过滤速度大大提高。这就对混凝反应的结絮质量、适应能力、稳定性提出更高要求。然而,目前混凝反应设备变革较少,构筑物庞大。以某水厂为例,其反应池容积约1320米~3,而同向流斜板沉淀池容积仅为850米~3,形成“头重脚轻”的不协调状态。为此,进行高效能反应器的研究成为当前共同关心的问题。据报道,荷兰发明了一种波形板填料式竖流水力反应装置。以较优的水力条件达到
With the development of sloping plate (tube) precipitation technology and the adoption of multi-layered and homogeneous filter media, the precipitation and filtration speed in the water purification process is greatly improved. This puts forward higher requirements on the quality, adaptability and stability of the coagulation reaction flocculation. However, at present, there are few changes in the coagulation reaction equipment and the structures are huge. Taking a water plant as an example, the reaction tank volume is about 1320 m~3, while the co-current flow swash plate sedimentation tank volume is only 850 m~3, forming a “top-heavy” and inconsistent state. For this reason, research on high-performance reactors has become a common concern. According to reports, the Netherlands has invented a corrugated plate-type vertical hydraulic reactor. Achieved with better hydraulic conditions
