摘要: IC厌氧反应器是新一代污水处理的高效反应器，设计的关键是如何使罐体内形成均匀稳定的内循环流动，其性能受控于布水器的布水结构、布孔方式、进水流速等。现有布水器结构复杂，加工难度较大，成本较高，同时还存在排泥死角问题。针对该情况，对IC厌氧反应器的布水结构进行优化设计，并在对反应器内气-液-固三相流流场进行大量三维非稳定流数值分析的基础上，确定适宜的上升流速及布水器进水口尺寸，并加工组装实体模型进行模型实验验证，结果表明优化的布水器结构有效可行。

Abstract: The crux of internal circulation (IC) anaerobic reactors,a new,highly efficient means of treating wastewater,is the achievement of a uniform and stable internal circulation. Their performance is determined by the water distribution system,arrangement of holes,flow rates,etc. Because of the complex structures in this apparatus,the water distribution process is difficult,increasing costs. Moreover,the treatment of mud presents problems. To improve the function of the traditional IC anaerobic reactors,a structure-optimized design and numerical analysis method for gas-liquid-solid flow fields have been studied. The appropriate flow rate and inlet sizes have been determined,and a hydraulic model test had been performed. The results show that the optimization of the water distribution structure is effective and feasible.
