摘  要：
针对IC厌氧反应器现有结构形式的布水系统存在的主要问题及反应器钙化的困扰,文章拟在对比分析UASB与IC典型布置的基础上,对布水及重渣排放进行结构优化。提出一套由多层布水管道和倒锥形导流板组成的多层旋流布水与重渣排放系统。通过对该系统进行水力计算及重渣和生物污泥运动状态分析标明,该改进系统提高了布水均匀性并有效避免布水死区,使重渣与活性颗粒污泥经此完成筛选与分离,增强了废水中有机物与生物污泥的混合度,有效强化了传质和反应过程。最后文章结合对IC反应器进行改造的工程应用实例对该系统进行了实证分析。改造后反应器运行数据及红外热像检测表明改进方案取得了预计效果,这为IC厌氧反应器布水及重渣引起的反应器钙化等问题的研究提供了新的方法。

摘  要：
In view of the main structure problems existing in IC anaerobic reactor's water distribution system and the trouble of reactor calcification,this article focused on optimization design for the structure of water distribution system on the basis of comparison and analysis of UASB and IC typical layout. A multilayered cyclone water distribution and heavy sludge discharge system was proposed,which was composed of multi-layer water distribution pipe and inverted cone flow guide plate. Through hydraulic calculation of the system and motion analysis of biological sludge and heavy sludge,it was found that the uniformity of water distribution was improved,avoided water distribution dead zone,achieved the separation of heavy sludge from biological sludge,and enhanced the mixing degree of waste water organics with granular sludge. This effectively strengthened the mass transfer and reaction process. Finally,this article provided an empirical analysis based on a modified IC reactor project. The operation data and infrared thermography detection showed that the modified scheme achieved expected effect. Hence this provided a new method for solving the calcification problems caused by water distribution and heavy sludge discharge for IC anaerobic reactor.
