摘要
通过对北京中水处理设施的投资及运行状况进行调研,计算并分析了分别采用生物接触氧化工艺和生物转盘工艺时的运行成本和总成本;分析表明采用生物接触氧化工艺在中水处理中是比较经济的,而生物转盘工艺无论是初期投资还是长期运行,其费用都较高;通过分析与比较可为新建中水设施的工艺选择提供参考。
The status of different processes of reclaimed water treatment in Beijing was investigated. Aerobic submerged attached growth process and rotating biological contact process are compared in their operation cost and total cost in this article, and the result indicates that the aerobic submerged attached growth process is cheaper and should be widely used in new built reclaimed water treatment stations.
