曝气生物滤池陶粒滤料和火山岩滤料性能对比研究

摘要

仙女河污水处理厂采用曝气生物滤池工艺，本文对陶粒滤料与火山岩滤料进行了对比分析研究。分别从两种滤料对NH3-N、SS及COD等指标的去除效果及运行成本等方面进行了考察。结果表明陶粒及火山岩两种滤料均能满足设计要求，但从经济运行的方面来看，选择使用陶粒滤料会更加经济。%xiannvhe waste water treatment plant using biological aerated filter process, study of ceramsite and effusive rock, the re-moval efficiencies of COD, NH3-N、SS by the filtering materials and their Operating cost. The results show that both of the two kinds of filter materials can meet the design requirements , But from the view of economic operation, ceramsite is more economical, rational choice.
