摘    要:试验系统利用某城市污水厂生产工艺回流污泥为系统悬浮污泥,探讨了悬浮填料投配比、投配方式和中试硝化效果之间的关系。试验结果表明,悬浮填料最小投配比为15%即可满足系统硝化功能的要求;悬浮填料的投配方式宜采用集中投配并布置于曝气池的末端,这样既可提高系统的生物膜量,又有利于硝化反应的实现。而且,控制适当的溶解氧浓度,悬浮填料的投加有助于同步硝化反硝化更充分的进行。

关 键 词:悬浮填料  试验研究  同步硝化反硝化  优化  城市污水厂  溶解氧浓度  悬浮污泥  回流污泥  生产工艺  试验系统  试验结果  生物膜量  硝化反应  可满足  曝气池  配比  配方  中试

Abstract:The relation among adding ratio and adding mode of suspended media as well as the system's nitrification was discussed by a pilot scale experiment with on-site process return sludge as its suspended sludge. Experimental results showed that 15% of the minimal adding ration of suspended media can satisfy the requirement of nitrification, and centralized adding mode is layout to the tail end of aeration tank for the purpose of en-hancing biofilm quantity and nitrificaiton. Moreover, controlling DO to a suitable concentration, the addition of suspended media is helpful to improve synchronous nitrification-denitrification.
Keywords:suspended media  adding ratio  adding mode  nitri-ficaiton  synchronous denitrification
