Biostyr~曝气生物滤池中试研究

为了确认Biostyr曝气生物滤池工艺在中国的适应性,在高碑店污水处理厂进行了中试。记录和总结了2002年1月至2003年10月间的试验结果。取高碑店污水处理厂3系列初沉池出水为试验用水,试验期间水温在9-29℃。试验经历经典硝化/反硝化和同时硝化/反硝化的运行模式。以GB18918-2002为准,Biostyr滤池出水中化学耗氧量、总悬浮固体、氨基态氮、总氮等污染物均可达到其一级B标准。

Pilot study of Biostyr in Gaobeidian Wastewater Treatment Plant

It is presented the process performance results obtained during the trials period from January 2002 to October 2003, which took place in Gaobeidian WWTP, Beijing, in order to confirm the technological feasibility of the Biostyr process. The influent entering the pilot process was the plant primary effluent (after the primary sedimentation tank). The temperature of the effluent in the pilot plant during the trial period was ranged from 9 to 29 degree Centigrade. Two schemes were conducted in the sequence of the classical nitrification/denitrification and the simultaneous nitrification/ denitrification. The trials have shown that all the Biostyr configurations produced an effluent compliant with the required consents on the basic control items of the Class I Standard B of the National discharge standard of water pollutants for municipal wastewater treatment plant (GB 18918-2002).
