悬浮填料生物反应器去除有机污染物和氨氮的中试研究

Pilot Study on Simultaneous Removal of Organic Pollutants and Ammonium in Suspended Carrier Biological Reactor

对悬浮填料生物反应器进行了去除有机污染物和氨氮的中试研究 ,结果表明 ,当填料投加率为 5 0 %时 ,水力停留时间为 12h ,10h ,8h和 6h四个工况条件下 ,中试试验进水BOD597～2 35mg/L ,CODCr2 0 3～ 678 2mg/L ,NH3-N 17～ 31mg/L时 ,出水BOD5<15mg/L ,CODCr<10 0mg/L ,NH3-N

Organic pollutants and ammonium from Shanghai Petrochemical Company were treated in a pilot scale suspended carrier biological reactor. The results showed that at hydraulic retention time of 12, 10, 8 and 6 hours with 50% suspended carrier, the effluent concentrations of BOD 5, COD Cr and NH 3-N were less than 15mg/L, 100mg/L and 15mg/L respectively under the influent BOD 5, COD Cr , NH 3-N concentrations of 97～235mg/L, 203～678 2mg/L and 20～35mg/L respectively.
