【摘要】 进行了利用陶粒生物滤池工艺低温生物预处理黄河微污染水的研究,结果表明,温度的降低对陶粒生物滤池去除CODMn、UV254和氨氮的影响不明显,其平均去除率分别为11%、22.2%和61.2%。水温低于5℃时出水中亚硝酸氮浓度升高。此外,低水温条件下陶粒上生物膜脱氢酶活性仍然较高。更多还原

【Abstract】 Research on Yellow River water treatment using bio-ceramic filter was conducted. The decline of water temperature show no obvious effect on COD_ Mn, UV_ 254 and ammonia removal and their removal efficiencies were 11%,22.2% and 61.2% respectively. The effluent nitrite concentration rose below 5 ℃. Moreover, biofilm activity was still high even at low temperature.更多还原
