采用悬挂链曝气式接触氧化工艺在3个时段内处理城市河道污水,通过采用磷脂法、TTC-脱氢酶活性法和MPN法研究载体表面生物膜特性,来验证装置的水质净化效果。结果表明,进水水质变化幅度较大的时段1内,水质对缺氧区和好氧区内生物膜量及活性有很大冲击,对污染物的去除效果影响不大,COD、NH+4-N、TN和TP的平均去除率分别达到75.9%、80.8%、64.6%和78.3%;进水水质稳定的时段2内,缺氧区和好氧区内生物膜量和活性要高于其他时段,COD、NH+4-N、TN和TP的平均去除率分别达到77.0%、80.6%、69.4%和55.3%;低温运行的时段3内,缺氧区和好氧区内生物膜量和活性都低于其他时段,水质净化效果明显下降,COD、NH+4-...

The suspended chain aerating contact oxidation process was adopted to treat urban river sewage in three periods, and a study was conducted on the characteristics of biofilms on carrier surfaces by phospholipid method, TTC-dehydrogenase activity method and MPN method, in order to verify the water purification effect of the unit. The results show that in Period 1 with significant changes of the inflow water quality, the water quality has a great impact on the mass and activity of biofilms in the anoxic zone and the aerobic zone, but has little influence on the pollutant removal effect, and the a...
