摘要:
以长江原水为研究对象，通过四种生物活性滤池处理单元对长江水源水中微污染物的去除效果进行对比研究。结果显示生物强化滤池I和II对NH3-N、NO2--N、CODMn、UV254和BDOC的平均去除率分别为80.0%和85.2%、95.4%和95.4%、25.0%和26.2%、12.0%和12.0%、68.3%和70.0%，生物强化滤池II的去除率稍高于生物强化滤池I，但差异无显著性（p > 0.05）。生物活性炭滤池I和Ⅱ对NH3-N、NO2--N、CODMn、UV254和BDOC的平均去除率分别为84.2%和89.4%、95.4%和95.4%、24.0%和31.2%、16.0%和16.0%、67.9%和72.0%，其中生物活性炭滤池II对NH3-N、CODMn和BDOC的去除率高于生物活性炭滤池I（p >Taking the raw water of Yangtze Riveras the research object, micro-pollutant removal efficiencies of biofilters for the river water were investigated. The results showed that the average removal rate of NH3-N、NO2--N、CODMn、UV254 and BDOC was 80.0%, 95.4%, 25.0%, 12.0% and 68.3% in the biologically-enhanced active filter type I, and 85.2%, 95.4%, 26.2%, 12.0% and 70.0% in the biologically-enhanced active filter type II. The rates in the biologically-enhanced active filter type II were not significantly higher than those in the biologically-enhanced active filter type I（p > 0.05）.The average removal rates of NH3-N, NO2-N, CODMn, UV254 and BDOC by the biological activated carbon filter type I were 84.2%, 95.4%, 24.0%, 16.0% and 67.9%, respectively; The average removal rates of them by the biological activated carbon filter type II were 89.4%, 95.4%, 31.2%, 16.0% and 72.0%, respectively. The removal rates NH3-N, CODMn and BDOC by the biological activated carbon filter type II were significantly higher than those by the biological activated carbon filter type I. The content of organic material with low MW took great part in Yangzi River, in which the proportion of the organics with MW
