对冬季填料床处理滇池流域污染河水进行了试验研究。结果表明:通过相关性分析可知,在2~6℃时,废砖块中微生物活性较低,温度回升后,微生物活性也随之增强;2~12℃时,废混凝土/沸石/煤渣组合生物量高,耗氧速率大且较为稳定,COD去除率保持在50%左右。降温期(5~12℃)时,废砖块对TN、NH4+-N和DTP去除率最高,平均可达64.5%、64.7%和69.7%;低温期(2~6℃)时,废混凝土/沸石/煤渣组合对NH4+-N、TN的去除率能达到56.4%~75.1%、56.5%~63.0%,大石子/小石子/煤渣组合削减DTP负荷量达到了2.1 g/(m2.d)。废砖块和大石子/小石子/煤渣组合分别适合在低负荷和高负荷下运行。综上所述,在整个试验过程中(2~12℃),废混凝...

Research on performance of packing media beds for treating polluted river water of Dianchi Watershed was conducted in winter. The result shows that according to the correlation analysis, the microbial activity in brick-based system（BS） is relatively low when the temperature is in the range of 2 - 6℃ , but it will be promoted as the temperature gradually rises. At 2 -12℃ , waste concrete/zeolite/cinder-based system（CZCS） , where its COD removal efficiency is about 50% , has a stable and high biomass level and the high level of oxygen uptak...
