摘要
采用气浮和臭氧生物活性炭联用技术对太湖原水进行处理,结果表明在平均水温为25.7℃,臭氧接触时间为13.3min,HRT为15min时组合工艺对太湖水浊度、氨氮、CODMn、藻类和UV254的去除率分别为99.4%、98.3%、86.3%、97.9%和96.5%。并且ZJ-15型颗粒活性炭的去除性能总体上优于柱状颗粒活性炭。
The Taihu Lake raw water was treated with a combined technique of air flotation and ozone biological activated carbon. The results showed that the removal rates of turbidity, ammonia nitrogen, CODMh, algae, UV254 by combined process were 99.4%, 98.3%, 86.3%, 97.9% and 96.5%separately under the conditions of the average water temperature 25.7℃, the contact time of ozone 13.3 min and the HRT of the biological active carbon 15 min. And the ZJ-15 granular activated carbon were excelled over columnar granular activated carbon.
