臭氧-生物沸石处理湘江微污染原水试验研究

Study on the Treatment of Micro-Polluted Raw Water from Xiangjiang River by Ozone-Biological Zeolite Processes

根据湘江水源水的特点,进行了臭氧-生物沸石的除污染组合工艺试验。试验结果表明,最优臭氧投加量为2.2mg/L左右,氧化接触时间为15min,水力负荷为2.3m/h左右。此时该工艺CODMn、氨氮的去除率平均分别为53.6%和86.1%,从而为微污染源水处理提供了一种新的方法。

According to the characteristics of Xiangjiang River, the experiment which raw water treatmented by the combination processes of ozone（O3）with biological zeolite was conducted. The results show that the optimal dosage of ozone was 2.2 mg/L, contact oxidation time was 15 min and hydraulic loading was 2.3 m/h. Under this condition, the removal effieiencies of CODMn and ammonia nitrogen were 53.6 % and 86.1%, which was proved as a new measure to treat micro - polluted raw water.
