摘要：

根据湘江水源水的特点,采用臭氧-生物沸石的除污染组合工艺进行处理试验。试验结果表明:生物膜形成前,系统对原水中的COD_Mn和NH3-N最高去除率可达43.1%和93.4%,生物膜成熟后在投加臭氧质量浓度为2.2mg/L,氧化接触时间为15min,水力负荷为2.3m/h时,工艺对COD_Mn、氨氮的去除率分别为53.6%和86.1%。

Abstract:

According to the characteristics of the raw water of Xiangjiang River， the experiment on pollutant removal by the combined process of ozone （O₃） and biological zeolite has been conducted. The results of the experiment aiming at the influent water quality show that before the biological film is formed， the highest removal rates of COD_Mn and ammonia-nitrogen reach 43.1% and 93.4%， respectively. After the film is matured， and when the ozone dosage is about 2.2 mg/L， oxidation contact time 15 min， and hydraulic load about 2.3 m/h， the removal rates of COD_Mn and ammonia-nitrogen by this process are 53.6% and 86.1% ， respectively.

Key words: slight pollution raw water, ozone, biological zeolite
