臭氧组合工艺冬季处理黄河水的研究

Ozonation-combined Process for Treating Yellow River Water During Winter

冬季条件下生物预处理、常规处理及深度处理组合工艺处理黄河水的研究结果表明,在原水水质较好的情况下,组合工艺对高锰酸钾指数、DOC、UV254、色度、浊度和氨氮的平均去除率分别为38.6%、40.1%、58.3%、60.5%、86.4%和74.8%。此外,组合工艺对总藻也有较高的去除率。组合工艺对磷有很好的去除效果,能把可溶性磷浓度控制在0.01mg/L以下。

Experimental investigation was conducted to treat polluted raw water from the Yellow River at a water works in Zhengzhou City during winter season, featuring use of biological pretreatment and ozonation. Removal efficiencies are evaluated in terms of parameters such as COD_(mn), dissolved organic carbon (DOC), UV254, colority, turbidity and ammonium.
