低温低浊有机微污染水源水臭氧预氧化的效能研究
|
摘要
寒冷地区地表水水质具有低温低浊及有机微污染的水质特点,该特点成为提高此类水源水净化效能的瓶颈,传统的常规处理工艺难以适应。以寒冷地区有机微污染的地表水为研究对象,采用臭氧预氧化强化传统处理工艺,使出水符合《生活饮用水卫生标准》(GB 5749-2006)的要求。研究结果显示:在低温低浊条件下,臭氧预氧化能有效去除浊度、COD_(Mn)、UV_(245)、TOC,当臭氧投加量为1.0mg/L时,系统对浊度、COD_(Mn)、UV_(254)及TOC的去除率达到最大,分别为97.76%、50.53%、67.92%及53.25%。
Considering the characteristics of low temperature,low turbidity and organic micropollutant of the surface water in cold area,which becomes the critical problem of improving the source water purification efficiency and it is difficult for the conventional process to dispose.In order to guarantee the quality to meet the requirements of Standardsfordrinkingwaterquality(GB 5749-2006),studying on the object of cold area surface water,adopting preozonation for enhanced conventional process was applied on the water treatment.The results of pilot-scale study showed that preozonation could improve the removal efficiency of organic matter under the condition of low temperature and low turbidity.When ozone dosage was 1.0mg/L,the removal rate of turbidity,COD_(Mn),UV_(254) and TOC were 97.76%,50.53%,67.92% and 53.25%,respectively.
