摘要
通过常规处理预臭氧化和预氯化中试,对比研究了两种预氧化工艺对浊度、有机物、氨氮及消毒副产物前体物的去除效果。结果表明,预臭氧化后砂滤池出水中浊度平均值小于0.1 NTU,CODMn、UV254、TOC平均去除率分别为50.70%、84.60%、85.22%,去除效果明显优于预氯化。预臭氧化能有效去除消毒副产物前体物,氯消毒后CHCl3浓度为0.17μg/L,约为无预处理时的1/7,而预氯化会增加消毒副产物的生成量。
By pilot scale study, the effects of pre- ozonation and pre- chlorination before conventional water purification were compared by examination of turbidity, ammonia nitrogen, organic contamination and THMFP in the output water of filtration. The results showed that with ozonation pre - treatment, the average turbidity was below 0.1NTU in the output water of filtration, the average removal ratio of CODMn＇ UV254, TOC were 50.70 % ,84.60 % and 85.22 %, these were better than pre - chlorination. Pre - ozonation course could remove huge of THMFP in the raw water, the concentration of CHC13 was 1/7 of that when there was not pretreatment, but pre - chlorination would produce more THMs.
