摘要
经过一次换水周期的连续池水监测,表明采用机械循环过滤池水COD含量低于人工沉淀吸污方法,二种净化方法COD含量比较有显著区别,P<0.05。单纯采用液氯消毒池水pH值偏酸性,均值为5.85,与采用漂白粉消毒的池水pH值比较差异非常显著,P<0.01。开放后两池水均受到CHCl_3污染,最高检出值分别为92.8μg/L和172.8μg/L,CHCl_3污染与池水使用时间、池水耗氧量均呈正相关。
From continuous observation and analysis of pool warer between the cyeles of ehanging water, the results showed that if the authors adopt the maobinery oiroulation to filter water,COD of water is lower than that of artifioial drawing of preoipitated dirt. When the authors compare the two ways of water purification, Theg find that the COD values of water are greatly different, P<0. 05. When liguid chlorine is used to disinfect the water, pH of water tends to be acid, its average value is 5.85 whioh is greatly different with that using bleaohing powder to disinfeot water. (P<0.01). After using Chiorine to disinfect pool water, it will be contammated by CHCl3. The amount of CHCL3 production is in direct proportion to the length of the time of utilization of pool water and COD of water.
