【摘要】 取相同年限等距离的不同输送管路铸铁管、复合管材输送出的自来水水样各3组,利用燃烧氧化——非分散红外吸收法测定水中总有机碳含量,并以此为依据分析自来水在净化处理后经过不同管路输送对水中有机物含量的影响。试验结果表明,不同输送管路对水中总有机碳的含量有着很大的影响。铸铁管路比复合管路对自来水的二次污染更为严重一些,应当在选择水体输送管路时尽量避免铸铁管。更多还原

【Abstract】 Take three groups water samples from different transmission pipeline.Then utilize combustion oxidation-non-dispersive infrared absorption to detect the contect of TOC of watcr,and take the results as a basic of analysic the influence on the contect of TOC from different transmission aftet purification.The resuts showed that,there is a great impact on the contect of TOC of water from different transmission pipeline.And cast iron pipes has more sreious secondary pollution than composite pipes.So we should avoid cast iorm when chosing transmission pipeline.更多还原
