【摘要】：目的了解上海市家用活性炭净水器出水有机物指标合格状况及其影响因素。方法分别于2011年夏季(7月)、秋季(10月)、冬季(12月),对上海市248户使用活性炭净水器的居民家庭净水器的使用情况进行调查,并检测出水水样中耗氧量、总有机碳浓度。结果夏季、秋季和冬季的活性炭净水器出水中耗氧量的不合格率分别为37.5%,33.6%,37.9%;夏季活性炭净水器出水中总有机碳的不合格率为0.8%,秋季和冬季活性炭净水器出水中的总有机碳均合格。多因素分析显示,夏、秋、冬季不同主滤芯出水量与净水器出水耗氧量不合格呈正向关联。各个季节活性炭净水器出水中耗氧量与总有机碳均呈正向关联。结论家用活性炭净水器在使用过程中存在有机物去除率不达标的问题,有一定的健康风险。影响耗氧量合格率的因素主要为主滤芯出水量、市政水水源地,应及时更换活性炭滤芯。
[Abstract]:Objective to investigate the quality and influencing factors of organic matter in the effluent of household activated carbon purifier in Shanghai. Methods in summer (July), autumn (October) and winter (December), 248 households using activated carbon water purifier in Shanghai were investigated, and oxygen consumption and total organic carbon concentration in water samples were detected. Results the unqualified rate of oxygen consumption of activated carbon purifier in summer, autumn and winter was 37.5 and 33.637.9, respectively, and the unqualified rate of total organic carbon in summer was 0.8, and the total organic carbon in autumn and winter was up to standard. Multivariate analysis showed that there was a positive correlation between the water output of different main filter elements and the effluent oxygen consumption of the water purifier in summer, autumn and winter. The oxygen consumption of activated carbon purifier in each season was positively correlated with total organic carbon. Conclusion the removal rate of organic matter in the household activated carbon water purifier is not up to the standard and there are some health risks. The main factors affecting the qualified rate of oxygen consumption are the water output of the filter core, and the activated carbon filter should be replaced in time for the municipal water source.
