目的研究一般水质处理器在模拟实际使用浸泡条件下有害物溶出情况。方法对一般水质处理器进行常规纯水静态浸泡试验、模拟市政供水静态浸泡试验和模拟市政供水动态浸泡试验的浸泡效果对比试验。结果模拟市政供水动态浸泡试验色度、浑浊度的增加值高于纯水静态浸泡和模拟市政供水静态试验,差异均有统计学意义(P<0.05);模拟市政供水静态和动态浸泡试验中耗氧量、铅含量的增加值均高于纯水静态浸泡试验,差异均有统计学意义(P<0.05)。纯水静态浸泡试验各指标均合格。模拟市政供水静态浸泡试验和动态浸泡试验耗氧量不合格,色度、浑浊度和铅均合格。结论一般水质处理器在模拟市政供水动态和静态浸泡试验中,耗氧量、铅、镉、砷、汞、六价铬、挥发酚的溶出量未见差异,但耗氧量和铅均明显高于纯水静态浸泡试验的溶出量。
Objective To study the dissolution of harmful substances in general water immersion condition by general water processor. Methods Conventional pure water static immersion test was carried out for the general water quality processor to simulate the soaking effect of municipal water supply static immersion test and simulated municipal water supply dynamic immersion test. Results The added value of dynamic test of municipal water supply for dynamic soaking test was higher than that of static test of pure water and simulated municipal water supply (P <0.05). Consumption of static and dynamic soaking test The oxygen and lead contents were higher than that of the pure water soaking test, the differences were statistically significant (P <0.05). Pure water static soaking test indicators are qualified. Simulated municipal water supply static immersion test and dynamic immersion test oxygen consumption failed, color, turbidity and lead are qualified. Conclusions The general water quality processor has no difference in oxygen consumption, lead, cadmium, arsenic, mercury, hexavalent chromium and volatile phenol in simulating municipal water supply dynamic and static soaking test, but the oxygen consumption and lead are significantly higher In pure water immersion test static dissolution.
