区域性饮用水的处理方法探讨

Discussing about the Treatment of Regional Drinking Water

文章根据所在地区水源水的特点,针对原水中存在的主要污染物,如硝酸盐、氯化物和氨氮等,利用介质过滤与膜法组合为主的处理工艺。结果表明该方法可以达到我国颁布的饮用净水水质标准(CJ94-2005)。该工艺对于特定的污染物显示出不同的特点,FA合金介质过滤对硝酸盐具有良好的去除率可达到90%;过滤组合净水设备氨氮去除率在90%以上;氯化物去除率较低;有机物指标降低。可以实现提升水质的目的,但存在稳定运行和维护问题。

According to the characteristic of native water, media filtration and membrane filtration treatment process were investigated in order to solve the main pollutant nitrate, chloride and ammonia nitrogen in the raw water. The results showed that these methods could reach the quality standards of drinking water （CJ94-2005）. There were different characters for the specific pollutants. The removal efficiency of nitrate was 90 % for media filtration of FA alloy and the removal efficiency of ammonia nitrogen was above 90 % for filtration combination water purifying plant. The removal efficiency of chloride was low and the indicators of organics decreased, which could reach the aim of upgrading the water quality. While there were problems with stable operation and maintenance.
