摘要
采用生物活性炭滤-砂慢滤工艺对农村饮水处理进行了试验研究。试验结果表明,在原水为Ⅳ类水的情况下,生物炭滤-石英砂慢滤对水中CODMn和UV254的平均去除率分别为76.8%和68.8%,对NH3-N、NO3-N、TOC及浊度的平均去除率分别为91.6%、55.0%、45.2%和93.0%。生物炭滤-石英砂慢滤有望成为一种农村分散式饮水水质净化的新工艺。
Biological activated carbon filtration and slow sand filtration are used to study the rural potable water treatment.The results of the experiment show that for the raw water of Level Ⅳ,the average removal efficiencies of CODMn and UV254 can arrive at 76.8% and 68.8%,and those of NH3-N,NO3-N,TOC and turbidity are 91.6%,55.0%,45.2% and 93.0%,respectively.Therefore,it is hopeful that the technique can become a new kind of method for potable water purification in rural areas.
