【摘要】 为研究高锰酸盐-生物活性炭联用工艺对水质变化的适应能力,以某地表水体为研究对象,测试该联用工艺抗有机物和氨氮冲击负荷的能力.结果表明,高锰酸盐与生物活性炭联用工艺分别对常规饮用水处理工艺的混凝工艺和过滤工艺进行了强化,缩短过滤工艺达到稳定出水水质的时间,有效提高整体工艺的抗冲击负荷能力.当原水受到污染时,在生物活性炭工艺前增加曝气装置,提高生物工艺进水溶解氧含量,是一种提高生物活性炭工艺处理效能的简单高效方法.更多还原

【Abstract】 The effect of strong shock resistant capacity of the combined process of PPC preoxidation and BAC filtration was investigated in the treatment of surface water.The compared experimental results show that the organics removal rate in coagulation process and filtration process is enhanced and the steady running period in filtration process is shortened,which suggests that the combined processes of PPC preoxidation and biological activated carbon filtration have higher strong shock resistant capacity for organic matters and ammonia variation.In the case that raw water is polluted seriously,adding aeration process before biofilter process is an easy and effective way to enhance the biological process for organics removal.更多还原
