饮用水深度处理工艺的对比研究

Study on Advanced Drinking Water Treatment Process

通过三种饮用水深度处理工艺的对比试验研究了不同工艺对同一源水的处理效果,从而提出较优的运行方案。结果表明:当原水的CODMn≥3.76mg/L时,为了确保最终出水符合《饮用净水水质标准》(CJ94-1999)的要求,采用两级臭氧氧化的臭氧生物活性炭的方式运行,其它情况下,从经济的角度建议按只投加预臭氧的方式运行。

Study on treatment effects of the same water source by different composite water treatment processes were carried out in this paper. The results showed that when CODMn of the raw water 〉3.76 mg/L, the pre- and post-ozonation with BAC process should be used in order that the treated water meet the requirement of CJ94-1999; by contraries,only pre-ozonation and BAC should be taken into consideration.
