微电解消毒工艺的影响因素研究

Study on the Factors Affecting Micro-electrolytic Disinfection Process

研究和探讨了微电解消毒饮用水工艺中Cl- 浓度和电解时间对消毒效果的影响规律和机理 ,认为微电解消毒的灭菌率与Cl- 浓度和电解时间的关系符合经验公式 :e =1.0 -exp(- 1.2× 10 4 c0 .5871×t1.6865) ,而电解产生的余氯具有持续消毒能力。为取得可靠的消毒效果 ,必须使待处理水中的氯离子浓度≥ 15mg/L、所需电解时间≥ 60s。

The effect of Cl - concentration and electrolytic period on the disinfection efficiency in the process of micro electrolytic disinfection of drinking water and relevant mechanism were discussed. It is believed that the sterilizing rate related to Cl - concentration and electrolytic period accords with the empirical formula: e = 1.0 - exp (-1.2 × 10 4 c 0.587 1 × t 1.686 5 ), and the residual chlorine produced by electrolytic process has the capability of sustained disinfection. In order to achieve reliable disinfection efficiency, Cl - concentration in the water to be treated should be ≥ 15 mg/L and the electrolytic period ≥60 s.
