摘要:

氧化还原电位(ORP)是判断液相体系氧化还原能力的综合参数,反映了液相体系的氧化还原倾向。探讨了温度、时间、pH、溶解氧等因素对ORP的影响,总结了ORP指标在水环境污染防控中的应用,指出了ORP应用过程中应注意的事项。就目前应用而言,ORP在给水处理、循环水处理、脱硫废水处理、水处理设备防腐等方面具有很好的应用前景。此外,ORP在湿地保护方面的应用也是新的发展方向。

Abstract:

Oxidation reduction potential(ORP) is a comprehensive parameter for judging the redox ability of liquid phase system, which reflects the redox tendency of liquid phase system. This paper analyzes the effects of temperature, time, pH, dissolved oxygen and other factors on ORP. The applications of ORP index in the water environmental pollution prevention and control are summarized, and the matters needing attention in the application of ORP are pointed out. As far as the current application is concerned, ORP has good application prospects in water treatment, circulating water treatment, desulfurization wastewater treatment, and anti-corrosion treatment of water treatment equipment. In addition, the application of ORP in the wetland protection is also a new development direction.

Key words: oxidation reduction potential(ORP), redox reaction, water treatment
