摘要: 氧化还原电位(ORP)是影响地下渗滤系统稳定运行的主要因素之一,对系统内部微生境和污染物处理效果有重要影响。因此,就地下渗滤系统中ORP对有机物去除、脱氮、除磷和微生物活性的影响作用,目前常用的干湿交替、基质组配、布水管复氧、分流比、植物复氧、土壤动物活动复氧和通风管复氧等改善ORP措施进行了总结归纳,表明各种措施都有一定的工程适用性。随着工艺研究的深入,多种改善措施将组合应用,新型基质填料的研发将会促进地下渗滤系统理论内涵、拓宽工程实践应用,工艺运行将会更加灵活。

Abstract: Oxidation Reduction Potential (ORP) is one of the main factors that influence the operation of subsurface wastewater infiltration system (SWIS). It also has a crucially effect on treatment efficiency and the environment of microbial. This paper briefly describes the effects of ORP on organics removal, nitrogen and phosphorus removal and the microbial activity in the SWIS. Measures which are commonly used to improve ORP, such as flooding and drying alternate, constituting matrix, diffluent ratio, oxygen recovery by inflow pipes, roots of plants, soil animal activity and ventilation pipes, are analyzed. The analysis shows that all measures have the engineering applicability. With further research, a series of improvement measures will be applied in combination. The development of new matrix materials will enrich connotation of SWIS theory and broaden the application of engineering practice. Process operation will be more flexible.
