Abstract This paper deals with wastewater treatment systems placed in motorway service areas (MSAs). In the years 2008-2009 eight of such facilities installed on the stretch of the A2 motorway between Poznań and Nowy Tomyśl were examined and analyzed. The system consists of a septic tank, a submerged aerated biofilter and an outflow filter. The volume of traffic on the highway was analyzed, the amount of water use was measured and peak factors were calculated. On this basis it was concluded that the inflows to the wastewater treatment systems in many cases exceeded the nominal design values. Based on the analysis of effluent quality it was found that the effects of plant operation in large part did not meet the requirements. It was found that the bioreactor aeration system and the design of the suspension separator (outflow filter) should be modified. One of the solutions was to use the soil-reed bed for wastewater treatment. The treatment of wastewater from the MSAs is a task that must take into account the unusual character of these facilities and the atypical quality of the effluent.

高速公路服务区废水的处理

摘要 本文介绍了高速公路服务区 (MSA) 中的废水处理系统。在 2008 年至 2009 年间，对安装在波兹南和 Nowy Tomyśl 之间的 A2 高速公路路段上的八个此类设施进行了检查和分析。该系统由化粪池、浸没曝气生物过滤器和流出过滤器组成。分析了高速公路上的交通量，测量了用水量并计算了峰值因子。在此基础上得出的结论是，在许多情况下，废水处理系统的流入量超过了标称设计值。通过对出水水质的分析，发现装置运行效果在很大程度上不符合要求。结果发现，生物反应器曝气系统和悬浮分离器（流出过滤器）的设计应该修改。解决方案之一是使用土壤芦苇床进行废水处理。来自 MSA 的废水处理是一项任务，必须考虑到这些设施的不同寻常的特性和出水的非典型质量。
