高速公路服务区污水资源化利用分析与建议

Analysis and Suggestions on Sewage Resource Utilization in Expressway Service Area

本文结合天津市气候条件及天津高速公路服务区污水资源化利用现状,对比各污水处理以及中水回用等处理技术优、缺点,提出适合天津高速公路服务区的污水处理技术——膜生物反应器(MBR)法。结合实际工程应用,污水经MBR处理后达到中水回用标准进行冲厕绿化,污水回用率可达70%。此应用表明MBR法具有较高的技术实用性、气候适应性、管理可控性和经济性,为后续天津市高速公路服务区污水资源化利用提供支持。

Combined with the climatic conditions and the current situation of sewage resource utilization of Tianjin Expressway Service area,comparing the advantages and disadvantages of various sewage treatment and reclaimed water reuse treatment technologies,membrane bioreactor(MBR) method suitable for sewage treatment in Tianjin Expressway Service area is proposed. Combined with practical engineering application,the sewage after MBR treatment meets the reclaimed water reuse standard and the wastewater reuse rate can reach 70%. This application shows that MBR method has high technical practicability,climate adaptability,management controllability and economy,which provides support for the subsequent wastewater resource utilization in Tianjin Expressway Service area.
