Studying on subsurface infiltration system for wastewater disposal of freeway subrange

摘要

It's significant to find a wastewater disposal technology with low cost, good effect and easier operation in Chinese freeway subranges. Based on generalizing the technologies of wastewater disposal in freeway subranges, this paper discussed how to apply the subsurface infiltration system for wastewater disposal in a freeway subrange. Comparing with conventional wastewater disposal system, the subsurface infiltration system can save 40% cost in a lifecycle of a freeway subrange.
