三淅高速路线跨越淇河、丹江河,临近丹江口水库,穿越西峡县大鲵省级自然保护区,水环境极其敏感。为此,三淅高速实施了生态边沟和生态种植槽等路面径流净化措施、桥面径流净化及事故应急措施、服务区污水资源化工程。根据测算,工程运营后,每年可以节约水资源18.40万t,减少COD排放324.73t,减少SS排放257.20t,减少氨氮排放16.35t,减少石油类排放401.08kg。
The Sanqian Expressway crosses the Qihe and Danjianghe Rivers, near the Danjiangkou Reservoir and passes through the Xiongxia Provincial Nature Reserve in Xixia County. The water environment is extremely sensitive. To this end, Sanyang high-speed implementation of the ecological side ditches and ecological planting tank runoff purification measures such as surface runoff purification and accident emergency measures, service area sewage recycling project. According to estimates, after the project operation, it can save 180,400 tons of water resources per year, reduce 324.73 tons of COD, reduce 257.20 tons of SS, reduce 16.35 tons of ammonia and 401.08kg of petroleum.
