山岭隧洞施工废水处理方法探讨

Probe into treatment processes of wastewater during tunnel constructions in mountain

山岭隧洞施工大多位于山区,且往往是河流源头或水源保护区上游,对排放水质有较严格的要求。施工过程中会产生大量含悬浮物的废水,如爆破、机械施工,还会产生含有一定量的氨氮和石油类废水。结合某工程实例,在考虑受纳水体的排放要求和山区环境特点的情况下,对山岭隧洞施工过程产生的各类废水进行分质分流处理,本着简单易行的原则,提出了有针对性的工艺技术路线,为山岭隧洞施工废水处理方案的选择提供参考。

Most of the tunnel constructions were carried out in the mountainous areas which are often the district of river source or water source conservation and have strict requirements for wastewater discharge. A great deal of wastewater containing SS would be produced in the tunnel constructions. In addition,if blasting and mechanical constructions are employed a certain amount of ammonia nitrogen and petroleum pollutants would be also produced. Based on a case, according to the discharge standard of receiving water and the characteristic of mountainous areas, wastewater during tunnel constructions was treated divided- qulity and divided- flow. In accordance with the principle of simple and easy operationa,particular technical route was proposed to provide guidance and reference for the treatment processes of wastewater during tunnel constructions in the mountain.
