本文从水利水电砂石系统工程废水处理引入,分别介绍砂石料加工废水简易方案、自然沉淀方案以及“泥浆浓缩+脱水干化”方案,总结对比不同方案的区别和的特点,希望通过本文的研究能够更加全面的了解目前我国在水利水电砂石系统工程废水处理方面的具体情况,也为后期更好的选择废水处理方案提供参考。
This paper introduces from the waste water treatment of hydropower sand and gravel system engineering project, introduces the simple plan of sand and gravel processing wastewater, natural precipitation scheme and the plan of “slurry concentration + dehydration and desiccation” respectively, summarizes the differences and characteristics of different schemes, Of the research can more fully understand the current situation in China’s hydropower sand and gravel system engineering wastewater treatment of the specific circumstances, but also for the later better choice of wastewater treatment program to provide a reference.
