CRWS-mountain Project:Coordinate remediation techniques and devices for water-soil pollution in mountain areas in China

摘要

Rural environmental governance is an important strategy to achieve the goal of building"green liveable villages"in China.However,studies on technology and devices for pollution remediation focus mainly on urban areas;in this regard,few studies have focused on rural areas,especially mountainous or hilly areas with interflow.Coordinate remediation techniques and devices for water-soil restoration in mountain areas(CRWS-mountain),a subproject of the"environmental monitoring and remediation in rural areas"project(ERM-rural project),was undertaken to develop techniques and devices for coordinating the restoration of water and soil in rural mountainous and hilly areas with interflow.The CRWS-mountain project will attempt to explore the mechanisms of pollutant transportation and transformation in the interflow-soil-surface water system,establish in-situ and heterotopic remediation systems in landfill,towns and surrounding areas,and construct a comprehensive system for"polluted soilinterflow-surface water"by integrating all the technologies and devices at Yanting,a typical rural mountainous hilly area in Sichuan,Southwest China.We expect that after using this comprehensive system,the water quality will meet the requirements for local water function zoning.The operation cost is 10%lower than that of the existing urban equipment.
