滨州市滨城区地下水超采综合治理方案与成效

Comprehensive Treatment Scheme and Effect of Groundwater Over-extraction in Bincheng District, Binzhou

摘要:

滨州市滨城区地下水超采问题日益严重,实施系统性治理是实现区域水资源可持续利用的关键举措。文章基于“雨洪资源置换-水系连通优化-机井封存管控”的治理思路,以付家河片区引水工程、胜利河-兰家二干渠水系连通工程、西沙河-兰家四干渠水系连通工程及深层承压水井封存工程为四项核心工程,系统分析了滨城区地下水超采综合治理方案和实践成效。结果表明,工程实施后年可压采深层地下水170万m3左右,有效缓解滨城区地下水超采压力,为同类超采区治理提供了可复制的工程范式。

Abstract:

The problem of groundwater over-extraction is becoming increasingly severe in Bincheng District, Binzhou and the implementation of systematic treatment has become a key measure to realize the sustainable utilization of regional water resources. Based on the treatment idea of rainfall and flood resource replacement-water system connectivity optimization-sealing and management of motor-pumped wells, this paper takes four core projects including the Fujia River water diversion project, Shengli River-Lanjia Second Main Canal water system connectivity project, West Shahe River-Lanjia Fourth Main Canal water system connectivity project and deep confined water well sealing project, and systematically analyzes the comprehensive treatment scheme and practical effects of groundwater over-extraction in Bincheng District. The results show that the implementation of the projects can reduce the annual exploitation of deep groundwater by about 1.7 million m3, effectively mitigate the pressure of groundwater over-extraction in Bincheng District, and provide a replicable engineering model for the treatment of similar over-exploitation areas.
