- Abstract:
- Scientific and reasonable zoning of drinking water source protection areas can reduce the cost of drinking water pollution treatment to the minimum. Based on detailed analysis of hydrogeological conditions of Xiamen Lianhua Reservoir, a two-dimensional water quality model was established by combining local topography, hydrology, ecological red line and social and economic requirements of the local water source and using discrete finite element method. MIKE21 and ArcGIS were employed as the test platforms to simulate and analyze the diffusion of pollutants in drinking water source protection areas, and the first-level protection area was determined to be 18.02 km2 , the second-level protection area was 48.4 km2, the quasi-protected area was 90.36 km2 and the total protected area was 156.78 km2. According to the Technical Guideline for Delineating Source Water Protection Areas (HJ 338-2018) and revision of water quality influence factors of the water source in the current region, future water quality changes in the divided region were predicted to provide reference for sustainable and healthy development of drinking water resources of Lianhua Reservoir.
