Impacting of Polluted River on Groundwater Chemical Environment

Abstract:

The organic material, suspension material and colloid in water can be filtered when water permeates through the surface soil. The efficiency of filter depends on the size of soil particles. The smaller the size of particles, the higher the efficiency of removing impurity. The environment of groundwater anear the river is anaerobic as supplied by polluted river water when the concentration of NH4+ is very stable, SO42- reduces, and HCO3- increases. Then it transforms into the aerobic environment, with the result that the concentration of NH4+ reduces, NO3- and NO2- increases , HCO3- reduces, and SO42- increases abruptly, i.e. sulfuration and nitrification appears. The anaerobic environment exits in the shape of belt along the river. The width of the ribbon is affected by the slope of hydraulic-power, the size of particles, the concentration of waste water and time.
