Research on Manganese Contamination and Genesis in Jilihe Reservoir

Based on manganese content surpass the set standard seasonally in Jilihe reservoir´s water, manganese content in the catchment basin of the river water, river sediment and the surrounding soil were analyzed, the environmental geochemical factors which impact manganese content were studied. According to the survey results, the reservoir water quality has obvious stratification: Dissolution of manganese in low-layer area impact water concentration greatly, and rainfall in summer can turn sediment over to promote the release of manganese, which is the main reason for manganese content exceeded the standard. Manganese pollution prevention and control measures were proposed based on research results.
