The research on present situation and formulation of water pollutant discharge standards of river basins in China

In this paper, the water pollutant discharge standards of river basins in China are comprehensively combed, and the development and present situation of watershed water pollutant discharge standards are introduced. Based on the above, the composition and the controlled pollutants of watershed water pollutant emission standard system and the methods of setting discharge limits of pollutants are summarized. Finally, focused on the problem of the definition of watershed discharge standard, controlled pollutants and the means of determining the discharge limits, the paper puts forward some suggestions for formulating and revising the watershed water pollutant discharge standard system.
