摘要

The causes of formation of black and smelly river water were summarized,including the entry of organic pollutants into rivers,such as domestic waste,three industrial wastes,thermal pollution caused by industrial hot drainage,pollution of the river bottom and resuspension movement,and so on. The existing modes and valence changes of iron,sulfur and other elements in black and smelly water were discussed. It is clear that the formation of the black and stink is mainly caused by blackening factors and stink-causing factors. It is concluded that the main blackening factors are ferrous sulfide,manganese sulphide,and the main stink-causing factors are hydrogen sulfide,ammonia or sulfides( VOSCs),josamidine and 2-dimethyl isobenol based on sulfur elements. It provides theoretical reference for the control of black and smelly river water in island cities.
