Description

technical field

[0001] The invention belongs to the technical field of water treatment, and in particular relates to a sediment passivation system for black and odorous water bodies. Background technique

[0002] In recent years, with the rapid development of my country's urbanization and industrialization process, some urban water bodies, especially small and medium-sized urban water bodies, have directly become industrial, agricultural and domestic sewage due to the lag of water pollution control and treatment measures, or limited capacity or low level. The main discharge channels and places of the city lead to large-scale pollution of urban water bodies, causing eutrophication of water bodies, and eventually forming black and odorous water bodies, which have serious adverse effects on urban ecological and cultural landscapes, and have attracted more and more attention.

[0003] Currently, the treatment and restoration technologies for black and odorous water bodies mainly ...
