NOVELTY - Ecological restoring of black-smelly river comprises removing sewage outlet of river two banks; intercepting the sewage flowing into the river; setting multiple dam to partition along the river water flow direction; multiple partition river water into biological enzyme preparation particles for biological decomposition, biological decomposition for 12-15 days, adding flocculating agent into the water, allowing to stand for 20-30 days and removing the river channel; adding deodorizer into the river water, at the same time, adding graphene photo-catalytic net on the surface of the central water body, removing black and smelly water body; adding deodorizer for 12-20 days, adding microbial sewage treatment agent into water, degrading the organic matter in the water, and adding microbial sewage treatment agent; planting submerged plant in water body, and placing fish, shellfish and shrimp animal, planting emergent aquatic plant on the ecological floating bed; and manual inspecting. USE - The method is useful for ecological restoration of black and smelly river. ADVANTAGE - The method has strong operability, thorough treatment and high treatment efficiency, gradually recovering self-cleaning ability of water, gradually removing peculiar smell and chroma of black and smelly water, finally realizing ecological balance of water body, improving water quality, making water ecological system can develop long-term healthy and stable, and has good environment-friendly and ecological function.
