The invention discloses a sediment improver for black and odorous water, which is composed of the following raw material components in percentages by weight: 20-40% of potassium ferrate, 25-35% of quicklime, 5-10% of polyaluminium chloride, 5-15% of potassium persulfate, and 15-25% of zeolite. Through the sediment improver for the black and odorous water provided by the invention, organic matterscan be completely decomposed, eutrophic substances are adsorbed and fixed, the sediment environment is completely changed, so the reproduction and growth of microorganisms and aquatic animals in waterare promoted, thereby accelerating the restoration of ecosystems.

The invention discloses a novel artificial ecological riverbed and a construction method. The novel artificial ecological riverbed comprises a composite fiber ecological mat with the thickness of 50mm, an aquatic plant body, a riverbed body and mud nails. Compared with the prior art, the novel artificial ecological riverbed is good in environmental protection performance, low in implementation cost, convenient to construct and capable of being widely applied to some eutrophicated, black and odorous water areas and urban landscape water areas needing water quality improvement, aquatic plants bred in the composite fiber ecological mat gradually grow as time goes on in the later period, the effects of beautifying the environment, purifying the water quality, improving the climate and effectively controlling water and soil loss can be achieved, and meanwhile, the diversity of species can be maintained; the plane shape of the novel artificial ecological riverbed can be arranged in a diversity mode, and a graceful landscape environment can be created according to the forms of the aquatic plants and diversified combination modes, so that a leisure and entertainment space is provided for people.
