Abstract:
The invention discloses a method for harmless treatment of cyanophytes and suspended solids accumulated in lakeside wetlands, comprising the following steps: first, adding a flocculant to a water body to be treated, so as to allow the flocculation of cyanophytes to accumulate in the surface layer of the water body, and settling the formed cyanophycean floc to the surface layer of sediments; second, adding a floc stabilizer to perform accumulation and compaction of the cyanophycean floc and stabilized treatment of the floc in the surface layer; finally, conducting further reoxygenation treatment on the bottom water body. The method of the invention can realize efficient and ecologically safe flocculation of accumulated cyanophytes at low cost and control odor compounds such as sulfides decomposed from flocculated cyanophytes, so as to provide a new method for harmless treatment of excess cyanophycean accumulation in eutrophic lakes.

Claim (Index 11):
The method according to  claim 9 , characterized in that the carbon is selected from the biological carbon consisting of difficult-to-be-decomposed stems and leaves of the wetland plants and easy-to-be-decomposed stems and leaves thereof; the difficult-to-be-decomposed stems and leaves of the wetland plants are selected from one or more of reeds, cattails and straw stalks; the easy-to-be-decomposed stems and leaves thereof are selected from one or more of bitter herbs,  Potamogeton malaianus  and  Nymphoides peltatum (Gmel.) O. Kuntze; the mixing mass ratio of the difficult-to-be-decomposed stems and leaves of the wetland plants to the easy-to-be-decomposed stems and leaves thereof is 2-5:0.2-1.5, and the adding mode is of low intensity and high frequency.
