  • Patent number: 11339074
    Abstract: The present invention discloses a highly effective in situ treatment method for endogenous pollution in sludge, belonging to the field of environmental engineering water treatment. In view of the problem that it is difficult to effectively treat the endogenous pollution of river sludge, the present invention provides the highly effective in situ treatment method for endogenous pollution in sludge, which specifically adopts a combination of phoslock, calcium peroxide and aluminum modified zeolite to perform in-situ remediation of sludge, effectively inhibit the release of endogenous pollution of sludge, facilitate the ecological treatment of polluted water subsequently, and finally realize the long-term water improvement against pollution.
    Type: Grant
    Filed: April 27, 2018
    Date of Patent: May 24, 2022
    Assignee: Nanjing institute of Environmental Sciences, Ministry of Ecology and Environment
    Inventors: Yimin Zhang, Ming Kong, Longmian Wang, Ruihua Meng, Yuexiang Gao, Jianying Chao, Fei Yang, Fuquan Peng, Yueming Zhu

  • Patent number: 9580342
    Abstract: The present disclosure relates to methods for cooperative control of microcystis aeruginosa by using chub, bighead, catfish and daphnia, and belongs to the technical field of water treatment. The microcystis aeruginosa in a water body is controlled using a food chain relationship; the chub, the bighead, the catfish and the daphnia can directly eat the microcystis aeruginosa in a filtering manner; and meanwhile, the chub, the bighead and the catfish also can intake the daphnia, so as to indirectly consume the microcystis aeruginosa in the water body, wherein the fishes, the daphnia and the microcystis aeruginosa form the food chain relationship; in addition, the microcystis aeruginosa at the upper, middle and lower layers and a microcystis aeruginosa hypopus at the bottom layer can be controlled by fully utilizing the vertical spatial distribution difference of the three fishes in the water body.
