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.

Highly effective in situ treatment method for endogenous pollution in sludge

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