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.
