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.

Abstract: A risk prediction and early warning method for water environments based on a water environment model predicting pollution discharge information for all pollution sources in a watershed, and including: selecting pollution sources requiring environmental risk prediction and early warning and dividing these into different risk prediction/early warning levels; determining from official environmental monitoring data and literature research initial elements for environmental pollution risk evaluation; obtaining principal pollution elements affecting pollution events; generating a plurality of environmental risk prediction and early warning models; forming a comprehensive fuzzy risk prediction and early warning model by combining the several risk prediction and early warning models having the best selective performance; inputting principal pollution element values into the comprehensive fuzzy risk prediction and early warning model, and predicting risk values for pollution events at pollution sources.
