AI Technical Summary
Existing technologies for intercepting non-point source pollution in riparian zones suffer from low interception efficiency, low material utilization rate, and the risk of secondary pollution, as well as low utilization rate of sludge resources in water supply.
Using a low-organic-matter sludge modification material processing device, a modified material with high-efficiency adsorption performance is prepared through screening, tapping and composite modification treatment. Attapulgite, hydroxyapatite and ferric chloride are used as the skeleton filling phase and binder phase of the flocs to form a three-dimensional network composite floc structure.
It achieves the ability to efficiently intercept dissolved nitrogen and phosphorus, reduces sludge disposal costs, avoids secondary pollution, improves resource utilization, reduces the risk of heavy metal leaching, and improves the service life and ecological compatibility of materials.
