- Abstract:
- Affected by long-term sewage and wastewater discharge, garbage dumping and sediment movement, the river channel deposition and sediment pollution problem became severe in Maozhou River basin. Through a comprehensive investigation, the sediment pollution degree was systematically evaluated. The dredging volume was calculated by each partition through analyzing absorption-desorption characteristics in the “source-influx” experiment, the influence on flood control and bank structure was also evaluated. The dredging project was conducted mainly by a cutter suction dredger, and supplemented by small dredging equipment. It adopted the sludge-sand separation, solid-liquid separation, and plate-frame pressure filtration process to treat the dredged sediment, and the output was recycled according to the classification standards.
