- Abstract:
- Based on the investigation of daily dredged sludge volume of drainage pipes in Wuhan, a model was established by using robust optimization theory, and it was predicted that the daily dredged sludge volume in Wuhan would reach 437 036 m3 in 2025. The effect of the dredging frequency on the accumulated volume of the dredged sludge was investigated according to the simulated results of the robust optimization model, and the optimal dredging frequency was 4 times per year. The volume of the dredged sludge in the separated drainage system was obviously smaller than that in the combined drainage system. The influence degree of different land use functions on the dredged sludge volume in descending order was commercial area, culture and educational area, residential area and integrated service area. In addition, the dredged sludge volume in the PVC pipe was obviously smaller than that in the reinforced concrete pipe, and the dredged sludge volume was positively correlated with the pipe diameter.
