摘要
在调研武汉市排水管道日常疏浚污泥量的基础上,运用鲁棒优化理论建立模型,预测2025年武汉市日常疏浚污泥量将达到437036 m^(3)。根据鲁棒优化模型运行结果研究疏浚频次对疏浚污泥量的影响,得到较优疏浚频次为4次/年。分流制排水管道的疏浚污泥量明显少于合流制管道;不同用地功能对疏浚污泥量的影响程度为:商业区>文教区>居民区>综合服务区;此外,PVC管材的疏浚污泥量明显低于钢筋混凝土管,疏浚污泥量与管道管径呈正相关。
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 437036 m^(3)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.
