| 摘要: |
| 为使污泥输送管道的建设与运行经济合理,降低其建设与运行的总费用,构建了污泥输送管道的年折算总费用模型,分析了模型中污泥质量分数ww和输送速度v对年折算总费用W的影响,并将此二设计参数选定为待优化变量．鉴于该模型的复杂非线性,利用GA-DE组合算法的全局并行寻优能力对上述模型进行求解. 结果表明,该组合算法对于优化污泥输送管道的设计参数是有效的．以长春市某污水处理厂污泥输送工程为例,分析了污泥流量Q=0.226～0.045 m3／s(污泥质量分数ww=0.8％～4.0％),输送距离L=4.5×103 m条件下的最优设计参数为:污泥质量分数ww=2.32％,输送流速v=1.10 m／s,管径D=300 mm,年折算总费用W=52.83万元． |

| Abstract: |
| To insure the construction and running of slurries transportation pipeline be economical, the annualized conversion total cost model of slurries transportation pipeline was set up. Considering the impact of slurries concentration and slurries convey velocity on total cost of slurries transportation pipeline, these two parameters were chosen to be variables for optimizing. In view of the complex nonlinear of the model, the parallel global search ability of combined GA-DE (genetic algorithm-differential evolution) algorithm was utilized to optimize the design parameters of slurries transportation pipeline, the result of which was proved effective. Then this method was applied to a sludge treatment plant for final disposal in Changchun City. The optimization results showed that the optimum slurries concentration was 2.32％, the transportation velocity was 1.10 m／s, the diameter of the pipeline was 300 mm, and the annualized conversion total cost was 528.3 thousand Yuan RMB under the condition of flow rate of 0.226-0.045 m3／s (slurries concentration varying from 0.8％ to 4.0％) and the transportation distance of 4.5 kilometers. |
