基于MATLAB的污水管道工程管径比选

Comparison and selection of pipe diameter in sewage pipelineproject based on MATLAB

为优化投资与运行效益,采用费用现值法和MATLAB软件进行数学运算,对新建泵站排水管道工程管径进行比选。结果表明:在泵站水量为30000、45000、60000 m^3/d等条件下运行30年,DN 800管道都具有较好的经济性,可以有效应对由污水量不确定性导致的工程投资效益问题。

In order to optimize the investment and operating benefits,the cost present value method and MATLAB software were used for mathematical calculations to compare and select the pipe diameters for a drainage pipeline project in a new pumping station.The results showed that if the pumping station operated for 30 years with water flow rates of 30000,45000,and 60000 m^3/d,pipeline with nominal diameter of 800 mm was more economical and can effectively deal with the project investment benefit problem caused by the uncertainty of sewage flow rate.
