技术经济评价的方法很多,一般可分为所得法和所费法。如果再考虑时间因素,上述每一种方法中又可用静态分析和动态分析法来计算。目前化学水水站的技术经济比较一般常用所得法中的偿还年限法来进行,对小型化学水水站,为简化计算,在计算偿还年限法时用静态分析法来进行计算。
There are many methods of technical economic evaluation, which can be generally divided into income method and fee method. If you consider the time factor again, static analysis and dynamic analysis can be used for each of the above methods. At present, the technical and economical water and chemical stations are compared with the repayment time method used in the commonly used method of obtaining income. For small chemical water and water stations, in order to simplify the calculation, the static analysis method is used to calculate the time of repayment calculation method.
