| With the development of domestic economics level, the living quality wassignificantly improved. However some side-effects of economics booming alsoemerged. One of them is shortage of water resource. There have been a lot ofproblems being considered to be the reason of causing shortage of water resource. Thewater pollution caused by industrialization is among them. Currently the averageliquid treatment efficiency is far more below those of in industrialized country. So itcan be foresee that in20years, the problem of low liquid effluent treatment abilitywill draw great attentions from government and society. Cost control plays asignificant role in the process of liquid effluent treatment. Better cost control canmake the process more efficiently thus enhance the market competition of watertreatment enterprise and stimulate the production enthusiasm of enterprise.There have been a lot of methods to bring cost control namely Activity-BasedCosting, Value Analysis, Target costing and Earned Value. In present paper, themerits and drawbacks of above listed method have been compared and discussed inorder to find a optimized method for cost control of liquid effluent treatmentengineering which turned out to be Earned Value method. Then a brief introduction ofthe incipience and development of Earned Value method was presented in this paperfollowed by elaborating Earned Value method through a Bluestar environmentalengineering’s case of water treatment engineering which applies this method. In theend, a unique advantage of using Earned Value cost control method was summarized.And some suggestions of how to control cost more scientifically were forwarded. |
