The Design And Evaluation Of A City's Municipal Wastewater Treatment Plant Phase Second Project

As a non-renewable resources,the shortage of water resources has become more and more resources,and this phenomenon to grow.In order to human survival,for the sake of future generations,scientific development and utility of water resources has become a global problem to be solved.In the use of water a day is very high,the same sewage is also very much,if direct drainage of not only wastes a large amount of water resources,but also can cause the destruction of the environment.Compared with seawater,and rain water,sewage source easier to collect,stability,processing convenience.To reduce intense light water resources,the world has a lot of countries have issued laws and regulations for sewage,also put forward a lot of treatment of sewage and wastewater reuse scheme,effectively reduce the water pressure of the city.Sewage treatment engineering is related to the interests of individual citizens,is a public welfare undertakings.This project is the need of the development of A market economy,is to meet the needs of the development of A city water planning.After the completion of the project will change A city,the superior geographical advantages,and perfect the function of water use,alleviate the pressure of regional water.Taking A municipal wastewater treatment plant phase ii project design and evaluation as the research object,combined with what they have learned during the period of my graduate school of economic analysis method and the actual work experience,in the full investigation and analysis of the project,on the basis of the engineering construction,key technical problems and the necessity of economic rationality was analyzed.In structure,the paper is divided into six parts: part one: the introduction part.The paper mainly introduced the research background and significance,and on this basis summarizes the main content of the research in this paper.The second part: summary of related theory.The third part: the background of this project construction and market analysis.Mainly introduces the general situation of the project,analysis of the necessity of the project construction,and analyzes the main function of the project.The fourth part: the key technical analysis.On the basis of field investigation data,analyzes the key technology of the engineering problems,such as campus planning,technology solutions,water supply and drainage system equipment,environmental protection,etc.The fifth part: the project evaluation.According to the analysis of the main indicators of national economy,analyzes the economic benefits of the project,the evaluation of the project economic social evaluation and risk assessment.The final conclusion.The main conclusion summarizes this article research institute.
