Computerized Comparision And Selection Of Municipal Wastewater Treatment Techniques

Our country is one of water resources relatively leanness. Due to the speed up of urbanization process and high-speed development of national economy recently, Water pollution in our country has been seriously. Recovery water environment is the basic method to solving water resources deficiency. Experience in domestic and overseas indicate that constructing waste water treatment plants is an effective way. Comparison and selection of process scheme is one of most important stages in the construct of municipal wastewater treatment plants.This paper studied the feasibility of using computer software to achieve urban sewage treatment process selection. Establish a practical calculation of the sewage treatment process and system selection. The engineering staff of the calculation of the sewage treatment process and the election process using computer. So calculated avoid the artificial complex then enhance the efficiency and objectivity recommended by the authenticity of the program.Firstly, In this paper, a large number of collected data based on the sewage treatment process and the election process, analysis many impact of factors, Urban sewage treatment in the basic principles of process selection, together with the contents of this paper,established a comprehensive urban sewage treatment process selection index system.Secondly, in order to "Code for design of outdoor wasterwater engineering" as a guide, Integrated a large number of sewage treatment plants Design Manual and information, Structure of the sewage treatment plant tank in particular to the calculation procedure of the realization, that is, man-machine dialogue through the user input parameters, to achieve results fast.Thirdly, the use of comprehensive evaluation of the ideas, The establishment of a multi-level fuzzy gray coupled model, used of Analytical Hierarchy Process (AHP), science at all levels to calculate the weight of the indicators, Re-use of gray system theory of gray relational grade analysis of alternative engineering solutions to the various indicators of the specific results of analysis, comparison and selection in order to ultimately achieve.Finally, used of the mainstream of the WEB application development languages-JAVA and visual authoring software Dreamweaver as a tool, And used of general open-ended design, through the formation of man-machine dialogue automatic evaluation system, the computer in the background, the direct result will be displayed, Sewage treatment process so as to provide a preferred means of advanced, improved work efficiency.
