Computerized Quantitative Method Comparision And Selection Of Municipal Wastewater Treatment Techniques And Application

In the "12th five-years" period, construction projects will continue to be promoted, which contains new sewage treatment plants construction and existing wastewater treatment plant upgrading, and reclaimed water use. More attention will be paid on sewage treatment facilities construction in prefectures and town, the goal that each prefecture owns sewage treatment plants can come true. In the next ten years, every year, there will be a large number of wastewater treatment plants constructed and put into use. Sewage treatment process scheme selection is a major part of the sewage treatment plant construction. Therefore, study on comprehensive evaluation of water treatment plants should be carried out with large theoretical significance and important study value.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.In this paper, presented an integrated quantified method for urban sewage treatment process selection, comprehensive quantitative indicators include total investment, operating costs, total energy consumption and total land footprint. According to the drainage design standard (outdoor GB50014-2006), study calculation method of structures, particularly the biochemical reaction tank in sewage treatment plant (such as A2O, oxidation ditch and modified SBR), and implement calculation procedures using the C++programming language of wastewater treatment plant technology, with which users input parameters and then the calculations results should be quickly concluded. In terms of calculating algorithms and logic implementation, C++is a type of static data check programming language, which supports multiple programming paradigms universal programming language. In respects of interface design and production, C++should guarantee the style and appearance of page.This article, taking Xi'an sewage treatment plant IV for instance, verified the whole implementation process of comparison and selection, which makes the comparison and selection system more scientific and more accurate. In order to improve the operability of the software system, a detailed instruction of the system was given.Our research results provide advanced means of the municipal wastewater treatment process optimization, giving the full advantage to the computer systems which can handle large amount of data with quick and accurate calculations. This system is highly practical, which improved the efficiency, increased the objective authenticity of comparison and selection process.
