【摘要】：金桥公司污水处理场项目是金桥公司500万吨/年扩能改造项目的主体工程之一。污水处理场是全公司污水处理的最后单元,工艺成熟,技术可靠。该项目在投资巨大,时间紧迫,任务繁重的情况下,只用了一年零四个月的有效工期就完成了项目建设任务,并实现了一次投产成功。随着国家对环境保护的要求日益提高,污水处理场能否平稳运行,实现污水达标排放,环保指标完全受控,成为公司发展的一个关键因素,所以有必要对污水处理场的运行进行研究。本文针对金桥公司污水处理场项目的运行特点,对项目运行进行了跟踪研究,主要有以下四个方面的内容： (1)金桥公司污水处理场项目介绍； (2)对污水处理场根据项目管理的理论进行分析和评价； (3)对污水处理场运行进行分析和研究； (4)对项目运行中出现的各种环保风险逐项提出控制措施,并进行风险防范。本文的主要特点。1、运用前后对比法,将运行二年来实际数据与可研的预期目标进行定量对比分析,结合项目实施后产生的经济效果,社会效益,经济效果包括降低水耗、减少污染物排放费用、水资源的再利用等,社会效益包括减少对周围环境的污染、节约资源、降低劳动强度、改善周边环境等来进行对比,找出偏离目标的原因及解决问题的对策。2、现场观察研究法,本论文所收集的信息和数据除了查询可研、项目立项、施工准备、开工建设等相关的文件之外,最主要的来源是本人根据投产后运行及日常技术管理工作所获的第一手资料,经过整理后得出的,所有数据都是生产运行的真实记录,对管理技术人员分析解决实际问题具有很强的指导意义。3、层次分析法,主要采用定性和定量相结合的分析方法,根据要求的目标和问题的性质,将项目分解为不同层次的各要素,按照各要素之间的层次和关系,从项目运行模式、工艺路线选择、设备选型方面、资源能源利用、污染物的产生、过程控制、工艺技术、管理、员工、产品、废弃物等方面,分别去发现该项目运行过程当中存在的主要问题,并归纳产生这些问题的主要原因,分层次的提出具体解决方案,从而为以后污水处理场项目的开展提供参考和实践依据。4、通过对项目施工初期、生产运行等活动过程中对周边环境的影响作为评价的关键要素,纳入到工程项目管理和日常运行中,将环境保护责任落实到岗位、到员工；通过实施环境管理体系,为各管理层次、作业现场和承包商提供可靠的作业程序和标准。
[Abstract]:The sewage treatment site project of Jinqiao Company is one of the main projects of 5 million t / a capacity expansion project of Jinqiao Company. Sewage treatment plant is the last unit of the whole company sewage treatment, the technology is mature, the technology is reliable. In the case of huge investment, tight time and heavy tasks, the project has completed the project construction task with only one year and four months effective construction period, and has realized the success of putting into operation once. With the increasing demand of the state for environmental protection, whether the sewage treatment plant can run smoothly, achieve the discharge standard of sewage, and completely control the environmental protection target, has become a key factor in the development of the company. So it is necessary to study the operation of sewage treatment plant. According to the operation characteristics of the sewage treatment plant project of Jinqiao Company, the project operation is tracked and studied in this paper. The main contents are as follows: 1) introduction of sewage treatment site project of Jinqiao Company; 2) Analysis and evaluation of sewage treatment plant according to the theory of project management; 3) analysis and study of sewage treatment plant operation; 4) To put forward the control measures one by one for all kinds of environmental protection risks that appear in the operation of the project, And risk prevention. The main features of this paper are as follows: 1. By using the method of comparison before and after operation, the actual data of two years of operation are compared with the expected objectives of research. The economic effect, social benefit and economic effect, including reducing water consumption, are combined with the economic effect after the implementation of the project. Social benefits include reducing pollution to the surrounding environment, saving resources, reducing labor intensity, improving the surrounding environment, and so on. Find out the cause of deviation from the target and the countermeasures to solve the problem. 2. The field observation and research method. The information and data collected in this paper are in addition to the relevant documents, such as inquiry and research, project establishment, construction preparation, start construction and so on. The most important source is the first-hand information obtained by me from the operation after production and the daily technical management work. After collation, all the data are true records of production and operation. It is of great guiding significance for management technicians to analyze and solve practical problems. The Analytic hierarchy process (AHP) mainly adopts qualitative and quantitative analysis methods, according to the required objectives and the nature of the problem, The project is decomposed into different levels of elements, according to the levels and relationships between the elements, from the project operation mode, process route selection, equipment selection, resource and energy use, pollutant generation, process control, process technology, Management, staff, products, waste, etc., to find out the main problems existing in the running process of the project, and to sum up the main causes of these problems, and put forward concrete solutions to these problems at different levels. So as to provide reference and practical basis for the future development of sewage treatment plant projects, through the initial construction of the project, production and operation of activities such as the impact on the surrounding environment as a key element of the evaluation, Incorporate into the project management and daily operation, implement the environmental protection responsibility to the position, to the staff; through the implementation of the environmental management system, provide reliable operating procedures and standards for all levels of management, operation site and contractor.
