【摘要】：唐山市是我国水资源短缺严重的城市之一。目前唐山在城市污水处理工作方面还没有形成统一的标准,对污水处理工艺的选择还缺少评判方法。随着我国污水处理技术水平的不断发展,在污水处理上的方案越来越成熟,可供选择的范围也越来越大,选择一个恰当的污水处理工艺方案对污水处理上的投入、处理效率、运营能力等起着至关重要的作用。文章以唐山市污水处理工艺为研究对象,通过文献资料搜集等途径首先分析了唐山市的水资源概况及污水处理的现状;然后,在通过实地调研等手段对目前唐山市部分污水处理厂进行现有工艺方案进行调研的基础上,进行了全面技术分析和经济分析,在本文中引入了新的分析问题方法即层次分析法,并建立了有关污水处理工艺方案选择的优化模型。当前的污水处理采用的方案是以分析数据为主,但新建立的模型的评价结果却更为客观全面,因此其为控制污染源提供了强有力的依据。优化模型的优化结果显示:该模型如果应用在唐山市的污水处理工艺方案的选择方面,权重最大的要数投资费用和处理费用,出水的稳定性和操作管理的权重仅次于前者,权重最小的是占地面积和除磷脱氮的效果。所以,污水处理的最优的方案是缺氧/好氧法,氧化沟法为次选方案。
[Abstract]:Tangshan City is one of the cities with serious shortage of water resources. At present, Tangshan has not formed a unified standard in the field of municipal sewage treatment, and the selection of sewage treatment technology is still lack of judgment method. With the continuous development of sewage treatment technology in our country, the scheme of sewage treatment is more and more mature, and the scope of choice is increasing. Operational capacity and so on plays a vital role. This paper takes the wastewater treatment technology of Tangshan City as the research object, analyzes the general situation of water resources and the present situation of sewage treatment in Tangshan City by means of literature and data collection, and then analyzes the current situation of wastewater treatment in Tangshan City. Based on the investigation of the existing process schemes of some wastewater treatment plants in Tangshan City, the comprehensive technical analysis and economic analysis are carried out. A new analytical method, the Analytic hierarchy process (AHP), is introduced in this paper. An optimized model for the selection of wastewater treatment process was established. The current scheme of sewage treatment is based on the analysis of data, but the evaluation results of the new model are more objective and comprehensive, so it provides a strong basis for the control of pollution sources. The optimization results show that if the model is applied to the selection of wastewater treatment process in Tangshan City, the most important factors are investment cost and treatment cost, and the stability of effluent and the weight of operation management are second only to the former. The smallest weight is the area occupied and the effect of phosphorus and nitrogen removal. Therefore, the optimal scheme for wastewater treatment is anoxic / aerobic process and oxidation ditch method is secondary selection scheme.
