This paper describes an innovative systematic approach, namely hierarchy grey relational analysis for optimal selection of wastewater treatment alternatives, based on the application of analytic hierarchy process (AHP) and grey relational analysis (GRA). It can be applied for complicated multicriteria decision-making to obtain scientific and reasonable results. The effectiveness of this approach was verified through a real case study. Four wastewater treatment alternatives (A(2)/O, triple oxidation ditch, anaerobic single oxidation ditch and SBR) were evaluated and compared against multiple economic, technical and administrative performance criteria, including capital cost, operation and maintenance (O and M) cost, land area, removal of nitrogenous and phosphorous pollutants, sludge disposal effect, stability of plant operation, maturity of technology and professional skills required for O and M. The result illustrated that the anaerobic single oxidation ditch was the optimal scheme and would obtain the maximum general benefits for the wastewater treatment plant to be constructed.
本文介绍了一种创新的系统方法，即基于层次分析法（AHP）和灰色关联分析（GRA）应用的层次灰色关联分析法，用于废水处理方案的优化选择。它可应用于复杂的多准则决策，以获得科学合理的结果。通过实际案例研究验证了该方法的有效性。对四种废水处理方案（A(2)/O、三槽氧化沟、厌氧单槽氧化沟和SBR）进行了评估，并根据多个经济、技术和管理性能标准进行了比较，包括资本成本、运营和维护（O&M）成本、占地面积、氮磷污染物去除率、污泥处置效果、工厂运营稳定性、技术成熟度以及O&M所需的专业技能。结果表明，厌氧单槽氧化沟是最优方案，将为拟建的污水处理厂带来最大的综合效益。
