由于水源水质的日益恶化以及新水质标准对供水企业常规水处理工艺改造的必然要求,提出以常规处理工艺为基础,增加预处理、深度处理或对常规处理工艺进行强化,以满足出水水质的要求。针对目前饮用水处理工艺流程甑选过程中存在的若干问题,以模糊数学多层次综合评价模型为骨架并运用层次分析法确定权重分配集合,建立给水处理工艺综合评价优选模型。通过模型对工艺流程进行评判,从而选定最优方案。通过工程算例,介绍该模型的计算流程以及评价方法。
Due to the deteriorating water quality and the inevitable requirement of the new water quality standard for conventional water treatment, it is proposed to increase the pretreatment, depth treatment or strengthen the conventional treatment based on the conventional treatment to meet the requirement of effluent quality . Aiming at some problems existing in current process of drinking water treatment process selection, fuzzy mathematics multi-level comprehensive evaluation model is used as skeleton, and AHP is used to determine the weight distribution set, and the optimal model of comprehensive evaluation of water supply process is established. Through the model to judge the process, so as to select the optimal solution. Through the engineering example, the calculation flow of the model and the evaluation method are introduced.
