Integral Optimization of Drinking Water Treatment Plants 饮用水处理厂的整体优化
发布日期: 2006-11-01
为了对饮用水处理厂的运行进行整体优化 必须为运行控制确定和定义优化目标。这篇论文 讨论水质、环境影响方面的目标 以及成本。因此,对饮用水生产厂进行了综合评估 Weesperkarspel水网公司(前身为阿姆斯特丹供水公司)。结论是: 饮用水处理厂整体优化的目标应该是水质和水质 成本。管理层应决定水质和成本之间的相对权重 请记住,荷兰饮用水公司面临的最大威胁是水的使用 饮用瓶装水,但无法保证自来水质量;或 客户不信任自来水的质量。因此,必须把重点放在保持高收入上 饮用水质量。环境影响不应成为运营管理的目标 优化饮用水处理厂,因为环境影响相对较低 并且通常会从成本优化和良好的生产实践中受益,例如 例如使用100%绿色能源。假设消毒和清除工作暂停 固体和颗粒物充足,整体优化的水质参数为SI 化学稳定性、AOC和/或可生物降解的DOC和用于生物稳定性和消毒的DOC 副产品和有机微量污染物的毒性。自从SI,AOC,DOC和病原体 浓度受许多过程的影响,并以积分的形式影响许多过程 这些参数的逼近是必要的。因为关系和影响的复杂性 通过对这些参数的变化进行操作控制,可以最好地采用不同的控制策略 通过积分模型进行评估。包括23个参考文献、表格和图表。
In order to perform an integral optimization for operation of a drinking water treatment plant, explicit objectives for optimization have to be identified and defined for operational control. This paper discusses what these objectives should be with respect to water quality, environmental impact and costs. Therefore integral assessments are performed for the drinking water production plant Weesperkarspel of Waternet (formerly Amsterdam Water Supply). It is concluded that the objectives for integral optimization of drinking water treatment plants should be water quality and costs. The management should decide upon the relative weight between water quality and costs keeping in mind that the greatest threat for drinking water companies in The Netherlands is the use of bottled water for drinking, when tap water quality cannot be guaranteed for that purpose or clients do not trust the tap water quality. Therefore, emphasis must be laid on maintaining the high drinking water quality. The environmental impact should not be an objective for operational optimization of drinking water treatment plants because the environmental impact is relatively low and will in general benefit from optimization of cost and from good manufacturing practice, for instance the use of 100% green energy. Assuming that disinfection and removal of suspended solids and particles are sufficient, the water quality parameters for integral optimization are SI for chemical stability, AOC and/or biodegradable DOC and DOC for biological stability and disinfection byproducts and organic micro-pollutants for toxicity. Since the SI, AOC, DOC and pathogen concentration are influenced by many processes and influence many processes an integral approach of these parameters is necessary. Because of the complexity of the relations and effects on these parameters by changes in the operational control, different control strategies can best be evaluated by an integral model. Includes 23 references, tables, figures.
