City of Plantation's Indirect Potable Reuse Pilot Project: Approaches to Meeting Extreme Nutrient Limits 种植园城市的间接饮用水再利用试点项目:满足极端营养限制的方法
发布日期: 2009-11-01
本powerpoint演示文稿展示了佛罗里达州种植园市的一个项目,以确定替代水源。间接饮用水再利用- 选择了含水层补给。在选择通过地表水排放进行地下水补给时,考虑的问题包括:养分控制;MBR方案数据;常规处理方案数据;微量成分;此外,水生生物会影响毒性。演示摘要表明:该飞行员证明符合严格的营养要求 不同试验条件下的限值; 反渗透膜对地表水是必要的 由于严格的TP限制而排放; 几乎所有的微量成分都被清除了 反渗透系统; 反渗透渗透可能是有毒的再稳定/再矿化 是必要的;和 观察到的对水生生物的毒性很可能 由氯胺引起。其他形式的反渗透预处理 应该进行评估。包括数字。
This powerpoint presentation presents a project by the City of Plantation, Florida, to identify an alternative water source. Indirect Potable Reuse - Aquifer Recharge was chosen. Issues for consideration in the selection of groundwater recharge through surface water discharge with the Plantation pilot included: nutrient control; MBR scheme data; conventional treatment scheme data; microconstituents; and, aquatic organism impact toxicity. Presentation summary indicates: the pilot demonstrated to meet stringent nutrient limits at different test conditions; RO membranes are necessary for surface water discharge due to stringent TP limits; almost all microconstituents were removed by RO system; RO permeate could be toxic re-stabilization/remineralization is necessary; and, the observed toxicity to aquatic organisms was likely caused by chloramines. Other forms of RO pretreatment should be evaluated. Includes figures.
