Blending Desalinated Seawater with Treated Surface Water: Impact on Chlorine Dose and THM Formation 将脱盐海水与处理过的地表水混合:对氯剂量和THM形成的影响
发布日期: 2009-11-01
本powerpoint演示文稿首先简要概述阿德莱德(澳大利亚)海水淡化厂。项目目标是调查混合脱盐水的效果 与跑马地水处理厂(WTP)的产品水不同 混合比例对水质的影响包括:氯的衰减;消毒副产物形成; 味道和气味;以及生物稳定性。预期的结果是: 提供信息以确定产品规格 海水淡化水质;和 确定脱盐和盐的混合比范围 可利用的欢乐谷WTP产品 不会对水质造成不利影响。跑马地水处理厂产品水: 常规处理——明矾凝聚、絮凝、, 沉淀和过滤; 应用于沉淀水中的氯(达到0.3 mg/L 过滤后); 氯化前、最终过滤后取样;和 使用前将样品储存在4ºC下。介绍了氯衰变和模拟分配系统(SDS)试验的消毒策略,以及氯衰变、三卤甲烷生成、高DOC/溴化物水和低DOC/溴化物水的结论。包括表格、数字。
This powerpoint presentation begins by providing a brief overview of the Adelaide (Australia) Desalination Plant. Project objective was to investigate the effects of blending desalinated water with Happy Valley Water Treatment Plant (WTP) product water at different blend ratios on water quality including: chlorine decay; disinfection byproduct formation; taste and odor; and, biological stability. Desired outcomes were to: provide information to determine specification for desalinated water quality; and, determine a range of blend ratios for desalinated and Happy Valley WTP product that can be utilized without a detrimental impact on water quality. Happy Valley WTP product water: conventional treatment - alum coagulation, flocculation, sedimentation and filtration; chlorine applied to settled water (achieve 0.3 mg/L after filtration); samples taken after filtration, prior to final chlorination; and, samples stored at 4 ºC before use. Disinfection strategy is presented for chlorine decay and simulated distribution system (SDS) test, along with conclusions for chlorine decay, trihalomethane formation, high DOC/bromide water, and low DOC/bromide water. Includes tables, figures.
