研究了不同水质混合对配水系统水质的影响 在这项实地研究中进行了调查。五种不同处理系统产生的水；曝气 （G1）、NF（G4）、CSF-O3-GAC（S1）、IMS（CSF-NF或S2）和高压反渗透（RO）混合 并分发到18个不同的飞行员分配系统（PDS）。G1、G4和RO水源水 都是从同一个地下水中提取的。在反渗透源中添加盐以模拟 海水。S1和S2水源取自同一地表水。PDS 由PVC、镀锌、内衬球墨铸铁管和铸铁管组成，取自现有配电系统 并进行了为期5天的HRT。添加氯胺以满足CT和残留要求。 AOC、BDOC、HPC是悬浮生物活性的量度。佩帕测量附加胶片 生物活性。 S2和G4 AOC基本相等，但RO AOC减小且小于 其他治疗。S1和S2 AOC相等。PDS的生物稳定性顺序为G1<G4=S1=S2<RO。 在雨季，未经处理的地表水TOC显著增加，S1 AOC也显著降低 增加。BDOC与HPC无相关性，BDOC敏感性不足以评估 处理间的生物稳定性。PDS硝化发生在2002年6月和7月，原因是 在25摄氏度至30摄氏度和pH值7.8至8.3条件下，残余物的损失。在硝化过程中，HPC值 显著增加，D.O.下降；硝化作用几乎完成，这提供了一个 当系统变得微需氧时，异养菌的碳源。AOC和Pepa评估 生物稳定性分析表明，HP RO提高了成品水的生物稳定性，但NF没有改善 在正常条件下，相对于高级地表水处理的生物稳定性。NF确实有所改善 雨季的生物稳定性。包括19个参考文献、表格和图表。

The effect of blending different water qualities on distribution system water quality was investigated in this field study. Waters produced from five different treatment systems; aeration (G1), NF (G4), CSF-O3-GAC (S1), IMS (CSF-NF, or S2) and high pressure reverse osmosis (RO) were blended and distributed to 18 different pilot distribution systems (PDS). G1, G4, and RO source waters were taken from the same groundwater. The RO source was augmented with salts to simulate seawater. The S1and S2 source waters were taken from the same surface water. The PDSs consist of PVC, galvanized, lined ductile iron and cast iron pipes taken from existing distribution systems and had a 5-day HRT. Chloramines were added to meet CT and residual requirements. AOC, BDOC, HPC are measures of suspended biological activity. PEPA measures attached film bioactivity. The S2 and G4 AOC are essentially equal, but the RO AOC is reduced and less than other treatments. S1 and S2 AOCs are equal. PDS biostability order is G1<G4=S1=S2<RO. During the wet season, raw surface water TOC increased significantly, and S1 AOC was also increased. BDOC was not correlated to HPCs and BDOC sensitivity was not adequate to assess biostability among treatments. PDS nitrification occurred in June and July 02 as the result of a loss of residual at 25oC to 30 oC and pH 7.8 to 8.3. During nitrification, the HPC values increased significantly, D. O. decreased; nitrification was nearly complete, which provided a carbon source for heterotrophs as the system became microaerophilic. AOC and Pepa assessment of biostability indicated HP RO increased biostability of finished water, but NF did not improve biostability relative to advanced surface water treatment at normal conditions. NF did improve biostability during the wet season. Includes 19 references, tables, figures.
