    • A method of tracing sewage effluent is described in which samples of fluid flows are subjected to high performance liquid chromatography with respective elution systems capable of eluting different selected compounds therefrom, and the concentration of each compound in the sample is determined spectroscopically. The method is used to determine sewage flow paths in natural water bodies, such as rivers, to check for contamination by sewage, to determine possible sewage sources, the detection of uric acid, for example, being indicative of a human source; and to monitor the effluent from sewage treatment plants.A monitoring system for sewage treatment works is also described in which bromophenol blue is added to the sewage influent to the biodegradation stage as a dilution indicator and the changes in the bromophenol blue concentration and in the concentration of a biodegradable sewage component, such as uric acid, are monitored throughout the stage to give an indication of the progress of the biodegradation reaction; this information is used in controlling the operation of the plant to maximize its efficiency.
    • 描述了一种追踪污水流出物的方法,其中流体流动样品经受高效液相色谱法,其中各洗脱系统能够从其中洗脱不同的选定化合物,并且通过光谱法测定样品中各化合物的浓度。 该方法用于确定天然水体如河流中的污水流动路径,以检查污水污染,确定可能的污水源,检测尿酸,例如指示人源; 并监测污水处理厂的废水。 还描述了用于污水处理工程的监测系统,其中将溴酚蓝作为稀释指示剂加入到生物降解阶段的污水中,并且溴酚蓝浓度和可生物降解的污水组分(例如尿酸)的浓度 在整个阶段进行监测,以指示生物降解反应的进展; 该信息用于控制工厂的运行以最大化其效率。
