摘　　要：以黄河水为水源的济南市供水系统为研究对象,选取生物可降解溶解性有机碳(BDOC)作为评价生物稳定性指标,分析地表水厂和管网的水质生物稳定性变化。结果表明:水厂常规净水工艺处理后BDOC去除率为10%～32%,出厂水BDOC在0.1～0.2 mg/L之间,低于0.2 mg/L生物稳定性水中BDOC的建议限值。出厂水水质直接影响管网水质,随着管网延伸BDOC相对稳定;BDOC与浊度、总有机碳(TOC)等指标呈正相关。水厂采用臭氧活性炭深度过滤工艺改造后,BDOC值进一步降低,生物稳定性提高。With the water supply system of the Yellow River source water in Jinan as the study target, and biodegradable dissolved organic carbon （BDOC） as the indicator to evaluate the biological stability, water biological stability variation of the surface water and the pipe network are analyzed. The results show： BDOC removal efficiency of 10% to 32% after the processing of the waterworks conventional water purification process, the BDOC value of the finished water is between 0.1 mg / L and 0.2 mg / L, less than 0.2 mg / L biological stability of water recommended value. The factory water quality direcly impacts on the water quality of the pipe network, and with the extension of the pipe network, BDOC value is relatively stable. BDOC is positively correlated with turbidity, total organic carbon （TOC） and other indicators. After the ozone activated carbon depth filter technology transformation, the BDOC value further reduces, and the water biological stability improves.
