摘　　要：饮用水是人类赖以生存的重要资源,尽管饮用水水质一直受到最为严格的监测,但在供水管网末端水龙头处仍会出现出水微生物学指标超标问题,由此引发的水媒传染病依然对全世界构成严重的健康威胁。因此提高供水管网水质生物稳定性对于保障管网末端水质安全意义非凡。介绍了供水管网中各项条件对水质生物稳定性的影响;简述国内外用于评价管网水质生物稳定性的各项指标,并着重论述生物可降解溶解性有机碳(BDOC)测定方法的演变及其相关模型的研究现状;总结了维持供水管网生物稳定性的注意事项和措施并展望了该领域未来的研究发展趋势。Drinking water is an important resource for human survival.Although the quality of drinking water has been subject to the most stringent monitoring,the microbiological indicators of the effluent still exceed the standard at the tap at the end of the water supply network,and the resulting water-borne infectious diseases still pose a serious health threat to the world.Therefore,improving the biological stability of water supply network is of great significance to ensure the safety of water quality at the end of the network.Firstly,the influence of various conditions in the water supply network on the biological stability of water quality is introduced in detail.Then,the indicators used to evaluate the biological stability of water quality in pipeline networks at home and abroad are briefly described,and the evolution of biodegradable dissolved organic carbon(BDOC)determination methods and the research status of related models are emphatically discussed.Finally,the precautions and measures to maintain the biological stability of water supply network are summarized from three aspects.
