给水管网中生物稳定性控制指标的研究

Study on Indicators of Controlling Biological Stability in Water Distribution System

本文主要研究了给水管网生物稳定性的问题,分析了饮用水中评价生物稳定性的四项指标:可生物同化有机碳(AOC)、可生物降解溶解性有机碳(BDOC)、可生物利用磷(MAP)和总磷(TP),以及各指标的测定方法和应用,并且分析了给水管网中水温,自由余氯等因素对生物稳定性的影响。

The paper mainly discusses the biological stability in water distribution system and analyzes the four different indicators of controlling biological stability ： assimilable organic carborn （AOC）, biodegradable dissolved organic carbon （BDOC）, microbial available phosphorus （MAP） and TP. These four indicators are investigated contrastively, and the measurement and application of each indicator are compared separately. And the influences on biological stability are analyzed, which are made by the temperature in water distribution system, free residue chlorine and other factors.
