摘要

Changes of total phosphorus (TP) and microbially available phosphorus (MAP) in the drinking water distribution system and its' effects on bacterial regrowth were investigated in a city for environment engineering. The content of TP was 2.93~21.66μg/L and the content of MAP was 0.69~8.01μgPO4~(3-)-P/L in the network. They decreased a little with the extend of hydraulic retention time. They also increased in some sampling point by cooperation of suspended bacteriam, biofilm and granule in the drinking water distribution system. Although an initial conclusion that phosphorus was a factor influencing the growth of bacteria in some sampling points by comparison of AOCpotential, AOC_P and AOCnative had been deduced. Phosphorus was not the key factor that control bacterial regrowth in whole network because of high content of TP and MAP.
