对某市管网水取样研究了管网水中总磷(TP)和微生物可利用磷(MAP)含量的变化规律及其对细菌在生长的影响。随水力停留时间的增长,管网水中 TP和MAP含量总体呈现降低的趋势。由于悬浮菌、管壁生物膜和颗粒物的共同作用,管网水中的 TP和MAP含量均出现了上升的现象。管网水中总磷(2.93~21.66μg/L)和MAP(0.69~80.1μgPO43--P/L)含量均较高,分析各取样点 TP、MAP与异养菌平板计数(HPC)的相关性表明,TP和MAP均不是该管网限制细菌再生长的主要因素。
對某市管網水取樣研究瞭管網水中總燐(TP)和微生物可利用燐(MAP)含量的變化規律及其對細菌在生長的影響。隨水力停留時間的增長,管網水中 TP和MAP含量總體呈現降低的趨勢。由于懸浮菌、管壁生物膜和顆粒物的共同作用,管網水中的 TP和MAP含量均齣現瞭上升的現象。管網水中總燐(2.93~21.66μg/L)和MAP(0.69~80.1μgPO43--P/L)含量均較高,分析各取樣點 TP、MAP與異養菌平闆計數(HPC)的相關性錶明,TP和MAP均不是該管網限製細菌再生長的主要因素。

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 .The content of TP was 2 9.3~21 6.6μg/L and the content of MAP was 0 6.9~8 0.1μgPO43 - -P/L in the network .They de-creased 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 .Al-though an initial conclusion that phosphorus was a factor influencing the growth of bacteria in some sam-pling points by comparison of AOCpotential ,AOCPand 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 .
