摘要
试验研究了有机营养基质在配水管网中的变化规律及其对细菌再繁殖的影响。结果表明:配水管网中CODMn和不可吹除有机物(NPOC)含量基本没有变化,它们所代表的有机物对细菌生长不起关键作用;管网水中AOC在氯氧化作用和细菌利用的共同作用下,在管网中含量有升高也有降低,没有明显的规律性。AOC是控制细菌再生长的主要因素,管网水中最大AOC含量决定了管网水中细菌再生长能够达到的最大数量。
Changes of organic substrates in drinking water distribution system have been investigated. There is a little variation with the content of oxygen demand （CODMn） and nonpurgeable organic carbon （NPOC） in the network. Organic substrate tested as CODMn and NPOC can not be used easily. AOC levels increases or decreases with no rule because of chlorine oxidation and bacterial utilization. AOC contents controlls the growth of bacteria in the drinking water distribution system. Comparably obvious liner relationship has been found between the maximum HPC and the maximum content of AOC of the distribution system.
