摘要:

由于管网系统中存在微量有机物,滋生的细菌会在管道内壁形成厚度不一的附生生物膜。作者就管网内壁生物膜的相关研究进行了综述,以生物膜的形成过程为基础,总结了影响管内壁生物膜的6个因素:水流剪切力、管材、余氯、温度、pH、营养物质。介绍了当前研究中常被使用的两种反应器及取样方法,提出了控制生物膜生长的建议及措施。

Abstract:

Due to the existence of some kinds of minim organic substances in water distribution system,the development of existing bacteria contribute greatly to the formation of bio-film with different thicknesses on inner pipe walls.The formation and control method of this specific bio-film are summarized.Based on the formation process of bio-film,the six major factors which affect the formation are summarized,too;namely the water shear force,pipe material,residual chlorine,temperature,pH,and nutritious substances as well.And then two typical kinds of reactors and sampling methods often used in research are stated.Furthermore,several measures to control the development of bio-filmare given at the end.

Key words: pipenet work, water supply, bio-film
