本文介绍了从小规模和中试规模研究中获得的数据，这些研究特别关注低消毒剂残留和磷基缓蚀剂影响下分布生物膜的相互作用。尽管消毒剂的使用增加了腐蚀产物的形成，但会有消毒剂残留水平，在该水平下，传质限制将开始被克服，从而导致更深地渗透到生物膜/腐蚀产物基质中。消毒剂渗透深度增加了微生物失活，降低了生物膜密度。这种消毒剂水平会增加腐蚀产物的质量，但会降低生物膜的密度。该消毒剂水平可定义为残留阈值，并将根据管道材料和水质而变化。 磷基缓蚀剂的使用改变了通常在管道材料上发现的腐蚀产物类型。缓蚀剂的使用减少了管道表面形成的土工石的数量，同时改变了这些材料的静电表面特性。表面静电电荷具有重要意义，因为该电荷调节腐殖物质在管道表面的吸附速率以及微生物与管道表面的静电粘附特性。

This paper presents data obtained from bench-scale and pilot-scale studies that specifically look at the interactions of distribution biofilms under the influence of low disinfectant residuals and phosphorus based corrosion inhibitors. Although the use of disinfectants increases corrosion product formation, there will be a disinfectant residual level in which the mass transfer limitations will begin to be overcome which results in deeper penetration into the biofilm/corrosion product matrix. Deeper disinfectant penetration increases microbial inactivation and reduces biofilm density. This disinfectant level will increase in corrosion product mass, but will reduce biofilm density. This disinfectant level can be defined as the threshold residual and will change depending on the pipe material and water quality. The use of phosphorus based corrosion inhibitors changes the type of corrosion products normally found on pipe materials. The use of corrosion inhibitors reduces the amount of geothite formed on a pipe suface along with changing the electrostatic surface characteristics of these materials. The electrostatic surface charge is of significance because the charge regulates the rate of adsorption of humic substances to the pipe surface along with the electrostatic adhesion properties of microorganisms with the surface.
