供水管网中金属管材的微生物腐蚀机理及防护研究
- Title:
- Research on Microbial Influenced Corrosion Mechanism and Protection of Metal Pipe in Water Supply Pipe Network
- 摘要:
- 我国城市供水管网建设初期大多数采用水泥管、镀锌钢管和灰口铸铁管，近年来在供水管网改造工程中均采用了新型金属管材，如球墨铸铁、不锈钢等。研究表明，当金属供水管道长期运输含卤素离子（主要为氯离子）的生活用水时，微生物腐蚀（MIC）现象难以避免和防控。目前，MIC的机理研究在学术界尚未形成统一的认识，主流观点认为胞外电子传递机制（EET）在MIC中扮演了重要角色，该机制可以简述为附着于管壁的特定电活性微生物膜以直接电子传递方式或间接电子传递方式导致管道发生MIC。针对近年来金属供水管网的MIC问题，概述了三类防护方法，包括主流的化学灭菌剂与增效剂联用方法、处于实验阶段的新型纳米材料抗菌剂方法以及抗菌不锈钢管的研发，以期为供水管网中新型金属管材的推广应用提供借鉴。
- Abstract:
- In the early stages of urban water supply pipe network construction in China, cement, galvanized steel and gray cast iron were the most commonly used materials in related projects. However, novel metal pipe materials such as ductile iron and stainless steel have been increasingly adopted in water supply pipe renovation projects in recent years. Research indicates that microbial influenced corrosion (MIC) poses a significant challenge to prevent or control when metal water supply pipelines transport domestic water containing chronically high levels of halogen ions (mainly chloride ions). The academic community has yet to establish a unified theory regarding the mechanism of MIC. The prevailing view suggests that the extracellular electron transfer mechanism (EET) plays an important role in MIC. This involves the specific electroactive biological membrane attached to the tube wall results in MIC, which is caused by direct electron transfer or indirect electron transfer. In response to the MIC issue with metal pipes, this study systematically summarizes three types of protection methods, including mainstream method of combining chemical sterilization and synergist, experimental novel sterilization methods with nanomaterials and the development of antibacterial stainless steel pipes. The aim is to provide reference and guidance in the promotion and application of metal water supply pipe networks.
