摘要
再生水的回用是解决水资源短缺的一项重要举措。在输配过程中,再生水与管道内表面会发生复杂的化学变化而产生腐蚀,再生水处理工艺对于腐蚀离子和腐蚀微生物的控制势必成为将来再生水处理工艺的研究热点。因此,建立基于化学腐蚀与微生物腐蚀过程协同的管网腐蚀控制与水质调控应用工艺具有深远的意义。分析了国内再生水处理工艺、混凝与消毒工艺、管网腐蚀与控制的研究进展;从传统再生水处理工艺的角度出发,重点探讨了混凝剂的合理选择、混凝过程控制、消毒工艺优化等关键环节对再生水管网腐蚀的控制作用。
The reclaimed water reuse is an important measure to solve the problem of water shortage. In the process of distribution, some complex chemical changes between reclaimed water and pipe internal surface may happen and thus lead to corrosion. The research of reclaimed water treatment techniques for ion corrosion and microbiological corrosion control will become a research hotspot in the future. Therefore, building up the applied technology for pipeline corrosion control and water quality control application technology based on the synrgism of chemical corrosion and microbial corrosion processes has far-reaching significance. The research progress of domestic reclaimed water treatment process, coagulation and disinfection process, pipeline corrosion and control is analyzed. From the point of view of traditional reclaimed water treatment process, the paper mainly discusses the key links of the reclaimed water pipeline corrosion control such as reasonable choice of coagulants, the coagulation process control and disinfection process optimization.
