Key Measures for Controlling Reclaimed Water Pipeline Corrosion——Optimization of Coagulation and Disinfection Processes

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.
