The chemical parameters of water quality were the main factors which influenced the corrosion process in DWDSs（Yang et al.，2012）.The main chemical parameters，including Cl-，SO42-，alkalinity，dissolved oxygen（DO）and p H，were measured in the influents of both ARs（Appendix A Table S4）.There was no significant difference in water quality between the influents of both ARs（p>0.05）.However，the microbiologically influenced corrosion（MIC）also played a great role in stable corrosion scales formation（Sun et al.，2014；Wang et al.，2014；Jin et al.，2015）.The iron-oxidizing bacteria（IOB）and ironreducing bacteria（IRB）can influence the corrosion process and the composition of the corrosion scales.Therefore，the potential corrosive bacteria including IOB and IRB were identified using the most probable number（MPN）technique（Coby et al.，2011）.The results showed that the abundance of IOB and IRB in the biofilms of corrosion scales in AR treated with O3/Cl2disinfection was 1.2×109and 4.5×107cells/g corrosion scales，respectively，which was higher than that in the biofilms of AR treated with Cl2alone（Table 1）.
