摘要：In this paper, the chemical and microbial erosion effects of reclaimed water on cement mortar lining in a simulated distribution system were investigated. Regular monitoring for the effluent pH, metal ions, nutrients and microbial biomass were conducted. Moreover, X ray diffraction (XRD) analysis for cement mortar lining were also tested to discuss the cement mortar lining deterioration. The results showed that reclaimed water was easy to breed microorganisms during transportation and distribution and had strong corrosion effect for cement mortar lining. The erosion of hydration products in cement mortar and the leakage of those components increased the concentration of effluent pH and metal ions, which would affect the reuse of reclaimed water.
